A Cost-Impact Analysis and Optimization of Realistic Grid Performance

Optimal placement and sizing of Distribution Generation (DG) in the grid resolves various problems namely, power loss, voltage profile improvement, enhanced reliability, and system stability. In this study, as a form of fact and realistic constraint, the positions of DG units in standard IEEE 30 bus networks were selected in advance for this study. An optimization technique called the African Vultures Optimizer Algorithm (AVOA) is suggested to determine the ideal sizes of these DG units as well as the best-linked buses with the DG units via transmission lines. The cases of two and three DG units fixed locations were the subjects of the suggested optimization technique. Both cases' costs and performances were examined while taking operating expenses into account. The results indicate that even after determining the ideal DG sizes and connected buses; the number of DGs still has a major impact on costs, losses, and performance. Furthermore, this study clarified that the optimization techniques can produce high performance at extremely high costs. The conclusion reached was that decision-makers should settle with nearly high performance at a fair cost.
