%X Voltage and reactive power control for a substation is an important part of the power grid hybrid automatic voltage control(HAVC) system. In substations, on-load tap changer(OLTC), shunt capacitors and reactors are widely used as control measures. The design of voltage and reactive power controller in substations is a typical multiobjective optimal problem. That is, the voltage of the secondary bus should trace the desired value as closely as possible, and the number of regulations of OLTC and capacitors should be minimized to protect the equipment. In this paper, a multiobjective optimal model for substation voltage and reactive power control system is built, and the corresponding algorithm is proposed. Based on this algorithm, a multi-objective optimal control strategy of substation HAVC system is designed. The simulation results of Shaling substation in Northeast China demonstrate the effectiveness and correctness of this strategy.
