Recently, massive power outages in Europe and North America were caused by unbalances in reactive power, resulting in voltage collapse. In order to solve these problems in many advanced countries, voltage/reactive power control system developed for domestic power system and voltage/reactive power control system are operating. In terms of voltage stability voltage, Korea recognized the necessity of voltage/reactive power control system and developed hybrid intelligent voltage/reactive power control system using numerical algorithm based on the sensitivity matrix and intelligent technology. In this paper, voltage control rules of knowledge-base base on empirical knowledge of power system operator developed for managing the bus voltage efficiently voltage and the search method applied the least-cost search satisfying weighted evaluation function that newly applied through the continuous control quantity by applying the quantization process.
