On-Grid AC PEV Charging Station with Battery Storage Integrating RES

Abstract

A renewable energy source (RES) interfaced with utility grid and AC plug-in electric vehicle (PEV) charging station is designed here, as the electric vehicles replacing conventional fossil-based vehicles and supporting green concept is growing tremendously. Local loads as well as PEV loads are connected at common AC bus of the system. Sources are interfaced to AC bus using voltage source converters (VSC). With the large scale integration of electric vehicle and renewable energy sources to the utility grid, there is always a challenge to build up an adaptable and robust control due to intermittent nature and dynamics. Thus, two low pass filters with adaptive noise cancellation algorithm forming as pre-filter and second order generalized integrator frequency locked loop (ALS-FLL) control strategy are used for power flow management, power quality mitigation, voltage regulation, power factor correction. Moreover, the system also feed local loads under dynamic conditions and serves as a PEV charging station. The presented topology is simulated in MATLAB Simulink platform under various perturbations to obtain the effective response of the system.
