Study on Energy Management Strategy for Optical Storage Microgrid Considering Dynamic Load Fluctuation

In the context of distributed energy sources being continuously integrate to the grid, the interaction between the grid and the electric load is becoming more and more frequent. In this paper, based on the analysis of the photovoltaic storage co-generation system, the consideration of PV power output size and storage battery charge state are combined to formulate the dynamic load regulation strategy, and the capacity configuration problem and operation strategy problem of the energy storage system are studied. The control strategy of the energy storage converter is adjusted according to different operation modes of the microgrid (DROOP control in case of islanding and PQ control in case of grid connection), which can maximize the stability and efficiency of the microgrid operation. Finally, modeling simulation analysis in MATLAB/Simulink and hardware-in-the-loop experimental platform are built to verify the feasibility of the control strategy.
