Concentrating Solar Power Plant Configuration Method of Renewable Energy Base with Consideration of Confidence Capacity and Peak Shaving Capcity
The concentrating solar power plant(CSPP)has the friendly grid-connected characteristics of clean,low carbon and long-term energy storage,which can effectively smooth the fluctuation of renewable energy output.Compared with the traditional thermal power unit,the adjustment ability of CSPP is still insufficient,which may reduce the delivery capacity of renewable energy base.Thus a confidence capacity and peak shaving capacity evaluation method and model based on equal power output reliability before and after CSPP access is proposed.On this basis,with the goal of power generation economy of the renewable energy base,the model considering the constraints of the unit,the delivery constraints,the confidence capacity and the peak load capacity of CSPP is also established.Based on the time series simulation technology,the optimal configuration model of heat storage duration and capacity of CSPP is solved.The configuration scheme of CSPP under typical scenarios is given,the economic comparisons under different wind and solar ratios are analyzed,and the optimal ratio scheme is obtained.The thermal storage duration and capacity allocation method proposed in this paper can effectively improve the low carbon nature of the renewable energy base and optimize the investment return of CSPP.
