Abstract

In view of the imbalance of dc bus voltage and power caused by power fluctuation in micro grid

in this paper

a kind of battery inverter control strategy to ensure the harmonization and unity of micro power supply

load and hybrid energy storage system in micro grid is proposed.The dc micro-grid containing hybrid energy storage system is taken as the research object.Four types of operation modes of micro grid are summarized in accordance with the power flow between modules of the micro-grid

and the dynamic characteristics of the micro-grid under various operationmodes are simulated and analyzed on the Matlab/Simulink platform.It is shown by the simulation resultthat the proposed strategy can

on the condition of assuring smooth transition between different operation modes of the micro grid

suppress power fluctuation of the system and stabilize DC bus voltage.
