Design and Implementation of a 3 kW Single-Phase BESS Using ARM & FPGA

The purpose of this paper is to design and implementation of a battery energy storage system (BESS) for residential application. BESS Power circuit consists of a two-stage bidirectional DC-DC converter and a full-bridge DC-AC single-phase inverter. In this paper, a proportional-resonant (PR) controller with harmonic cancellation is used as the grid-connected inverter current controller. This method has the ability to control active and reactive injected power to grid with standard total harmonic distortion (THD < 5%). The BESS is simulated using Simscape library of MATLAB and is implemented using ARM and FPGA. Both the simulation and the experimental results prove the satisfactory performance of the BESS.
