基于改进Shapley值模型的风光储容量共享运营模式及收益分配研究OACHSSCD

The construction of a new power system urgently requires the collaborative development of wind power,photovoltaic power,and energy storage.However,the current collaborative development of wind-PV-storage is confronted with such problems as a low level of marketization,high risks in operational modes,and an imperfect benefit allocation mechanism.To address these issues,a wind-PV-storage capacity sharing operation mode was proposed based on the volatility and complementary relationship between wind and photovoltaic power outputs.An investment return function and economic evaluation indicators were established,and an improved Shapley value model was constructed by incorporating the risk-bearing factor,cooperation-contribution factor,and synergy-sharing factor.A case study in Jiangsu Province was conducted to perform simulation and benefit allocation analysis.The results indicate that the wind-PV-storage capacity sharing operation mode can improve the utilization rate of wind power and photovoltaic power,reduce the financial risks of wind and photovoltaic power generation enterprises,and enable capacity leasing to achieve better economic benefits under this mode.The application of the improved Shapley value model for benefit allocation increases the profit of shared energy storage operators by 25.2％.Multi-scenario analysis indicates that for shared energy storage operators,the net present value increases,the dynamic payback period shortens and the financial internal rate of return improves.Based on these findings,countermeasures and suggestions were put forward,including promoting the wind-PV-storage capacity sharing operation mode,optimizing the benefit allocation mechanism of shared energy storage,and facilitating the cross-regional energy storage capacity market transactions.The findings offer important references for formulating development strategies of shared energy storage and promoting the coordinated development of wind power,photovoltaic power,and energy storage.
