Mahdi Mozaffari Legha, Mojtaba Jalali
This paper proposes Genetic Algorithm (GA) and Imperialism Competitive Algorithm for solving optimal distributed generation (DG) location and capacity. The objective is to minimize network power loss and improve the voltage stability index within the frame-work of system operation and security constraints in radial distribution systems. A detailed performance analysis is carried out on 33 bus system to demonstrate the effectiveness of the proposed methodology.
Two different objective functions are considered in this study: (1) minimization of active power loss (2) maximization of improve the voltage stability index. The goal is to optimize each objective function. The site and size of DG units are assumed as design variables. The results are discussed and compared with those of traditional distribution planning and also with Imperialism Competitive Algorithm (ICA) & Genetic Algorithm (GA).
