Abstract


Objectives: This paper presents a two stage solution strategy to solve multi objective optimization problem in the presence of Distributed Generators (DG) in planning a primary distribution system. Methods/Statistical Analysis: Using this, the economical aspects such as net savings and the technical aspects such as voltage deviation and section current index objectives are optimized while satisfying system equality and in-equality constraints. The optimum number of DGs and its optimal locations are identified in a given system so as to enhance the system security by minimizing the system power losses. The proposed methodology uses fuzzy decision approach to select the best compromised solution from the total generation Pareto solution as per the operators' requirement. Findings: According to the analytical results, the proposed framework in the presence of DGs enhances the system performance more effectively. Application/Improvements: The feasibility and effectiveness of the proposed method are examined on standard 15-node, 33-node and 69-node test systems.

Keywords
