Design and Simulation of Hybrid Energy Storage System With PV, Battery and Supercapacitor using PMSM Drive for Electric Vehicle

Abstract

This paper presents the design of a Hybrid Energy Storage System using PV, Battery, and Supercapacitor. The proposed system uses PV as the primary source of energy while Battery and Supercapacitor are the secondary sources of energy, they would supply the power to load when the PV Power is less to fulfill the demand of the load. In this paper, the supercapacitor supplies the high-frequency current reference along with the battery error current which is given as the reference for the SC Energy Storage System whereas the Battery provides the low-frequency component resulting in an improved voltage profile as compared to that of the conventional methods. The proposed system provides better performance and higher efficiency.
