SMES Control for Power Grid Integrating Renewable Generation and Electric Vehicles

Abstract—This paper presents a superconducting magnetic en-ergy storage (SMES) control system for the power distribution grid which integrates renewable generation and electric vehicles (EVs) together. Based on a 33-bus 4-lateral radial distribution system, coordinated control is developed. With the use of SMES, any tran-sient unbalance caused by wind power variation can be recovered so that the system frequency can be stabilized. Also, with the use of EVs, the steady-state load demand can be redistributed to facilitate the adoption of wind power generation. Finally, simulation results verify that the use of both SMES and EVs can effectively perform power balancing under both the transient and steady states.
