摘要
Abstract
Cascading failure in power system is an extremely serious accident with low possibility, which may lead to the outage in a large area or even power system collapse. In order to prevent the occurrence of cascading failures and minimize its harm, the risk assessment indices of transmission system cascading failure is studied in this paper to guarantee the safe operation of power grid. In this paper, the risk assessment indices system of cascading failure of transmission system is proposed based on the complex network theory and risk assessment theory firstly. Then a simulation model of cascading failure is built based on the optimal power flow and each evaluation index is calculated. In the end, risk a-nalysis of cascading failure is carried out with an IEEE 118 test system as an example to verify the performance and effectiveness of the proposed method.关键词
