Coordinated Operation of Power System and Energy Storage In the Presence of High Penetration of Solar Generation

Abstract

Due to the randomness and volatility of solar power generation, energy storage system (ESS) with its peak shaving and valley filling ability is widely used in electrical power system (EPS). This paper proposes a coordinated operation model of power system and energy storage with solar generation. The proposed model minimizes system operation cost when considering high penetration of solar generation. Case studies illustrate effectiveness of the proposed model especially the ESS operation for reduce solar spillage in high penetration and assure the security of power system.
