摘　　要：为适应电力系统不确定性程度增强的背景,在调度中充分发挥频率调节效应的作用,从新的视角给出了电力系统运行协同的经济调度思路。依据自动发电控制技术,在不考虑电压变化影响的前提下,将协同能力的定义划分为三类,即自动的协同能力、可控的协同能力和再可控的协同能力。与此相适应,在与调度紧密结合的前提下,又给出调度所面临自动的协同状态、可控的协同状态、再可控的协同状态的三状态概念。在此基础上,提出电力系统运行协同的经济调度模型。该模型将频率纳入决策中,针对不可控源波动预期,在模型中有效计及三状态所对应的约束,并给出予以解决的优化方法。最后通过10机算例系统,验证了所提方法在不确定性情景下,增强电力系统源平衡能力的有效性。To adapt to the background of increasing uncertainty in power system and make full use of the frequency regulation effect in dispatch, the idea for synergetic economic dispatch was given from a new perspective. Based on automatic generation control, the synergy ability was divided into three types without considering the influence of voltage change, namely automatic synergy ability, controllable synergy ability and re-controllable synergy ability. Accordingly, on the premise of closely integrated with dispatch, three dispatch states dispatch were introduced, namely automatic synergy state, controllable synergy state and re-controllable synergy state. Based on these, the model of synergetic economic dispatch in power system operation was established. Frequency was seen as a decision variable in this model, and the constraints which correspond to the fluctuating expectation of uncontrollable sources for each state were all considered, and the optimization method to solve this problem was given. In the end, a 10-machine system was used to verify the validity of the proposed approach that it can enhance the ability of power system to keep source power balance under uncertainty.
