This paper is based on the research of Electric Vehicle Energy Storage, which is stable, random, adjustable, good robust, combined with pumping energy storage, applied to the intelligent system of wind-solar complementary and serves for carbon reduction, the objectives are: (1) to promote wind and photovoltaic energy dissipation, (2) to take into account wind and photovoltaic power fluctuations and cluster energy storage systems of Electric Vehicles (EVS), using multiple EVS clusters to coordinate and reduce power fluctuations. The model includes: (1) Load Monitoring Terminal; (2) Server for storing, processing and mapping all collected power data; (3) a set of user-centered visualization and forecasting services for power management; (4) a photovoltaic water pump system for water supply in poor areas, a pumped storage system and an electric vehicle for energy storage. The results show that photovoltaic and wind power have great fluctuation, and the investment and operation cost of energy storage system is high at present. The large-scale deployment of energy storage system will seriously affect the economy of grid-connected photovoltaic and wind power. Only involving thermal power, the total operating cost of the system is 15.103 million yuan, plus scenery water and electric vehicle energy storage combined system after the total operating cost of the system is 876 million yuan. The integration of scenery and water storage improves the economy and stability of the system. Reducing carbon dioxide emissions will have a positive and far-reaching impact on China’s sustainable development.
