A virtual energy storage system (VESS) logically shares a physical energy storage system among multiple units. In resource sharing, the distribution of benefits is a critical problem.
Optimal scheduling for generation sources to get economic benefits of MG comprised of RESs and Energy storage system (ESS) is proposed using PSO in [24] and improved PSO in [25].
Abstract. The microgrid represents a controllable electric entity that contains different loads into distributed energy resources. All typical microgrids use two or more sources by which electricity is generated, at least one of which is a renewable source. In this respect the main issues of the energy storage systems (ESS) are the enhancing …
