PSO-Based Three Phase Optimal Power Flow

This paper presents a method of finding the optimal operating point minimizing a given objective function with three phase power flow equations and operational constraints, called 3 phase optimal power flow. Three phase optimal power flow can provide operation and control strategies for the distribution systems with distributed generation assets, which might be frequently in unbalanced conditions assuming that high penetration rate of renewable energy sources in the systems. As the solution technique, this paper adopts a standard particle swarm optimization (PSO).
