The aim of the current paper is to present a mimetic algorithm called the chaotic evolutionary programming Powell’s pattern search (CEPPS) algorithm for the solution of the multi-fuel economic load dispatch problem. In the CEPPS algorithm, the exploration process is maintained by chaotic evolutionary programming, whereas exploitation is taken care off by a pattern search. The proposed CEPPS has two variants based on the Gauss map and the tent map. Seven generalized benchmark test functions and six cases of the multi-fuel economic load dispatch problem are considered for the performance analysis. It is observed from the analysis that the CEPPS solution procedure based on the tent map exhibits superiority to obtain an excellent solution and better convergence characteristics than traditional chaotic evolutionary programming. Further, the performance investigation for the considered economic load dispatch shows that the Gauss map CEPPS solution procedure performs better than the tent map based CEPPS to obtain the solution of the multi-fuel economic dispatch problem.

Reactive power management in microgrids with high penetration of distributed renewable energy sources (DRESs) is challenging. The intermittent generation of DRES makes the power management cumbersome. Generally, Flexible AC Transmission System (FACTS) devices such as Distribution Static Compensator (DSTATCOM) are employed for reactive power compensation in microgrids. However, for effective results in microgrids, coordinated operation between DSTATCOM and Distributed Energy Resources (DERs) is required. In this paper, IEC 61850 communication is proposed for realizing coordinated operation between microgrid controller (MGCC), DSTATCOM and DERs. In microgrids, there may be large number of DERs dispersed over a large area. Hence, the underlying communication network technology for IEC 61850 communication must be highly scalable with wide range. Recently developed communication technology Long Term Evolution (LTE) is a promising solution since it offers high data rates, reliability, scalability and longer range. In this paper, the developed IEC 61850 based reactive power management system is tested with the LTE technology and the performance evaluation tests have been performed. Firstly, IEC 61850 messages have been mapped on LTE stack to enable their transmission. Then, simulations over a network emulator have been performed to evaluate the performance of IEC 61850 communication message exchanges over LTE network in terms of End to End (ETE) delays.

With the increasing shift toward electric vehicles (EVs) as a means of transportation, their participation in smart grid operations is gaining importance. If not managed properly, charging a large fleet of EVs could lead to detrimental effects on the smart grid's reliability and stability. On the other hand, EVs can support the grid through vehicle-togrid (V2G) operation and help improve frequency stability and maximize energy use from renewable resources. Managing all these cases requires effective coordination, which hinges on communication between different equipment from varying vendors. Therefore, a standardized modeling that lends itself to interoperability is vital.

Power systems are undergoing an evolution similar to what telecommunications sector went through several decades ago. Analog and hard-wired systems are replaced with automated digital ones. Infrastructure designs are not static anymore and are geared towards accepting new deployments as easily as possible. Limited data exchanges of the past are giving way to detailed data collection, reporting and analysis. When equipped with smart algorithms and techniques such as machine learning, these significantly enhance the capabilities of smart grids. Substations are core component of smart grid, where communication system is integrated. However, achieving a standard substation communication system that can operate with the principles of plug-and-play (PnP) is not a trivial task. Considering the cyber-physical nature of power system equipment, integration requires more diligence for safe operation. Furthermore, there are many different types of substation equipment which are manufactured by, again, countless many vendors. Achieving a common language and interoperability between them is a difficult task. IEC 61850 standard has been taking strides towards that goal. Its object-oriented structure makes its versatile while well-defined modeling blocks ensures compatibility. Recent work has focused on IEC 61850 based modeling of substation equipment, developing message exchange formats for substation functionalities as well as investigating the performance of different communication technologies when they are used to implement IEC 61850 based models. This paper reviews these efforts, their benefits to substation operation and possible future work, including cybersecurity considerations.

