  Although DIG and shunt capacitor are very useful for the distribution system, but to maximize the obtained benefit from the system, placement of these devices at optimal location with appropriate size is very much necessary to get the highest benefit from the devices. In this regard, this paper proposes  the optimal deployment of DIG and shunt capacitor in a 33-bus radial distribution system to overcome line losses and increase the financial benefit of the distribution system owner.  Different indexes such as Cost Index (CI), Active loss reduction index (ALRI), and Reactive loss reduction index (RLRI) are proposed and formulated accordingly. Different cases are considered and the obtained results are deeply analyzed for finding out the best option of system operator. After a detail introduction in Section 1 of the manuscript, Section 2 presents the modeling of DIG and shunt capacitor. The objective functions of this study are discussed in Section 3. Section 4 represents...

  As a result, there have been a more active power and reactive power loss in the distribution system and accordingly, the end customers will face voltage drop and there is a high possibility that the voltage magnitude on most buses may be below the minimum voltage limit i.e. 0.95 P.U. In such situation, there has been a constant load growth among different customers in recent years and this will worsen the voltage magnitude in the forthcoming years, which will reduce the power system stability margin [4]-[6]. Therefore, the active and reactive power sources must be integrated in the system to improve the voltage magnitude so that the power stability margin can be improved. For that reason, the system planning engineers are focusing nowadays on the incorporation of distributed generation (DIG) and shunt capacitor so that a secure and stable operation of power system can be achieved.   DIG is the local source of electricity that is situated at a close distance of the custo...

  ABSTRACT   In this study, to keep the secure and stable operation of the power system, distributed generation (DIG) and shunt capacitor are optimally placed in a radial distribution system. Many researchers are working on optimal DIG and shunt capacitor placement using intelligent method like genetic algorithm, artificial neural network, fuzzy logic and ant colony algorithm. In such regard, a particle swarm optimization (PSO) based technique is used to determine the optimal location and optimal size of the DIG and shunt capacitor. The main purpose of this study is to increase the economic advantage of the distribution system operator as well as to decrease the active and reactive power loss. Different indexes such as Cost Index (CI), Active loss reduction index (ALRI), and Reactive loss reduction index (RLRI) are proposed and formulated accordingly. Different cases are considered and the obtained results are deeply analyzed for finding out the best option of system opera...
