This paper presents a search strategy to identify the chains of events that may lead to cascading failures in power systems. The genetic algorithm is applied to implement the search strategy in accordance with a proposed combined risk index incorporating severity and probability of contingency information. The system frequency characteristics are taken into account as well during analysis. Finally,...
A new bi-level programming model of multistage transmission network expansion planning (TNEP) based on double-bidding based pool electricity market is presented in the paper. Open access transmission brings new challenges to transmission planning. From the transmission company's view, the goal of optimal transmission planning scheme should not only bring the optimal transmission profit in the market,...
Using traditional genetic algorithm (GA) to solve distribution network reconfiguration, the required radial network structure can not be ensured and a large number of infeasible solutions are brought about. Although some improved methods were put forward, they either are of computational complexity or can not completely settle the problem. In this paper, the strategy of searching randomly spanning...
