| Abstract |
In this paper, the CVR estimation method is proposed using the direct method. This method calculates the voltage change and the load change for the same time period when the tap of a main transformer in a substation changes. Through these CVR estimation results, economic analysis is conducted by analying the CVR effect of the domestic distribution systems. Based on the estimated CVR factor, a representative model of the domestic distribution system is assumed, and economic analysis is evaluated through CVR effect analysis when CVR control is operated. Demand reduction of a substation and line loss reduction costs are calculated using the CVR factor and voltage reduction. Through this analysis, CVR in distribution systems can be expected to reduce the power loss cost and power plant construction cost. |
