Distribution harmonic state estimation based on a modified PSO considering parameters uncertainty
This paper presents a new algorithm based on a Modified Particle Swarm Optimization
(MPSO) to estimate the harmonic state variables in a distribution networks. The proposed
algorithm performs the estimation for both amplitude and phase of each injection harmonic
currents by minimizing the error between the measured values from Phasor Measurement
Units (PMUs) and the values computed from the estimated parameters during the estimation
process. The proposed algorithm can take into account the uncertainty of the harmonic …
