This paper introduces at) integrated control strategy based on hybrid control theory for the control of voltage and reactive power in power system substations. The strategy adopts a hierarchical, multilayer Structure to achieve a multi-objective optimization of voltage and reactive power control and improves the traditional "nine-area diagram" control method. The new hybrid control strategy not only solves the problem of oscillatory responses caused by the changes of the on-load tap changer (OLTC) taps and switching the shunt capacitors, but also responds to the global optimal control commands of voltage and reactive power from the master station with good steady-state responses. The hybrid automatic voltage control (HAVC) strategy is tested via simulation of the Northeast China 500 kV grid and the results demonstrate the effectiveness of the strategy.
