Clustering Based Load Flow for Three Phase Unbalanced Distribution System with Voltage Sensitive Component Models

This paper presents a novel distribution power flow algorithm to estimate losses and analyze unbalanced distribution systems. An unbalanced distribution network is decomposed into clusters. The unbalanced laterals are solved using the backward/forward sweep method in each phase. The clustering of total network makes faster computation. The three phase modeling of all the distribution transforme...

Harmonic Elimination in Three-Phase Voltage Source Inverters by Particle Swarm Optimization

This paper presents accurate solutions for nonlinear transcendental equations of the selective harmonic elimination technique used in three-phase PWM inverters feeding the induction motor by particle swarm optimization (PSO). With the proposed approach, the required switching angles are computed efficiently to eliminate low order harmonics up to the 23 from the inverter voltage waveform, wherea...
