Abstract:

With the technological revolution and industry transformation, integrated energy service will be the trend of energy industry. With the growth of electric vehicles annual sales, the demand for charging piles is increasing. Taking a integrated energy system in Fengtai District as the research object, the optimal designs for photovoltaic power generation, energy storage, fast/slow charging piles and energy management system were analyzed. Based on the energy generated by photovoltaic system hourly, energy demanded by energy storage and charging piles, and energy prices, the energy management strategy was adjusted and the economic profits was maximized,which provides reference for solar energy storage and charging in integrated energy systems.
