Operational Behavior of Line-Commutated Photovoltaic Systems on a Distribution Feeder

摘要

A study of the operational behavior of line-commutated inverter photovoltaic systems on a distribution feeder has been conducted using a detailed three-phase representation. This paper summarized and discussed the results obtained on the dynamic response of the photovoltaic systems to operating point changes, to load and line switchings, and to faults on the ac system. The paper also characterized the harmonics generated by such systems operating under unbalanced voltage and network impedance conditions, and examined the interaction between the inverter and the torsional modes of oscillations of nearby synchronous motor loads.
