【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。
[Abstract]:In order to adapt to the background of increasing uncertainty of power system and give full play to the effect of frequency regulation in dispatching, the economic dispatching idea of power system operation cooperation is given from a new perspective. According to the automatic generation control technology, the definition of synergy is divided into three categories without considering the influence of voltage change, that is, automatic synergy, controllable synergy and recontrollable synergy. In order to adapt to this, on the premise of close combination with scheduling, the concepts of automatic cooperative state, controllable cooperative state and controllable cooperative state are given. On this basis, an economic dispatching model of power system operation cooperation is proposed. In this model, the frequency is brought into the decision, and the constraints corresponding to the three states are effectively taken into account in the model for the expectation of uncontrollable source fluctuation, and the optimization method is given to solve the problem. Finally, the effectiveness of the proposed method to enhance the source balance capacity of power system under uncertain scenarios is verified by a 10-computer example system.
