Research Abstract

This study examined a voltage control for preventing a photovoltaic generator terminal voltage from deviating outside a normal operating range. It proposed to insert a series reactor into a service line and to switch unity power factor control to constant voltage control when the terminal voltage reaches a limit voltage. Effectiveness of the proposed methods was verified through numerical calculations and experiments.
