Abstract
The Distributed PV-Storage Microgrid System (DPMS) validly integrates the distributed photovoltaic power and energy storage unit and effectively improves the power quality problems when the distributed photovoltaic generation is accessed to the distribution network. This paper analyzes the research status of microgrid system, gives the typology structure of distributed micro-grid, and studies the characteristics of distributed photovoltaic generation and energy storage unit. For DPMS, this paper researches the control strategy of underlying device in grid-connected mode and builds a simulation model in Matlab/Simulink environment, which validates the feasibility of the underlying control strategy. It researches the energy management strategy taking peak load shifting as the goal and basing on fuzzy algorithms. According to the different periods of power consumption and the SOC level of energy storage, it determines the energy control strategy and minimizes the operating cost of the DPMS. The validity of the control strategy is verified by the Matlab numerical example.关键词
