Determination of Maximum PV Integration Capacity for Distribution System

This paper is aimed to determine the maximum penetration levels of solar photovoltaic (PV) systems in distribution feeders to fully utilize the solar energy for a cleaner environment by taking into account the mutual coupling effect between phase conductors. The equivalent circuit models for distribution line segments including the grounding effect and the mutual coupling between phase conductors and the grounded neutral line are applied in the computer simulation. A practical Taipower distribution feeder is selected for system analysis to study the maximum PV penetration with the proposed precise modelling of the feeder network.
