中文摘要:

      以风电、光伏为主的可再生能源已成为中国重要的能源供应形式。为解决风光出力的波动性和间歇性问题，提出风光储一体化联合发电的概念。以风光储联合发电站为主体，研究其参与省间现货电能量市场出清的机制与模型。为提高风光消纳能力，减少弃风弃光现象的发生，提出在一次出清的基础上进行二次出清，改进已有的弃风弃光分段惩罚方法为互补变量式弃风弃光惩罚方法，设置风光储联合发电站出力优先级高于普通火电机组。最后基于互联的IEEE-39节点系统对所提机制进行仿真模拟，验证其有效性。

英文摘要:

      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.
