The study on improved genetic algorithm´s application in under voltage load shedding

Under voltage load shedding is an important method of emergency voltage control, according to the realization it can be divided into two ways, centralized and distributed. This paper proposed a centralized algorithm based on the improved genetic algorithm. First, an optimization model for the purpose of stabilizing voltage was established, and genetic algorithm is used to solve this problem, the genetic algorithm was improved by the means of real number encoding. Simulation results show that this algorithm can stabilize voltage with a small cost.
