Energy modeling and planning problems associated with technical, economic, political, and social development have been critical concerns in energy system planning and greenhouse gas emission control for both national and worldwide for many years. This paper modeled and analyzed the current and future energy supply and demand for an oil-rich energy system because energy intensity is very high in such countries. A high shared fossil fuels energy system is modeled, and an appropriate energy mix is proposed to meet the national commitment in Paris Agreement. The EnergyPLAN is used to model the energy system. Hourly actual energy demand and supply are provided for 2004–2016 for all energy sectors and subsectors and anticipated 2030. Five different scenarios are analyzed, and results show that the power sector is more influential than other energy demand sectors. Efficiency improvement of the thermal power plans and the integration of renewable energy resources into the power sector are more useful for reducing Total Primary Energy Consumption, CO2, and variable cost than other scenarios. In the proper scenario, a 1% improvement in the thermal power plants efficiency and 22% annual average growth rate in renewable energy capacity, 4% CO2 reduction can be achieved. It is concluded that in oil-rich counties such as Iran, the energy system efficiency improvement, particularly in electricity production, is more useful for the overall CO2 reduction goals. Efforts for total CO2 reduction benefit the national energy system economy, and the international community will benefit from a more efficient energy system. We believe that by total primary energy supply reduction in oil-rich countries, the international market's energy supply will be increased, which further reduces the pressure on the global oil and gas prices.

The present paper intends to maximize the amount of solar and wind power produced while minimizing the tested network's annual energy loss. It also wants to improve the voltage profile and reduce the dependence on the upstream network. Two types of distributed generation sources, i.e., wind DGs and solar DGs, are investigated. In this paper, the network loads vary according to the local consumption pattern. This research shows that the optimal utilizing of solar and wind distributed generation sources causes energy loss to decrease by about 43 and 94 percent, respectively. Besides, the grid will receive 1109.49 GWh of energy from the upstream power grid without distributed generation sources. In contrast, solar and wind generation sources receive only 801.47 GWh and 125.84GWh, respectively. Additionally, in solar and wind scenarios, micro-grid sends 71.62 and 102.42GWh energy to the upstream network. Also, by calculating the emission reduction, it was observed that by installing 465.45 MW of the wind turbine units in the area under consideration, the country's CO2 equivalent is reduced by 754,586 tons, and the country's primary energy is reduced by 263,916 TOE.

In recent decades global warming has turned into an international concern. Anthropogenic Greenhouse gases (GHG) are produced through burning fossil fuel leading to an increase in the global warming effect; thus, GHG reduction contributes to mitigating climate change. Utilizing renewable energies, increasing efficiency of and capacity factor (CF) of existing power plants, and recycling waste energy in various industries are convenient solutions to improve the energy systems performance to reduce fossil fuel consumption, leading to GHG emission. So, there is a substantial need for planning and evaluating the energy systems in which various technologies are used, technically and economically. Theis study's main objectives are utilizing the capacity of renewable energies such as biomass, wind, solar, hydropower, and enhancement of CF and efficiency of the power plants in the Mazandaran region in the south of the Caspian Sea. The energy system considered for the region is modeled and analyzed by six scenarios in this paper. The results indicated that the share of renewable energies in electricity production could be increased from 5.4% to 47.7%. The results of cost analysis show that by applying the sixth scenario, which is integrated policies of increasing RER share and improvement of efficiency and capacity factor. The trends of total annual cost, CO2 emission, and fossil fuel consumption are reduced compared to the business as usual (BAU) scenario. The average cost saved by this scenario is about 220 MUSD/year. The average amount of fossil fuels and CO2 emission save are 11TWh/year and 2.438 Mt/year between 2020 and 2030, respectively.

