Power Network Decomposition with New Ant Colony Optimization

In this paper, a new method is proposed for power network decomposition. The proposed method is based on ant colony optimization (ACO) that is one of meta-heuristics. In recent years, power systems become more complicated due to the emergence of the deregulated power market. As a result, there is a trend that the decentralized control scheme should be implemented to smooth power system operation and control. This paper proposes an efficient power network decomposition method to realize decentralized voltage and reactive power control with ACO. It is base on swarm intelligence that a set of agents evaluates better solutions. The heuristics of node connections is introduced into the ACO algorithms. The proposed method is successfully applied to the IEEE 118-node system
