Optimum placement of DGs with the aim of reducing losses and improving the voltage profile

Most of the share of losses in a power system is related to the distribution sector, which has always been considered. One of the important factors in increasing losses in the distribution network is the presence of reactive currents. The most common method of reactive power compensation in the power system is to use parallel capacitors. In addition to reducing losses, the advantages of capacitors include freeing up the capacity of the transmission network and improving the voltage profile. The issue of interest in capacitor placement is the optimal placement and evaluation of the capacitor in such a way that the profit from capacitor placement is maximized. Usually, the objective function in the existing optimal methods in the field of capacitors mostly includes reducing losses, improving the network voltage profile, or satisfying the two objectives mentioned together. The growing trend of exploiting distributed production units due to the many benefits of its use has caused the planners of the electricity industry in different countries of the world with different approaches to different aspects of exploitation as appropriate as possible from the investments made in this Study the field. Reducing the costs imposed on the electric energy supplier as well as the subscribers is one of the most important topics discussed in this field. In the meantime, categories such as reducing losses as a large share in operating costs and improving the quality of the voltage profile and voltage flashes as two main components in the quality of power delivered to the subscriber, directly and indirectly on the costs imposed on the company. Electricity and subscribers are influential.
