DG Allocation in Power Systems for Voltage Profile and Power Loss Improvement

Abstract

The Distribution system face the problem of Power Loss and Voltage drop. The Power Losses and Voltage Drop can be minimized by optimal allocation of Distributed Generators (DGs) in the distribution network. Therefore, this thesis analyzes the deployment of DGs in distribution systems with an objective to simultaneously reduce Active Power Loss, Reactive Power Loss and Voltage Drop. A post deployment economic assessment is done to determine the profitability of positioning DGs in the distribution network. Battle Royale Optimization (BRO) algorithm is proposed in this thesis to find optimal location of DGs. The results of the proposed BRO algorithm are compared with Artificial Bee Colony (ABC) and Genetic Algorithm (GA). Newton Raphson load flow analysis with the suggested BRO algorithm is conducted on IEEE 33 and 69 bus radial distribution system. Fifteen test cases consisting of different stages have been formed and investigated. Single, Multiple and Hybrid combination of DGs is considered in different stages. The results prove that hybrid combination of DGs substantially reduce the Power Losses and Voltage drops.
