PSO-Based Distributed Generation Planning

Various benefits of distributed generator (DG) units are thought to improve the distribution power grid's safety. However, profits can be enhanced by assuring optimal DG unit sizing and positioning, as arbitrary DG unit placement can negatively impact and imperil power systems, contributing to increased power loss and voltage profile degradation. As a result, numerous ways to ensure the optimal size and position of DGs have been proposed. The fundamental goal of this paper is to develop a method for optimum DG scheduling and operation in order to improve voltage profile, reduce power loss and to improve overall network reliability. To diminish power losses (PL) and improve the voltage profile (VP), PSO is used to discover the ideal site and size of DG. The IEEE 33 distribution system is used in this work to demonstrate the applicability of PSO. The performance of DG based on proposed PSO based algorithm is compared with the existing techniques. Finally, the findings reveal that the PSO outperforms the NR method as bus no. 19 is found to be the preferred location for minimum losses (0.000043 pu) and improved voltage profile (0.00166).
