Study On Improved Secondary Voltage Control Based On Genetic Algorithm

Voltage Hierarchical Control is an efficient way to coordinate the voltage control in the power system, and the control strategy for the Secondary Voltage Control is the critical part of the Voltage Hierarchical Control.Because the control devices of the secondary voltage control have devices of continuous regulation and discrete regulation, the improved optimization model for secondary voltage control has been built firstly in this paper, and genetic algorithm is applied to solve the model. An improved method is brought forward to solve the two problems existing in the adjustment process which are voltage jump and long regulation time. Then the research on the network equivalence applied in the secondary voltage control is also made preliminarily. Lastly the improved secondary voltage control management in system contingencies is investigated in this paper.
