A bilevel programming model for the reactive power optimization

A new bilevel programming model combined the reactive power optimization and the voltage stability is presented in this paper. A hybrid algorithm, based on the genetic algorithm and simulated annealing algorithm to solve this bilevel programming model of the reactive power optimization, is constructed. Testing results of applying the algorithm to an IEEE-30 bus system and an IEEE-6 bus system shows feasibility and efficiency of algorithm. Consequently, blind adjustment of local voltage in nowadays electric power system is solved effectively, at the same time, the dispatch center adjusts and controls the voltage level of bus and active power losses successfully
