Abstract

The optimal control of voltage and reactive power is one of the essential issues for power grids´ security and the economical operation. Having elaborated the model of reactive power optimization in regional power grids, this paper advances an improved genetic algorithm integrated with reduced gradient technique for solving of ORP problem in regional power networks. It is implemented repeatedly on IEEE 30-bus system and an actual regional power grid. Compared with several other algorithms, the testing results demonstrate its effectiveness. It is showed that the proposed hybrid algorithm can gain better voltage profile and less active power loss simultaneously within permissible limits.
