Abstract:

Based on the energy use structure and actual energy use requirements of the park,a set of optical storage microgrid system of the campus is designed.The photovoltaic power generation system is used as the new electric energy supplement in the park,which reduces the energy cost of purchasing electricity from the grid.By configuring the electrochemical energy storage system with a certain capacity,multiple functions such as energy time shift and backup power support of the campus energy use structure are realized.The overall design and subsystem design of microgrid are summarized,and the operation and test of microgrid are introduced.The operation analysis shows that the system can effectively improve the coordination ability of energy supply and demand,promote the consumption of clean energy nearby,meet the diversified energy needs of the park,and have a good application and promotion prospect.

Key words: photovoltaic and storage, microgrid, energy management system, park
