| With the high penetration of DGS in the distribution network and its impact on the power loss and voltage profile of the network, the choice of location and the optimal size of the DG has become a challenge for utility companies. In this paper, a method for determining the optimal location and size of dispatchable DG at different load levels for optimal utilization of the distribution network is presented. The goal is to reduce active power losses and improve voltage profiles for stable system performance. The average daily load demand is considered as the load demand profile. The optimal location of DG is determined by sensitivity analysis based on a new voltage stability index. The voltage stability index is based on the voltage breakdown feature and provides an overview of the network voltage stability so that it can show the effect of DG installation location on network voltage stability. DG provides loads at different levels, then by selecting the appropriate bus from the most important buses in terms of index, the optimal size of DG is determined using a search algorithm and based on the lowest active power losses for different load levels. The proposed method on IEEE 33 bus network has been tested using MATLAB software, and its results have been compared with other available methods. The results show the effectiveness of the proposed method in reducing active power losses and improving the voltage profile compared to other available methods. | ||
