摘　　要：随着风电等间歇式能源并网,自动发电控制(AGC)过程中将出现越来越多的区域间功率支援,而各区域都不愿付出过多的调节代价,如机组磨损、额外燃料消耗、偏离经济调度下的运行点造成的损失。解决其间的博弈困局,制定有说服力、稳定的协调运行方案,是调动全网调频资源共同消纳间歇式能源的前提。文中利用微分博弈理论对该问题进行建模并求解,使博弈达到非合作反馈纳什均衡点。在两区域AGC模型上的仿真结果显示,与比例—积分控制和最优控制不同,所提的协调控制策略能保证被各区域自愿、忠实地执行,因为单独改变策略将导致收益下降。With intermittent energy connected to the power grid,such as wind,power support between different areas in the process of automatic generation control （AGC） is ever increasing.However,no area is willing to pay too much for its regulation costs,such as the wear and tear of units,the extra fuel consumption,the loss caused by the deviation from the operating point of economic dispatch,etc.The solution of this game and a convincing and stable plan for coordinated operation are the preconditions for accommodating intermittent energy by frequency control resources in all areas.This paper models and resolves the problem using the differential games theory to provide the noncooperative feedback Nash equilibrium.The simulation results on a two-area AGC system show that,unlike the proportional-integral （PI） control and optimal control,both areas voluntarily and faithfully implement the proposed coordinated control plan since an individual change of the strategy will lead to a decline in revenue.
