Power loss minimization in distribution systems using multiple distributed generations

Abstract

In this work, an efficient analytical method is proposed for optimally allocating distributed generations (DGs) in electrical distribution systems to minimize power losses. The proposed analytical method can be employed for obtaining the optimal combination of different DG types in a distribution system for loss minimization. The validity of the proposed method is demonstrated using two test systems with different configurations by comparing with the exact optimal solution obtained from the exhaustive optimal power flow (OPF) algorithm. The calculated results and the comprehensive comparisons with existing methods prove the superiority of the proposed method in terms of accuracy and calculation speed. The proposed loss minimization method can be a useful tool for any general DG allocation problem since it provides effective and fast loss evaluation taking into account other benefits.

Operation and planning of distribution networks with integration of renewable distributed generators considering uncertainties: A review

“…In [192,193] both the optimal sizing and siting of DGs are determined by an analytical method to minimize the total power losses. In [194] an analytical method proposed to obtain the optimal combination of different DG types in a distribution system such as size, location and operating point in order to minimize the losses. This method applies in two test systems with different configurations by establishing a comparison with the exact optimal solution obtained from the exhaustive optimal power flow (OPF) algorithm.…”
