“…Mobashsher et al [4] introduced an Optimal Voltage Control (OVC) framework for island microgrids (MGs) as an integrated hierarchical control scheme. They started with the optimization of the bus voltage adjustment points in the third level, which were then effectively followed by a secondary control that controls the distributed energy sources.…”

Instability of voltage is a problem that has been occurring in recent years due to excessive exploitation from equipment and an increase in demand for load across the distribution system. Shortage of the reactive power in the power networks, especially distribution networks, pushes the system toward voltage instability and leads to voltage drop as well as voltage fluctuations in the feeder. One of the potential solutions for compensation is to install thyristor switched capacitor (TSC). Although TSC can reduce the total costs of compensation, the static error will reduce compensation. For this purpose, an active power filter (APF) can be applied to resolve errors resulting from TSC due to features of continuous compensation and quick dynamic response. In this research, the combined method was presented, including TSC and APF of a controllable active power injection and with appropriate switching based on the study of voltage drop in the radial distribution networks and improvement of power quality. The suggested model was executed by MATLAB software, whereby results of improvement and provision of the stability conditions (dynamic and static) of voltage and current were observed.

“…Jafari et al [14] proposed an optimal operation approach of MG, where the demand response was considered as shifting technique in responding to energy market price. The optimal management and control of the microgrid is a hierarchical structure, where the optimal operation and unit commitment (UC) strategy is within the tertiary level [15,16].…”

This paper proposes an approach to improve the system arbitrage and reduce peak load by managing both the generation and load sides simultaneously. The peak load reduction is achieved using a load control program, while the arbitrage is enhanced by minimizing the operating and emission costs. The load management and minimization of operating cost are combined in an optimization approach in a multi-objective framework. The storage battery is utilized to contribute in the shaving of the peak load and reducing the operating and emission cost, where the battery aging is taken into account in the proposed model. The management of load sides is considered as decision variables in the approach. A mixed-integer quadratic program is employed to formulate the optimization approach. The proposed approach is applied to a smart low-voltage distribution grid. The results show that the management of both the demand and generation sides reduces the operating and emission costs and improves the load factor of the system.

Microgrids, comprising distributed generation, energy storage systems, and loads, have recently piqued users’ interest as a potentially viable renewable energy solution for combating climate change. According to the upstream electricity grid conditions, microgrid can operate in grid-connected and islanded modes. Energy storage systems play a critical role in maintaining the frequency and voltage stability of an islanded microgrid. As a result, several energy management systems techniques have been proposed. This paper introduces a microgrid system, an overview of local control in a microgrid, and an efficient EMS for effective microgrid operations using three smart controllers for optimal microgrid stability. We designed a microgrid consisting of renewable sources, Li-ion batteries, the main grid as a backup system, and AC/DC loads. The proposed system control was based on supplying loads as efficiently as possible using renewable energy sources and monitoring the battery’s state of charge. The simulation results using MATLAB Simulink demonstrate the performance of the three proposed microgrid stability strategies (PID, artificial neural network, and fuzzy logic). The comparison results confirmed the viability and effectiveness of the proposed technique for energy management in a microgrid which is based on fuzzy logic controllers.
