Reconfiguration smart distribution networks with the aim of loss reduction and voltage stability enhancement in the presence of D-STATCOM

Distribution of distribution network and use of D-STATCOM are two conventional methods to reduce losses and improve voltage stability in the distribution network that must be done optimally to bring more benefits to the distribution network. The purpose of this paper is to determine the optimal distribution network arrangement in the presence of D-STATCOM. To solve the problem of rearrangement of the distribution network along with determining the capacity and installation location of D-STATCOM, the propeller algorithm (GOA) along with multi-objective weighted method with the objective of reducing losses and improving voltage stability has been used. The proposed method is simulated on two IEEE standard 33 and 69 bus tests. Three different scenarios were considered for the simulation, which are the presence of D-STATCOM only in the distribution network, rearrangement of the only distribution network and rearrangement of the distribution network with the presence of D-STATCOM and the results of the proposed method will be compared with PSO algorithm.
