Simulation Research on Instantaneous Control in Battery Energy Storage System

Abstract:

The key technology in battery storage system was the control of inverter output waveform. This paper analyzed voltage and current double-closed loop SPWM inverter programs controlled by two kinds of instantaneous values, one was based on inductor-current feedback, and the other one was based on capacitor-current feedback. It made a detailed theoretical analysis to the system designed, and established mathematical model. The simulation study was conducted based on this simulation model which was established by making use of MATLAB/SIMULINK. The simulation result verified the characteristics of SPWM inverter controlled by double-loop instantaneous value based on capacitor-current feedback, that its harmonic distortion rate of output waveform was small, dynamic response speed was fast, output steady state accuracy was high, and capacity of adapting to load was strong.
