“…A benefit of this situation is that homes in an island or rural area where no central grid is available can share energy using the MG framework. Moreover, a group of 10-20 houses in an urban zone can interconnect and share extra renewable energies among themselves by this kind of system [47], in which the MG s may connect or disconnect with the central grid for a time based on demand. This can reduce the pressure on the central grid.…”

Energy sharing through a microgrid (MG) is essential for islanded communities to maximise the use of distributed energy resources (DERs) and battery energy storage systems (BESSs). Proper energy management and control strategies of such MGs can offer revenue to prosumers (active consumers with DERs) by routing excess energy to their neighbours and maintaining grid constraints at the same time. This paper proposes an advanced power-routing framework for a solarphotovoltaic (PV)-based islanded MG with a central storage system (CSS). An optimisation-based economic operation for the MG is developed that determines the power routing and energy sharing in the MG in the day-ahead stage. A modified droop controller-based real-time control strategy has been established that maintains the voltage constraints of the MG. The proposed power-routing framework is verified via a case study for a typical islanded MG. The outcome of the optimal economic operation and a controller verification of the proposed framework are presented to demonstrate the effectiveness of the proposed powerrouting framework. Results reveal that the proposed framework performs a stable control operation and provides a profit of 57 AU$/day at optimal conditions.

“…In recent times, many researchers [14][15][16][17][18] have been focused to improve the reliability of microgrid by finding the optimal dispatch of DGs. While maintaining the reliability, the authors considered various objectives like minimization of the cost of operation of DGs, minimization of system loss, and voltage deviation.…”

Summary This paper presents a novel dispatch strategy of distributed generators (DGs) in microgrid for reliability improvement. Energy index of reliability is considered for improvement along with minimization of system losses, system voltage deviation, and cost of DGs. These objectives depend on many criteria like price of DG power, renewable DG power availability, and system loading. The dispatch strategy is developed using bat optimization algorithm. The proposed algorithm is implemented for four seasons: winter, spring, summer, and autumn. For each season, hourly optimal schedules are obtained while maintaining reliability and optimizing objectives. Further, the proposed algorithm is tested for future load enhancement and future price of renewable DGs. The effect of the future load and renewable DG price changes on optimal DG dispatch is tested with IEEE 33 bus distribution system having mixed loads like industrial, residential, and commercial. The feasibility and benefits of the proposed technique are demonstrated with obtained results.
