Study And Development Of Regional Power Grid Reactive Power Optimization System

This paper designs and develops the area network reactive power optimization system.Reactive power optimization is a large scale nonlinear optimization problem with a large number of variables and terms.According to these characteristics,a new algorithm of the chaos ant colony optimization(CACO) has been presented to use in reactive power optimization system.This paper makes a summary of reactive power optimization.Then,this paper reviews recent work on ant algorithms and applications.Ant colony optimization algorithm is a new kind of simulated evolutionary algorithm.The test result shows that ant colony optimization algorithm can well solve nonlinear problems.This article will be introduced chaotic sequence of the ant colony algorithm,to improve the ant colony algorithm.Finally,the chaos ant colony optimization(CACO) algorithm is designed and used in reactive power optimization system.The model of reactive power optimization is established taking the minimum network losses as the objective.Its validity is verified through arithmetic examples of IEEE30 node and a practical area network.
