Optimal Placement of Distributed Generation for Power Quality Improvement using Hybrid ABC-CS Algorithm

Distribution generation (DG) is a term that refers to the production of electricity near the consumption place. On a local basis, there are opportunities for electric utilities to use DG to reduce peak loads, provide auxiliary services such as reactive power and voltage support, and improve power quality. In many cases, distributed generators can provide lower-cost electricity and higher power reliability and security with fewer environmental consequences. Hence, the Dg is placed in the power system to reduce the power loss and increase the power quality. This paper presents a new hybrid optimization algorithm to determine the optimal DG location and size to minimize the total power loss, total harmonic distortion (THD), and voltage sag index improvement. The proposed hybrid optimization algorithm combines the behavior of the Artificial Bee Colony and Cuckoo Search (ABC-CS) algorithm. The DG units are optimally placed by considering the objectives like voltage profile and power loss. The implementation results suggest that the proposed system for the DG placement produces better performance, so that power system quality can be achieved.
