| 摘 要： | 爬坡事件是风电功率在短时间内发生大幅变化的事件，严重威胁着电力系统的安全稳定经济运行，研究有效的爬坡控制策略迫在眉睫。基于场群互补性评价指标，以场群偏差最小和各风电场可以获得更大的收益为目标，提出考虑辅助服务补偿费用的合作博弈风电爬坡控制策略。分别以风电场出力和出力调整量、风电场实际出力和计划值的偏差构建支付函数，促使风电场采取合作博弈方式，更好地完成场群计划，减少所需缴纳的辅助服务补偿费用，提高自身利益和整体利益。仿真结果表明，所提合作博弈爬坡控制策略可以在发生爬坡事件时提高各风电场和整体的利益，提高场群计划的完成度。

| Abstract: | Ramping events, during which the wind power greatly changes over a short period of time, seriously threaten the safe and stable economic operation of wind power systems. It is extremely urgent to study an effective ramping control strategy. Based on the field group complementarity evaluation index, and aiming at minimizing the field group deviation and increasing the profitability of each wind farm, a cooperative game based ramping control strategy for wind power is proposed considering auxiliary service compensation cost. The payment function is constructed based on the wind farm output and output adjustment and the deviation between the actual output and planned output, which encourages the wind farm to adopt a cooperative game mode. Cooperation helps the wind farm and its group better complete the field group plan, reduce the compensation fees for auxiliary services, and improve the interests of both the individual farm and the overall group. The simulation results show that the proposed cooperative game based ramping control strategy can improve the interests of each wind farm and the whole group when ramping events occur, and also can improve the completion degree of the field group plan. |
