The efficient utilization of renewable energy has been a research hotspot in recent years, but the characteristics of instability and intermittence limit the large-scale and efficient utilization of variable renewable energy such as solar energy and wind energy. This paper mainly studies the transformation and application of sustainable renewable energy based on the principle of energy storage. Firstly, this paper analyzes the necessity and economics of energy storage system in detail, and constructs a large-scale hybrid energy storage system composed of gravitational potential energy storage, battery and super capacitor. Taking IEEE-39 bus test system as an example, the proposed method is simulated by MATLAB simulation software to verify the correctness and efficiency of the proposed method. The simulation results show that the method proposed in this paper meets the economic rationality, and can realize peak shaving and valley filling.
