In recent years, it has been very important to adequately keep power qualities such as voltage and imbalance and so on. Especially the imbalance of voltage on distribution system may increase in the future by increasing electrified houses. Therefore it is necessary to decrease imbalance of voltage all the time in cooperation with electric power company and consumers. The high voltage consumers usually install static capacitors (SC) in order to improve power factor at receiving point. In this paper authors propose the method that these SCs in consumers are controlled in order to decrease the imbalance of voltage on distribution line. By the proposed method, single phase SCs are installed and the amounts of these SCs are decided in cooperation with several consumers that the proposed method is installed. The effect of the proposed method is confirmed by numerical simulation. Furthermore the effective scheme for introducing the proposed method to consumers is studied in this paper.
