摘要

With the development of UHV (Ultra-High Voltage) transmission, great changes have occurred for the reactive power distribution. Especially the reactive power of UHV transmission varies with the different transmission power. Therefore, reactive power optimization considering penetration reactive power is presented in this paper. The estimation of the penetration reactive power is proposed in the paper. The optimization scheme can minimize the penetration reactive power of the UHV transmission and hence the voltage stability margin of the whole power system with UHV transmission. And the optimization is solved based on improved differential evolution algorithm. An example of Huadong power grid is discussed and analyzed. And it's proved that the present optimization control is effective and pratical.
