Capacitor allocation in radial distribution system for maximal energy savings

Abstract

This paper presents a two-stage procedure to determine the optimal locations and sizes of capacitor in distribution network to achieve maximum energy savings. In first stage, loss sensitivity factor (LSF) is adopted to determine the optimal capacitor locations. Later stage, a new analytical approach is proposed to find the optimal capacitor sizes. The proposed method is implemented on well-known test cases such as 15-bus, 34-bus and 69-bus radial distribution networks. Besides the cost of energy savings, installation and operation costs have been considered in present investigation. The test results demonstrate the significance of the proposed method in energy savings compare to other methods as reported in literature survey. © 2016 IEEE.
