The concepts and research approaches of hybrid control systems are applied into the voltage control of power systems in the paper, and a solution based on hybrid automatic voltage control is proposed to the Northeast China Power Grid. The solution is able to improve the Northeast China Power Grid's dynamic performance and voltage stability, and meanwhile reduce the grid's operation losses through rational dispatching the reactive power. In the solution, a hybrid layered voltage control model is set up, the discrete events are taken as drives of the system, and synthetic objects of voltage control are achieved. These methods contribute to better feasibility of the solution, which provides easier access to optimizing solutions and higher calculating efficiency by fully using the technologies available. Results of computer simulation have proved the solution effective in realizing automatic voltage control.
