碩士 === 大同大學 === 電機工程學系(所) === 103 === Conservation voltage reduction (CVR) is a strategy that reduces the electrical demand of distribution feeder by lowering its operating voltage level. CVR has the benefits of reducing peak demand, energy consumption and carbon emission. Therefore, implementing CVR in Penghu island can help achieving the goal of constructing low carbon island in that area. Since the effect of CVR depends on the structure and the load characteristic of the feeder. This study will analyze the energy saving effect gotten from implementing CVR in Chongguang and Xiwei feeders of Penghu area. In addition to the assessment of overall energy saving effect of CVR, the cable loss, transformer copper loss and transformer core loss in the feeders under different operating voltage levels will also be examined in this study to understand the evolution of these losses when implementing CVR. Besides, since there are no downstream voltage control equipment in these feeders, this study will discuss whether better performance of CVR can be gotten when additional downstream voltage control equipments be installed and coordinated to perform CVR.
