Abstract | Some buses in a power system feed power to loads that are sources of harmonics. This type of bus is called a complex-bus. This paper provides a new application of the constrained least absolute value algorithm (LAV) to identify the type of harmonics loads on a complex bus and their harmonics contribution to the main bus current. The problem is first formulated as a least error squares (LES) constrained parameter estimation problem using LaGrange multiplier to adjoin the equality constraints. To this stage the equality constrained is used to sum the contribution from each load at certain harmonic frequency. The LAV technique is used to solve the resulting problem. Computational results are given for actual recorded data. |
