Research on Voltage and Frequency Regulation of Micro-Grid with Distributed Energy Storage

Abstract

Aiming at the increasingly widespread use of distributed energy storage, building a model of distributed energy storage for Micro-Grid voltage regulation and frequency modulation. The waveforms of the frequency, active power, reactive power and bus voltage of the Micro-Grid are given. Firstly, the control method of distributed energy storage inverter - droop control is introduced. Secondly, based on MATLAB/Simulink platform, a Micro-Grid model with distributed energy storage system output to adjust voltage and frequency is built. Through the simulation, the role of distributed energy storage in the Micro-Grid is verified, which lays a foundation for the research of distributed in the Micro-Grid.
