Optimal Sizing and Placement of DG Units in Radial Distribution System Using Cuckoo Search Algorithm

摘要

Due to the evolution of interconnected power systems, the loss reduction in distribution systems has become a subject of major concern. Integration of distributed generation units which are based on renewable energy, provide potential benefits to conventional distribution systems while considering environmental impact. Practice of insertion of DG units in the distribution network system has increased drastically in the recent years because of multidimensional advantages of DG units. It includes the minimization of power loss in network, sharp improvement of bus voltages profile, improvement of reliability and power quality of system. The main objective of this paper is to demonstrate a simple technique to determine appropriate location and size of distributed generation units in the distribution networks in order to reduce real power losses of system. Cuckoo Search Algorithm (CSA) is used as an optimization technique and is implemented on standard IEEE-33 bus radial distribution system to demonstrate the effectiveness of proposed methodology.
