Abstract: Due to the thermal energy storage（TES） and good operating characteristics, the concentrating solar power（CSP） plant is expected to become a black-start power source for emergency restoration of power system. Since the current pricing method for black-start service cannot fully arouse CSP plants’ enthusiasm to participate in system restoration, it is necessary to propose a new one which is suitable for the CSP plant. Considering the operation performance of the CSP plant acting as a black-start power source, with the aim of improving the storage level of TES to help accelerate the restoration of the power system when the potential blackout risk is high, this paper constructed a restoration effect based pricing model for black-start service. In this model, the equivalent unit capacity was introduced to measure the restoration effect of the CSP plant during system restoration, and the CSP plant was encouraged to prepare for black start by giving it recovery effect cost. Considering the influence of black-start service, a day-ahead Scheduling Optimization Model of the CSP plant was constructed, and the comprehensive evaluation index was put forward for reasonably pricing the black-start service. Finally, the New England 10-unit 39-bus power system was taken as an example to demonstrate the pricing process and verify the rationality and effectiveness of the proposed pricing strategy and method.