The present study was conducted to predict the electricity status based on scenario design and energy modelling using optimization approach by 2050 in Khuzestan, Iran. Two scenarios were proposed, one investigating the current trend called the BAU (Business as Usual) and the other SMD (Sustainable Management and Development scenario). According to the BAU scenario, electricity consumption will reach from 29.08 to 73.79 TWh during 2017–2050, reducing renewable energy sources from 30.3 to 18.9%. In addition to being more dependent on fossil fuels and increasing greenhouse gas emissions, power plant capacity will not be responsive to the peak of electricity consumption. However, this situation will be improved in the SMD scenario using consumption management strategies, increased efficiency, and resource development. Reducing electricity demand and generation by 2.5 and 28.2%, respectively, will reduce environmental externalities by 658.8 million and saves 173 MTCO2e. The SMD scenario's benefit would be equal to 6,376.8 million compared to the BAU considering all socio-economic and environmental indicators. The results show that relying on fossils to generate electricity will cost more in long-term. The SMD scenario with the participation and development of renewables with greater dispersion reduces transmission losses and optimizes electricity generation to minimize environmental hazards.

Dealing with the challenge requires appropriate planning. So as of energy intensity and the environment situation in Iran the energy systems planning is essential. About 92.4% of electricity in Iran is produced by fossil fuels in thermal power plants and has significant share for creating air pollution. Diversification of energy resources is a solution to improve the energy security and reduce environmental risks through the transition to renewable electricity generation. This study has been done by resource feasibility, scenario design and energy modelling to predict the supply and demand of electricity and aims to investigate the benefits of introducing renewables in Iran energy system. Identifying 92 potential areas, prioritizing resources, and estimating capacity by 2035 to synergize the share of renewables is the result of the feasibility section. By evaluating the potentials, the solar with 64,730 MW will have the highest power potential and the wind with 51,110 MW is the next. In modelling section, the electricity generated by renewable energies by the year 2035 is equal to 83.73 TW h in REN scenario, which is almost 11.93% of the total electricity produced but in the BAU scenario, this share is equal to 2.38%. The reduction in fuel consumption in the REN scenario compared to the BAU scenario is also equal to 82.97 MtOe, which would result in a reduction in emissions of equivalent to 221.54 MtCO2e. These are the only benefits of using 30% of the renewables potential, and if more attention is paid, it is definitely the most effective way to develop sustainable energy system.

Currently, 89% of thermal demand in the building section of Iran is supplied by natural gas. Although Iran has appropriate natural gas reservoirs, it can be used more in the current industrial infrastructure if renewable resources supply buildings' thermal demand. This research aimed to find a reliable solution to replace natural gas with solar or wind energy on a national scale using a simulation approach. Different scenarios were discussed for this research by considering the amounts of CO2 emission and total energy cost. The results showed all procedures led to CO2 emission reduction due to reducing natural gas consumption. Moreover, using heat pumps with generated electricity from solar or wind resources increased the average total cost of about 127% and 326%, respectively. Therefore, introducing heat pumps with renewable electricity was not economical for supplying buildings' thermal needs in Iran. Based on the results, using solar thermal collectors decreased the average total cost by about 13%. In conclusion, considering the current national natural gas distribution network in Iran, using solar thermal collectors was the best alternative solution.

There is a great interest in the utilization of various renewable energy resources in the agricultural sector due to the production and consumption of limited fossil fuel resources and the ever-increasing energy demand in developing countries such as Iran. Investigation of agricultural production in various provinces of Iran revealed significant potential for bioenergy production in this sector including ethanol, butanol, methane, hydrogen, and biodiesel. Statistical data for each province including population, cultivated land area, energy and fertilizer consumption, and agricultural production rate were used to calculate CO2 emissions and bioenergy replacement potential. The energy demand, potential, and related CO2 emissions were computed and discussed. The energy demand in the agricultural sector was 36.2 TWh, 13.2 ktons, 2257.7 ktons, and 2408 Mm3 of electricity, kerosene, diesel, and natural gas, respectively. On the other hand, the potential of bioethanol, biodiesel and biogas was respectively 2.932×106m3, 0.44×106tons and 2.647×109m3. These biofuels are processed to replace fossil fuels. In the case of bioethanol and biogas, 10% of the calculated potential and total potential of biodiesel was assumed to be accessible. Accordingly, the potential to recover the bioethanol, biogas, and biodiesel demand is 100%, 11%, and 19.5%, respectively. In this scenario, the total CO2 emissions from the conventional energy system was 46.7 million tons per year, which can be decreased by 77.2% by changing the fuels.

