摘要：

Contingency screening and ranking is an important part of power system stability assessment. A contingency screening and ranking approach for receiving-end power grid with infeed HVDC is proposed. Firstly, a comprehensive evaluation index considering the transient voltage stability, the static voltage stability, the rotor angle stability, the characteristics of power flow transferring, and the support capability of power grid is constructed, which overcomes the limitation of single evaluation index. Secondly, combination of the analytical hierarchy process and the entropy weight method is used to determine the weight of each index with the experiences of power system operators and the objective information of index data. On this basis, the TOPSIS method is employed to rank the contingencies. Finally, numerical experiments on Hunan power grid with infeed UHVDC demonstrate the effectiveness and practicability of the proposed approach. © 2020, Power System Technology Press.