Renewable energy has become very popular in recent years. The amount of renewable generation has increased in both grid-connected and stand-alone systems. This is because it can provide clean energy in a cost-effective and environmentally friendly fashion. Among all varieties, photovoltaic (PV) is the ultimate rising star. Integration of other technologies with solar is enhancing the efficiency and reliability of the system. In this paper a fuel cell–solar photovoltaic (FC-PV)-based hybrid energy system has been proposed to meet the electrical load demand of a small community center in India. The system is developed with PV panels, fuel cell, an electrolyzer and hydrogen storage tank. Detailed mathematical modeling of this system as well as its operation algorithm have been presented. Furthermore, cost optimization has been performed to determine ratings of PV and Hydrogen system components. The objective is to minimize the levelized cost of electricity (LCOE) of this standalone system. This optimization is performed in HOMER software as well as another tool using an artificial bee colony (ABC). The results obtained by both methods have been compared in terms of cost effectiveness. It is evident from the results that for a 68 MWh/yr of electricity demand is met by the 129 kW Solar PV, 15 kW Fuel cell along with a 34 kW electrolyzer and a 20 kg hydrogen tank with a LPSP of 0.053%. The LCOE is found to be in 0.228 $/kWh. Results also show that use of more sophisticated algorithms such as ABC yields more optimized solutions than package programs, such as HOMER. Finally, operational details for FC-PV hybrid system using IEC 61850 inter-operable communication is presented. IEC 61850 information models for FC, electrolyzer, hydrogen tank were developed and relevent IEC 61850 message exchanges for energy management in FC-PV hybrid system are demonstrated.

During emergencies, alternative power system operation that utilizes local assets to energize local loads will change the face of the situation. While distributed generators (DGs) such as PV or wind turbines can be utilized for generation, plug-in electric vehicles (PEVs) can act as mobile generators. Different strategies for forming dynamic and networked microgrids utilizing the local generation during emergencies have been widely proposed in literature. However, the underlying communication required for optimal formation of dynamic microgrids and energy management during emergencies is not discussed. Addressing this gap, this paper develops a communication-based energy management system for emergency cases based on IEC 61850 standard. The IEC 61850 based communication modeling provides interoperability and serves for plug-and-play purposes. Furthermore, for establishing communication during emergencies the concept of Cognitive Radio (CR) is proposed in this scheme. Simulation results show the feasibility of modeling and acceptability of its performance.

Power System State Estimation is used to estimate the states of power system. Conventionally, state estimation is an offline method for visualization of power system states. Microgrid are dynamic networks with rapidly changing scenarios. The offline or static state estimates fall behind the actual states of microgrid. Thus, this paper proposes a real time state estimation for microgrids using synchrophasors. Due to high sampling rates of PMU, the data measured through it provide the means for online visualization of microgrid. The real time state estimation is implemented using PMU in Real Time Digital Simulator (RTDS) environment. The proposed method is applied on a modified 14 bus test microgrid. The results are compared with the static estimation and it has been found that the real time state estimation provide accurate visualization of microgrid states than offline state estimation.

Energy Internet is a concept proposed to harness, control, and manage energy resources effectively, with the help of information and communication technology. It improves a reliability of the system, and provides an increased utilization of energy resources by integrating the smart grid with the Internet. A scalable and reliable information and communication architecture is a crucial factor for both the operation and management of the energy Internet. The routing or managing of electrical energy is performed through an energy router (ER), synonymous with a communication router, which routes data packets instead of energy packets. In this paper, a holistic review of the energy Internet evolution in terms of the architecture, types of ERs, and the benefits and challenges of its implementation is presented. An exhaustive summary of the designs and architectures of the different types of ERs is also presented in this paper. The benefits of the energy Internet, along with the challenges of its implementation on a large-scale distributed architecture with the inclusion of renewable energy resources, is discussed. Finally, future prospects for the energy Internet for achieving guaranteed reliability and security is presented.

With the integration of Distributed Energy Resources (DERs) into the distribution networks, the Active Distribution Network Management is becoming quite challenging. The DERs are integrated into the distribution networks through distribution substations. For achieving greater control and ease of operation substations are being automated by employing substation communication network based on standardized communication. IEC 61850 standard has emerged as the most popular standard due to its object-oriented modeling and interoperability features. To ensure smooth and efficient operation of substation automation system, the performance requirements for intra substation communication needs to be evaluated. This paper presents modelling of data traffic in the substation according to IEC 61850 and provides validation through simulation as well as through experimental setup. In the experimental setup, a real bay is replicated in the laboratory for performance validation. The scheme has been validated for VLAN and priority tagging implementation with the obtained simulation results.

The concept of energy internet (EI) is very promising due to its ability to integrate distributed generators and storage devices. Energy routers (ERs) enable highly efficient, reliable and flexible power system operation. To dynamically control and optimize energy flow in EI, an extensive communication is required. Considering the diversity of generators and ERs, it is crucial that such communication is achieved in a standardized and interoperable way. In this paper, an improved energy routing algorithm and its impact in EI operation are demonstrated. Furthermore, a full communication solution is developed for ERs and their interaction with grid operator. This paper proposes an IEC 61850 communication-based power routing algorithm in microgrids. Optimal selection of source and routing path is achieved according to the proposed algorithm and communicated to the ERs via IEC 61850 based communication. The effectiveness of the proposed IEC 61850 communication-based routing algorithm is verified on network emulation platform comprising of IEC 61850 emulator tools and network simulator tool.