Nowadays, by increasing energy demand and considering the importance of environmental issues in recent decades, the use of renewable energies is expanding. Among renewable energies, wind power and its technology are growing and evolving more rapidly. Resource assessment in Iran has revealed the significant potential of wind energy around the country. To further develop wind energy in the country and create large-scale wind power plants, the consideration of distributed power generation using small wind turbines for applications in agricultural and residential use is needed. Conventional small wind turbines and small wind lens turbines have been developed in recent years. In this research project, a small wind lens turbine is designed. The advantages of this turbine are an increased production capacity and reduced cut-in speed and noise pollution. In this study, a lens (or shroud) is added to a small turbine, and the maximized annual energy production (AEP) and minimization of the levelized cost of energy (LCOE) are modeled. We applied the NSGA-II algorithm for optimization to find the best answer. The input parameters in the objective function of the AEP are cut-in, cut-out, rated speeds, scale factor, and shape factor. Additionally, the input parameters in the objective function of the LCOE are the power production, initial capital cost, annual operating expenses, and balance of energy. The results indicate that installing a wind lens turbine in Kish Island led to an LCOE decrease of 56% on average, and we can see an 83% increase in the AEP. In the Firoozkooh area, an average reduction of 59% in the LCOE and 74% increase in the AEP for a wind lens turbine is observed.

Despite the high potential of renewable energy sources in Iran, the current energy system in the country is highly dependent on fossil fuel resources because the abundance of oil and gas resources in the country has made it less feasible to harvest renewable energy. Nowadays, climate change and the increase in greenhouse gases (GHG) emissions have led to measures such as determining CO2 taxes that make renewable-based energy systems more profitable. Southern Iran, with its arid climate, has a high potential for the integration of solar energy into the existing energy system in order to maximize its share on the energy system; therefore, in this research, five scenarios were defined and applied to model the energy system for 2025 and 2030. Each scenario was assumed to maximize the solar energy share for the supply of heating, cooling, and electricity demand, such as photovoltaics (PV) and concentrated solar power (CSP). The bottom up EnergyPLAN was applied to model the energy system and scenario computations. The results of the scenarios were compared based on annual CO2 emissions, costs, total primary energy supply, and critical excess electricity production. Based on the results, all scenarios were able to reduce the CO2 emissions; however, the PV based scenario had the least costs and utilized 1954 MW of PV power plant to supply the demand with 599 M€/year costs. Natural gas was largest energy resource of the system; due to the 17% reduction in the total primary energy supply compared to BAU and Best Scenario (S5) for 2030, about 20 TWh/year of the natural gas was saved and was ready for export. According to the Paris Agreement, the permissible amount of CO2 emissions for this province in 2030 is about 9.76 Mt, which is 5.59 Mt in Best Scenario (S5). Furthermore, sensitivity analysis was run for the costs of the business as usual and PV based scenarios under different natural gas prices and emissions tax rates from 0.025 to 1.92 €/Gj and 4 to 20 €/kg of CO2, respectively. According to the findings, when the natural gas price increased to 0.521 €/Gj, the renewable-based plans became feasible, and increasing the CO2 tax caused the cost differences to rise.

