Abstract
Load flow study is a numerical analysis of the power flow in interconnected power systems. This study is a fundamental aspect for the planning, operation, control and economic estimation of the power system. Newton Raphson (NR) method is the most successful method for solving the complex nonlinear power flow equations of the large power systems. The reliability of the solution obtained from the NR method is quite better than those obtained through other methods. Moreover, unlike other methods, it can also solve cases that lead to divergence. In this paper, the load flow analysis and distributed generation (DG) allocation in Indian utility 62-bus power system(real distribution system) is performed by using Backwards/ Forward Sweep (BFS) methods, NR method and combination of particle swarm optimization algorithm (PSO) with NR method. The solutions obtained using these methods were presented in terms of voltage magnitude, active power, reactive power, phase angle and power losses. The load flow solutions obtained using the above-said methods were validated with the results obtained using continuation power flow (CPF) and evolutionary-based optimal power flow (EPOPF) methods, published earlier. In this paper, the PSO algorithm is proposed for optimal placement, and sizing of DG with an objective of the power loss reduction and voltage profile improvement. PSO algorithm is used to find out the best location and optimal size of DG. © 2020, Research Trend. All rights reserved.
