Minimizing harmonic voltage distortion with multiple current-constrained active power line conditioners

The purpose of this paper is to present a useful algorithm for minimizing harmomic voltage distortion levels Mirth multiple current-constrained active power line conditioners (APLCs) in a power system. The algorithm contains a sensitivity analysts-based single-APLC placement procedure and uses a nonlinear programming optimizer GRG2 to improve the solution if necessary. The usefulness of this algorithm is then illustrated by a distribution system example. Simulation results show that the algorithm is simple, computationally efficient, and can be easily extended to minimize several other alternative harmonic-related network objective functions.
