Optimal power flow and interline power flow controllers using particle swarm optimization technique

This paper presents an optimal power flow control in an electrical power system incorporating interline power flow controller (IPFC) and using the particle swarm optimization (PSO) technique. Based on the steady state model, the sizing of the IPFC controller in the network is formulated as an optimization problem to minimize the transmission line loss in the network. The power flow control constraints due to the use IPFC is included in optimal power flow (OPF) problem in addition to the normal conventional constraints.
