Dynamic simulation of EV fast charging with integration of renewables

Abstract

This paper presents the results of a dynamic simulation of various scenarios of Electric Vehicle (EV) fast charging in combination with renewable generation. Based on a hypothetical distribution network, the possible benefits from coordinated controls of fast charging and renewable generation are studied under grid connection and islanding condition. For grid connection condition, strong and weak grid scenarios are both simulated; for islanding condition, energy storage requirements are considered. The simulation results show that with proper control strategies, fast charging infrastructure can help to compensate active and reactive power in different conditions, so as to improve the operation performance of power systems with renewable energy integration.
