  • Abstract:

        Energy storage technology has been one of the key supporting technologies in future power systems with high penetration renewable energy. Scientific evaluation method is an important basis for measuring the value of energy storage. This paper proposes a system value evaluation method, and analyzes the value composition of energy storage comprehensively, which includes direct value and indirect value. Meanwhile, the synergistic matrix of energy storage applications is given, the characteristics of system value of energy storage are analyzed, and multiple values of energy storage in power system are evaluated. After that, a multiple value model of energy storage applied in peak load shifting, smoothing renewable energy and improving power supply reliability is established. The use rate of devices, the static payback period and the profitability index are used as the system value evaluation indexes of the energy storage. Finally, Garver 6-bus test system is taken as an example to calculate the system value of the energy storage under different capacity configuration and verify the validity and effectiveness of the system value evaluation method proposed.
