Research on reactive power optimization of regional power system based on immune genetic algorithm

Voltage optimization adjustment and management is the basic measures to ensure the voltage quality of power grid and to realize the important means of economic operation of the system. In the operation of the power system, because of the difference of each substation load level and load properties, led to a part of the substation reactive power capacity is insufficient and the other part of reactive power is excessive. It is easy to cause that system voltage is too low or too high, the voltage qualified rate and, the stable and economic operation of power system are affected. In this paper, a new reactive power optimization method is made based on immune genetic algorithm in regional power system, which could reduce system reactive power loss as well as keep the voltage qualified.
