An optimization algorithm for calculating optimal parameters of the third-order passive filter

摘要

An optimization problem of calculating optimal parameters of the third-order passive filter for centralized reduction of harmonic voltages in a radial network with distributed nonlinear loads is formulated. In order to solve the problem a two-stage algorithm is developed on the basis of particle swarm optimization and interior point techniques. The application of the suggested algorithm is exemplified by a real 220 kV network.
