电力系统恢复后期网架重构和负荷恢复的两阶段优化方法
Two-stage Optimization Method for Network and Load Recovery During Power System Restoration
摘要
Abstract
ABSTRACT:Network and load recovery (NLR) during power system restoration is a complex mixed-integer nonlinear optimization problem, which is difficult to be solved efficiently. To reduce the difficulty and improve the efficiency, this paper proposes a two-stage optimization method to decouple the NLR into a mixed-integer linear optimization problem and a continuous nonlinear optimization problem. In the first stage, the optimal plan for transmission line charging and load pick-ups is determined by mixed-integer linear programming (MILP) based on the DC power flow with frequency characteristics. Then in the second stage, an expanded AC power flow based continuous nonlinear optimization model is established to minimize the recovery time based on the optimal plan determined in the first stage. The 10-machine 39-bus system is used to analyze the efficiency and characteristics of a restoration plan in both single step and whole restoration process. Analysis results reveal that the restoration plans obtained from the proposed method are more efficient than those obtained by heuristic algorithms, while computation time is greatly reduced. Finally, the feasibility of applying the proposed method in a real power grid is validated through the Hubei Southeast Power Grid.关键词
