摘要：
Reactive power compensation plays a significant role in reducing the line of the power grid and improving fault handling ability and stability. As a consequence, this paper aims at the transmission N-1 fault and the dominant fault of the power grid under limited economic constraints based on the electrical intermediary model of the grid topology. Considering the economic constraints of reactive power compensation and the constraints of power flow equations, the optimal object is combined with the minimum generation cost, the loss of network and the optimal margin, in order to explore the dominant line fault conditions optimal compensation strategy. Finally, due to its complexity of the mixed- integer nonlinear model and hard for convex relaxation, the adaptive genetic algorithm of the improved elite strategy is uesd to solve the problem. Simulation on the IEEE-14 node system validates the effectiveness and feasibility of the proposed algorithm. © 2019, Editorial Office of Control and Decision. All right reserved.
