Application of virus particle swarm optimization algorithm in economic operation of hydropower station

The virus particle swarm optimization algorithm (VPSO), which integrates the virus evolutionary mechanism into the particle swarm algorithm (PSO), is presented in this paper. Host population and virus population are generated during the evolution. The former transmits genetic information between the different generations which is the same as PSO and the latter carries out the infection operation in the same generation through transcription and reverse transcription. VPSO can effectively inhibit the “premature” phenomenon of particle and accelerate the speed of convergence. A case study is adopted to show that the VPSO algorithm can provide a new way to solve the economic operation of power system.
