A Study on The Optimal Search Method of The Hybrid Intelligent Voltage/Reactive Power Control System

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.
