Abstract

In order to develop an estimate of the benefits of Conservation Voltage Reduction (CVR) in the distribution system, composite characteristics of system loads based on ZIP modeling has been extracted from measurements of electrical quantities at the main substation. This knowledge is further used in finding a quantitative estimation approach for predicting the effectiveness of substation transformer tap changes in reducing total power demand in different load conditions. The proposed algorithm is implemented on the IEEE 34 bus test system and the results are demonstrated. It is shown that the method can predict the effectiveness of CVR with acceptable accuracy.