Governments set more ambitious goals about CO2 emission reductions and increasing the share of clean energy in the overall generation portfolio. A natural outcome of this trend is more deployment of renewables both at transmission and distribution networks. In addition to well-known environmental benefits, introduction of these non-conventional technologies changes the operation of power systems: e.g. reduced inertia, less stability and more unpredictability. Since most of these novel generation technologies are inverter-interfaced, their behavior under fault conditions are much different than conventional rotating machines. This creates novel challenges in power system protection. Accurate determination of location and type of a fault provides faster system restoration, increased reliability and cost benefits. There are various methods utilized for power system protection. Travelling wave-based fault location methods are preferred due to high accuracy and ultrafast detection capability. This paper reviews the latest developments in traveling wave-based fault location techniques. Signal processing methods hold a key role in information extraction since traveling wave transients have high frequency. A critical review of these methods reported in literature is presented. Application of travelling wave-based protection techniques is examined and special focus is given to distribution systems with high penetration of renewable energy-based generators. Traveling wave-based protection techniques have tremendous potential for future protection applications in smart grid scenarios viz. microgrids and active distribution systems. Being able to detect a fault under different current and voltage conditions make them a very strong candidate for achieving adaptive protection in power systems with high penetration of renewables. Finally, implementation of travelling wave-based fault location system based on IEC 61850 standard is also investigated. Having a standardized implementation is a solid step towards achieving plug-and-play (PnP) in dynamic power networks.

Communication plays a key role in the effective management of virtual power plants (VPPs). For effective and stable operation of VPPs, a reliable, secure, and standardized communication infrastructure is required. In the literature, efforts were made to develop this based on industry standards, such as the IEC 60870-5-104, OpenADR 2.0b and IEC 61850. Due to its global acceptance and strong object-oriented information models, IEC 61850 standard-based communication is preferred for smart grid operations, including VPPs. However, communication models based on IEC 61850 present cybersecurity and scalability challenges. To address this issue, this paper presents an eXtensible Message Presence Protocol (XMPP)-based IEC 61850 communication for VPPs. Firstly, a full mapping of IEC 61850 messages for VPP energy management is carried out. Secondly, XMPP-based single- and multiple-domain communications are demonstrated. Finally, a federation concept has been added to facilitate communication in multi-domain communication networks. These models show that a standard communication model can be implemented with IEC 61850 and XMPP, not only for VPPs but other wide-area communication implementations in smart grids. This not only facilitates plug-and-play (PnP) with easy component additions but secures smart grid communication against cyber-attacks.

IEC 61850 is poised to be the communication standard of the future power networks. Due to its historical evolution, it focuses on substation automation and modeling its entities. There have been recent extensions in the standard's modeling to include other grid equipment as well as distributed generators. However, the configuration of the communication network, as it is outlined in IEC 61850-6, is very substation-focused and cannot be used for microgrids. The microgrid network is a wide-area network with multiple distributed generations (DGs) cannot be configured in a manner similar to a substation communication network detailed in IEC 61850-6. This is because the enhanced system configuration description language (SCL) files cannot be exchanged with each DG while this is not an issue for substation modeling. Also, this would result in multiple copies of enhanced SCL files and is not feasible to implement. Thus, there is a need to develop a process for configuring IEC 61850 based communication networks at the microgrid level. This paper proposes a central configurator and a step-by-step configuration procedure for modeling microgrids according to IEC 61850. Such a configurator assists in connecting IEDs in different locations and updates the system with the new deployment. The process is shown with a centralized microgrid protection scheme by employing a microgrid-level system configurator.

In this paper, out of phase re-closing of islanded microgrid with utility grid is considered. Active synchronization of microgrid with the help of synchrophasors through Phasor Measurement Units (PMUs) is considered. Synchronization is achieved by satisfying the microgrid reconnection requirements specified by IEEE 1547 std. The voltages and phase angles are measured by IEC 61850-90-5 PMUs. The 61850-90-5 PMU, MGCC and DER controller communication are modeled according to IEC 61850 and implemented with UDP/IP. The phase angle differences at PCC, if any before synchronization, are eliminated by MGCC. MGCC coordinates the DERs, as per constraints, to produce the required active power in microgrid to eliminate the phase angle difference. The synchronization process is demonstrated through simulations.

