China International Youth Conference on Electrical Engineering (CIYCEE 2020)

Focused on the application of the energy storage system configuration in the urban load center, this study first establishes the energy storage battery life calculation model and the life cycle cost model according to the operating
characteristics of the energy storage system. Subsequently, the indicators model of direct economic benefits and indirect technical benefits of the energy storage system is analyzed and established with the consideration of simultaneous profitability of power generation and demand side under regarding the power grid as the main body of investment, and indicators values are obtained through the unit scheduling model. Then, the benefit evaluation system of the energy storage system is constructed based on the subjective and objective weighting method and the cloud matter-element theory. Finally, the proposed method is tested on IEEE 33 bus systems. The simulation results show that the proposed method can better comprehensively reflect the actual value of energy storage power stations in the urban load center.
