摘要：
The optimal control strategy of standing phase angle (SPA) considering the uncertainty of wind power output is of great practical significance to promote the safe and rapid restoration of high wind power penetration system. Firstly, the uncertainty of wind power output is represented by the cassette set, and the influence of the uncertainty on the SPA is analyzed with the interval power flow algorithm based on the direct optimization method. Then, by adjusting the output and terminal voltage of synchronous generators and restoring some load as the control measures, a two-stage robust optimization model is established to reduce the SPA. The aims of the model are to minimize the number of synchronous generators whose output is adjusted and the adjustment amount of these generators, and prioritize the restoration of important loads in order to ensure the reliability of the SPA. In order to solve the model efficiently, the linear-programming approximation of AC power flow is used to transform the original model into a mixed integer linear programming model, which is solved iteratively by the combination of the dichotomy method and the column-and-constraint generation method. Last, the numerical results verify the effectiveness and feasibility of the proposed model and method. © 2021, Power System Technology Press. All right reserved.
