Currently thousands of people around the world lack access to electricity in remote areas, the demand for energy in these areas can be effectively supplied by renewable sources, hybrid photovoltaic-wind systems attract attention due to the reduction of implementation costs in In recent years and a high reliability in the supply, the optimal model of the system is considered an influencing variable in the optimal size of the system as it is defined according to the conditions of the problem or study area. The article presents a series of simulations to find the feasibility of the implementation of the isolated system, the economic technical parameters are analyzed to obtain the lowest cost of energy to be considered competitive, the levelized cost of energy is directly related to the cost optimum of each one of the sources, which leads to a considerable increase in the introduction of this type of hybrid systems and the disenchantment of using generators based on fossil fuels.

Increasing the generation of renewable energies to reduce the consumption of fossil fuels that produce high concentration of greenhouse gases is the priority that several governments have set for themselves in the medium term. In this paper, the modeling of a solar thermal energy generation plant is carried out. The climatic data correspond to two coastal cities and an island in Ecuador. The main contribution is the simulation of a complete model of solar collector fields and power conversion systems, in which the variables of output temperature and oil flow intervene at the same time. Previous research uses only the outlet temperature to evaluate the power plants. The model of the solar thermal plant is composed of a solar collector field, a storage tank, and an energy conversion system. As a result, a model of a solar thermal plant is obtained that allows to make decisions when considering the incorporation of microgrids in electrical systems isolated. The use of solar thermal technology allows to reduce the risk of spills from the transport of fossil fuels on ships. In addition, the CO2 emissions involved in the construction, operation, and maintenance of a solar thermal power plant are detailed.

The increase of renewable energy generation to change the productivity of a country and electrify isolated sectors are some of the priorities that several governments have imposed in the medium term. Research centers are looking for new technologies to optimize the use of renewable energies and incorporate them into hybrid generation systems. In the present work, the modeling of a solar thermal energy generation plant is being carried out. The climatic data used belong to two coastal cities and one island of Ecuador. The contribution of this work is to simulate a complete model of SCF and PCS, in which the variables of outlet temperature and oil flow are involved at the same time. Previously investigations use only outlet temperature for evaluating power plants. The model of the solar thermal plant is composed of a field of solar collectors, a storage tank, and an energy conversion system. As a result, we obtain a model of a thermosolar plant that will allow us to make decisions when considering the incorporation of micronetworks in systems isolated from the electrical network. The use of thermosolar technology allows the reduction in the risk of spills by the transport of fossil fuels in ships. The study of the CO2 emission factor in Ecuador from 2011 to 2018 is also carried out.
