Design and implementation of power conditioning for distribution network V2G to electric vehicle and DC charging system

Abstract

Smart interactions among the smart grid, aggregators and EVs can bring various benefits to all parties involved, e.g., improved reliability and safety for the smart gird, increased profits for the aggregators, as well as enhanced self benefit for EV customers. The impact of plug-in electric vehicles (PEVs) integrated into a power distribution system based on voltage-dependent control. The gasoline gate situation has many people turning to electric vehicles as a more environmentally friendly option, especially in smart community areas. The proposed PEVs model was developed as a static load model in power distribution systems under balanced load conditions. The topology of the proposed charger consists of the bidirectional ac/dc and buck–boost dc/dc converters, where it can operate in four quadrants in the active-reactive power plane with the capability of harmonic compensation. Based on the PQ theory, the active and reactive power that includes average and oscillatory components obtained, based on the demand of nonlinear/linear loads and EV battery. In this paper presents the design of a single-phase electric vehicle (EV) on-board bidirectional charger with the capability of power conditioning based on its control in charging/discharging active power based on the demand of EV battery/network or load. The proposed approach was validated and implemented in software packages like MATLAB/OPALRT or etc to integrate the fidelity of the physical simulation and the flexibility of the numerical simulations.