This paper presents a 3D numerical model for the north-west (NW) Sabalan geothermal system, including the unsaturated vadose zone overlying the system, based on a conceptual model derived from data gathered from 10 deep exploration wells. To achieve the goal, the EOS3 (water-air state equation) module of the Tough2 simulator was utilized to develop the model. The model was constructed from a rectangular prism, which is 11.5 km long, 8 km wide, and variable depths ranging from 3.8–5.11 km. The 21 horizontal layers with a thickness range of 100−1000 m were expanded from the maximum height of 4110 to -1000 masl. A total of 22 rock types were distributed within the model based on the availability of rock units and geological structures derived from the exploration wells. The permeability of these rock types varied from 1.0 × 10−17 to 9.0 × 10-13 m2. The model was initially run to match the natural state of the reservoir. A close agreement was obtained between the measured data from the exploration wells, and the model results for subsurface temperatures and pressures. In the calibrated model, a high temperature upflow zone was required in the southeast part of the area (below the exploration sites D and E). This flow rises to the land surface through permeable zones, faults, and fractures, and finally appears on the earth’s surface as hot springs in the northwestern part of the area. This model was then used as the initial model to predict the reservoir performance for the 50 MWe scenario. The results showed that the reservoir can generate about 45 MWe by assigning two makeup wells and remain at this level for more than 30 years.

The power supply and demand have been studied, modelled, analysed, and foresighted as one of the most important energy carriers. The Business as usual (BAU) scenario was compared based on continuing the status quo with seven other proposed possible scenarios up to the horizon 2050. Possible solutions such as demand management, increased productivity, upgrading power plant technology, and development of energy resources attempt to reduce electricity demand, as well as improving and promoting the share of renewable energies in power generation and reducing emissions. The cost–benefit technique has also been used to analyse the economic and environmental benefits. As a results, a Khuzestan electricity policy scenario that has a well-coordinated and cost-effective solution for both supply and demand. It is preferred scenario for flexibility and stability of grid with a $3,549 million profit with 35% renewable energy share.

Buildings are one of the most important emitters of CO2, causing climate change. This fact, together with the finiteness of conventional energy, results in the Zero Energy Building (ZEB) being future buildings. Although ZEB is a simple concept, but there is no valid universal definition. This is one of the significant building's energy systems challenges, which need to be appropriately addressed. Thisreview paper is going to review and summarize existing definitions to address a comprehensive definition of ZEB. The published articles were reviewed, and the definitions of zero energy buildings were drawn out. Then the differences in the existing definitions were analysed. Finally, suggestions are presented on suitable definitions from four perspectives, including energy, carbon, exergy, and economics. This definition is used as a standard communication by energy planners and policymakers to facilitate their decision making on energy transition.

The increasing need for energy, the limitation of fossil fuels, and the environmental and economic aspects of the conventional energy system have caused a lot of research and developmental activities regarding renewable energies. In the current paper, we analysed the feasibility of utilising a hybrid solar system to provide electricity, hot water, and drinking water in the parks of Tehran, Iran. The proposed hybrid system was simulated to investigate its lifetime performance using PVsyst, TSOL, and RETScreen. Furthermore, to validate the simulation, a small-scale system was manufactured and experimentally tested. The simulation and experimental results confirm the feasibility of the system regarding the technical and economic aspects. Exploring environmental issues also emphasises the implementation of such a system for future designs. It is to be noted that the purposed pattern of the hybrid system could be easily generalised and extended for other sites in urban and rural contexts. The equity paybacks of the PV, solar hybrid water heater, and solar water desalination sections were 4.4, 2.3, and 1.6 years, respectively.

This study develops a mixed-integer linear programming (MILP) model for the optimal and stochastic operation scheduling of smart buildings. The aim of this study is to match the electricity demand with the intermittent solar-based renewable resources profile and to minimize the energy cost. The main contribution of the proposed model addresses uncertainties of the thermal load in smart buildings by considering detailed types of loads such as hot water, heating, and ventilation loads. In smart grids, buildings are no longer passive consumers. They are controllable loads, which can be used for demand-side energy management. Smart homes, as a domain of Internet of Things (IoT), enable energy systems of the buildings to operate as an active load in smart grids. The proposed formulation is cast as a stochastic MILP model for a 24-h horizon in order to minimize the total energy cost. In this study, Monte Carlo simulation technique is used to generate 1000 random scenarios for two environmental factors: the outdoor temperature, and solar radiation. Therefore in the proposed model, the thermal load, the output power of the photovoltaic panel, solar collector power generation, and electricity load become stochastic parameters. The proposed model results in an energy cost-saving of 20%, and a decrease of the peak electricity demand from 7.6 KWh to 4.2 KWh.

