Abstract
Voltage dips may cause adverse effects to connected devices. Series and shunt grid-connected converters have been developed to compensate voltage amplitude variations. However, existing compensation approaches either rely on information of load current or external reactive power reference. In this paper, a voltage dip compensation strategy, which requires local measurements only, is proposed. This approach enables mainstream shunt grid-connected converters, which have no external current sensors, to compensate voltage dips (and swells) in distribution grids. A converter prototype is built and tested to verify the proposed compensation strategy.
