Abstract

According to the structure and operating characteristics of DC micro-grid control strategies are analyzed in a DC micro-grid distributed generation units and hybrid energy storage unit. For DC microgrid distributed generation units due to the unstable output power and the DC bus voltage load fluctuation caused by mutations

a new micro-based DC power supply module and hybrid energy storage module collaborative energy management strategies. The control policy to the DC bus voltage signal to charge and discharge mode hybrid energy storage module control. At the same time

it also build a simulation model with photovoltaic cells and mixed-source storage unit

Simulik simulation software for the storage of mixed stream switching mode can be simulated by MATLAB

the results show that the strategy fluctuations in load or photovoltaic cell output power instability the relative stability of the case DC bus voltage to verify the correctness and feasibility of the strategy.
