Power Quality Analysis of Electric Transportation on Distribution Systems

This paper studies the power quality analysis of electric buses (EBs) and electric vehicles (EVs) on the distribution system. The stochastic harmonic models for EBs and EVs and the stochastic models for their usage scenarios are built considering the uncertainties of the measured data. Based on these models, this paper proposes a harmonic load flow analysis considering the uncertainties of system and measured data. The Monte Carlo Simulation is used to discuss harmonic current and voltage of distribution systems caused by EBs and EVs. An actual power distribution system of TaiPower is taken as an example to validate the practicability of the method proposed in this paper.
