Voltage and reactive power control requires more advanced techniques along with rapid development of electric power needs. The basic theory of secondary voltage control was introduced, and an optimal secondary voltage control method was proposed. According to basic requirements of secondary voltage control, the mathematical model for dispersed secondary voltage control system was built up. An online searching based optimal algorithm was employed to deal with this co, ordinated control problem. Simulation results on a New England System show that the proposed secondary voltage control can effectively keep voltage level and enhance voltage stability.
