Wind-photovoltaic Hybrid Power System is an open distributed system. It is suitable to make decision and control dispersedly with multi-agent technology. According to the relation between voltage and reactive and active power, a voltage reactive optimization control model considering voltage stability with the least active power loss as objective is constructed, and an advanced Particle Swarm Optimization based on Uniform Design and Inertia Mutation is proposed to solve this model. In order to control voltage automatically, an automata model of voltage control system is made. The results of simulation experiments show that the voltage optimization control model and the advanced Particle Swarm Optimization are effective to voltage reactive power optimization control and the automata model of voltage control system can track the variety of voltage in time and control voltage automatically.
