Optimized control of DER and V2G systems in PEV charging stations including loss minimization and improved voltage profile

Abstract

This article discusses a application an iterative methods to minimize losses in microgrids by generating optimal active and reactive current references for distributed energy resources (DERs), energy gateways (EGs), distributed generators (DGs) and vehicle-to-grid systems (V2G). The Newton Raphson’s iterative method for optimal active and reactive reference currents was applied on a AC microgrid with 2 and 9 DERs, considering a scenario with integration of V2G systems, BESS and PV systems. The iterative method is developed, applied and investigated in order to stablish a fast time response allowing non-congestion of the electronic power processors (EPPs) in the microgrid. The precision of the results allows microgrid to operate in optimal conditions and minimal power losses on radial and meshed microgrids.