Distance protection is the most widely used protection technique for transmission line protection due to its enhanced selectivity towards fault, fast response, and availability of various relay programming algorithms. However, when faults are detected in zone 2 of a relay, instantaneous tripping is not possible and are cleared after an inherent time delay. Sometimes, this increased disturbance duration may lead to system instability, power quality problems, or may result in increased plant damage. To address this issue, communication-assisted accelerated distance protection has been employed. To have this communication for tele-protection through standardised and interoperable means, an IEC 61850 GOOSE-based communication-assisted distance protection scheme is employed. This IEC 61850 GOOSE-based accelerated scheme must meet the stringent performance requirements. Thus, this study presents the experimental validation and performance evaluation of IEC 61850 GOOSE-based accelerated protection scheme by transporting GOOOSE messages through tunnelling in inter-substation for accelerated distance protection scheme. A system-in-the-loop platform has been developed to analyse the end-to-end delay performances of GOOSE messages under different WAN scenarios here. It has been found that for worst-case scenario, there is a significant operating time saving in the proposed scheme.

Electric Vehicles (EVs) can act as flexible resources in grid due to their bidirectional power transfer capabilities. In microgrids, the bidirectional power transfer capability of EVs through proper scheduling can be utilized to improve reliability, security and quality of supply. Optimal scheduling of EVs is generally managed and controlled through the Energy Management System of microgrid. Since microgrid Energy Management (EM) based scheduling of EVs is data driven, an effective communication between different actors of EM is required. This paper presents a IEC 61850 communication-based EM in microgrids with integrated EVs. Further, augmentation of existing IEC 61850-90-8 logical nodes of EV and its related equipment with new data objects to include information exchanges for discharging operation of EVs have been proposed. Finally, in this paper, XMPP based communication approach and its mapping to the service models for EM problem has been demonstrated.

Intermittency of renewable energy resources makes reactive power management a challenge in microgrids. Since standards do not recommend the use of distributed energy resources (DERs) for voltage regulation and reactive power management in microgrids, therefore, traditionally, locally controlled Distribution STATic COMpensators (DSTATCOM) are widely used. The management of reactive power requirement in microgrids can be improved through communication-based coordinated operation of DERs and DSTATCOM. To make this communication standardized and interoperable, this paper presents modeling of DSTATCOM as per IEC 61850 and an eXtensible Message Presence Protocol (XMPP) for providing scalability and information security. The mapping of IEC 61850 Abstract Communication Service Interface services over MMS ASN.1 XER (XMPP—web protocol) to transform the basic MMS type message into an XML message for their use in XMPP communication is also demonstrated.

A secure, reliable, redundant, resilient, time critical, efficient and interoperable substation communication network (SCN) is a prerequisite for a viable Substation Automation System (SAS). Due to emergence of IEC 61850 as a global standard for substation automation, the interoperability issues among components of substation from different vendors is resolved. The communication network must be fault tolerant and any substantial levels of disturbances should not affect the normal operation of the SAS. Due to digitization in SCN, the communication methodology is mainly focused on exchange of encrypted packet information. Failure of the communication mechanism, even for the order of milliseconds, would lead to catastrophic effects within the substation and also impacts the operation of grid, if not cleared timely. The high reliability of such a system is only possible under a redundant communication network which has a zero switchover time. Hence IEC 62439-3 based redundant protocols such as Parallel Redundancy Protocol (PRP) recommended to be used in SCNs to achieve redundancy and seamless recovery in case of a failure. PRP based SAS along with detailed analysis of underlying process for implementing PRP protocol and its comparison with existing conventional protocols based SCN reported in literature is presented.

Dynamic operation and control of power system is being increasingly done with the help of phasor measurement unit (PMU) based wide area monitoring and control system. The data communication requirements for the PMU based applications are well addressed by IEEE C37.118.2 standard. However, IEC 61850 is now becoming a leading standard for power utility automation needs. A new part of IEC 61850, IEC 61850-90-5, specifying the IEEE C37.118.1 based synchrophasors data transfer according to IEC 61850, will lead to IEC 61850-90-5 based PMU communication networks. A novel IEC 61850-90-5 compliant communication model of PMU is proposed in this paper. We also present a comparative performance analysis of the PMU communication networks supporting the new synchrophasor standard for data transfer, i.e. IEC 61850-90-5, and the existing standard, i.e. IEEE C37.118.2, for end to end (ETE) delay requirements for a modified IEEE 30 bus test system.
