Renewable energy,primarily wind power and photovoltaics,has become significant sources of energy supply in China. To address the issues of wind power output’s volatility and intermittency,the concept of integrated wind power and storage co-generation is introduced with wind-solar storage co-generation plants as the central focus,mechanism and model of participation in inter-provincial spot electricity energy market clearing is studied. In an effort to enhance wind energy consumption and reduce wind and solar power wastage,conducting secondary clearing in addition to the primary clearing is suggested. Additionally,improving the existing method of penalizing wind and solar power abandonment by introducing the complementary variable wind and light abandonment penalty approach is proposed. Furthermore,priority is recommended to be given to the output of wind-solar storage co-generation plants over that of conventional thermal power units. Lastly,the proposed mechanism is simulated using the interconnected IEEE-39 node system to validate its effectiveness.
