Abstract: | Reactive power optimization in power system can not only reduce power loss, but also improve voltage quality. So it is of great importance to security and economic operation of power system. Reactive optimization of power systems is a mixed optimizing question, which its operating variables include the continual and the separate, its solved process is quite complex, it is one component part of the optimal power flow problem. The paper discussed the modern artificial intelligent algorithms of reactive power optimization, summarized and analyzed the characteristics and usage situation of genetic algorithms. For improving the quality of the solutions and the calculation efficiency, the paper improved genetic algorithms, and applied to solve the reactive power optimization in power system |
