A Study of Load Flow Analysis Using Particle Swarm Optimization

Load flow study is done to determine the power system static states (voltage magnitudes and voltage angles) at\ud each bus to find the steady state working condition of a power system. It is important and most frequently carried\ud out study performed by power utilities for power system planning, optimization, operation and control. In\ud this project a Particle Swarm Optimization (PSO) is proposed to solve load flow problem under different loading/\ud contingency conditions for computing bus voltage magnitudes and angles of the power system. With the\ud increasing size of power system, this is very necessary to finding the solution to maximize the utilization of existing\ud system and to provide adequate voltage support. For this the good voltage profile is must. STATCOM, if\ud placed optimally can be effective in providing good voltage profile and in turn resulting into stable power system.\ud The study presents a hybrid particle swarm based methodology for solving load flow in electrical power\ud systems. Load flow is an electrical engineering well-known problem which provides the system status in the\ud steady-state and is required by several functions performed in power system control centers