Renewable energy sources and electric vehicles are promising solutions for reducing fossil fuel consumption and environmental impacts within the electricity and transportation sectors. In this study, a new electric vehicle aggregator framework is proposed and four different electric vehicle charging scenarios have been modelled to analyse the impact of electric vehicles on the considered industrial microgrid. The remarkable point of this aggregator is reducing the computational time in the presence of a high penetration level of EVs. The EV charging scenarios include; no electric vehicle, uncoordinated electric vehicle charging, unidirectional and bi-directional vehicle to the grid. Diverse types of renewable energy sources such as wind turbines, solar PV panels, and geothermal units are considered, and an energy scheduling model is implemented. Uncertainties of renewable energy sources and electric vehicles behaviour (arrival time, departure time, and travelled distance) are modelled with their probability distribution function from related historical data. Also, for demand-side management, the Time of Use (TOU) strategy is implemented and three cost levels are defined, which contain off-peak, mid-peak, on-peak, and their cost levels. Results show that the suggested vehicle to grid model is effectively reduced the operation cost and maximize renewable energy share. Eventually, a sensitivity analysis is executed, and the result illustrates that a model with an increase in the penetration level of electric vehicles from (100 to 2000) in the industrial microgrid have better effectiveness in relative operation cost in electric vehicle smart charging schemes. It means relative operation cost, which is related to the unidirectional and bi-directional decrease from 0.996 to 0.95 and 0.988 to 0.831, respectively.

Increasing energy demand, together with environmental concerns, results in a significant tendency toward the research and development of renewable systems and particularly solar energy. Locating in the sunbelt of earth, Iran has great solar potential. However, due to the noticeable amount of dust activities in the Middle East, there are several challenges in the way of development of the photovoltaic systems. The current article provides a comprehensive literature review on the photovoltaic status in Iran regarding the climate conditions, photovoltaic development potentials, energy policies within the country, and photovoltaic experiences. A regionally focused review of the conducted works is provided to investigate the effect of dust activities on the output performance of photovoltaic systems. A focus on dust origins, frequency, and specifications is a priority in order to analyze its impacts on the performance of photovoltaic systems. Furthermore, a review of cleaning methods to overcome the dust deposition problem is provided. The comprehensive literature review conducted in this article is represented to researchers, designers, and engineers dealing with photovoltaic systems in regions with dust problems such as the Middle East and particularly Iran.

One of the main objectives of human society in the present century is to achieve clean and sustainable energy through utilization of renewable energy sources (RESs). In this paper, the main purpose is to identify the locations that are suitable for solar energy in the Kurdistan province of Iran. Initially, solar-related data are collected, and suitable criterion and assessment methods are chosen according to the available data. Then, the theoretical potential of solar energy is assessed and the solar radiation map is prepared. Moreover, the technical potential of various solar technologies is evaluated in that study area. These technologies include concentrating solar power (CSP) and photovoltaic (PV) in power plant applications, and rooftop PV panels and solar water heaters in general applications. The results show that the Kurdistan province has the potential capacity for 691 MW of solar photovoltaic power plants and 645 MW of CSP plants. In the case of using solar water heaters, 283 million cubic meters of natural gas and 1.2 million liters of gasoline could be saved in fuel consumption. The savings in the application of domestic PV will be 10.2 MW in power generation.

In this study, Computational Fluid Dynamics simulations are carried out to assess the effect of duct geometry on power output and flow characteristics for a custom-designed wind turbine. The results show that the elevation of power output for a wind turbine is strongly reliant upon the shape of the duct. While before reaching a certain tip speed ratio, ducting would actually decrease the power output level. It is also argued that the velocity recovery index can also be considered dependent upon to the duct geometry. While the record power coefficient for the bare turbine is calculated to be 0.46, a power coefficient of 0.78 is shown to be reachable by adding a duct, which indicates an increase of approximately 70%. The near wake flow was analysed and a relation between the back-pressure level and the calculated power output was verified. The study also presents a framework for sizing the optimum duct.
