Abstract

This paper proposes distribution-unified power flow controller (D-UPFC) in the distribution system. D-UPFC controls distribution system voltage during voltage sags and swells. A single-phase ac-ac converter in a matrix arrangement and a series transformer are the components of D-UPFC. Ac-ac converter generates power using switching pattern when voltage variation occurs. The series transformer compensates voltage to the loads. Voltage swell condition is considered when reverse power flows from the clustered photovoltaic (PV) system. D-UPFC simulations show the possibility of controlling distribution system voltage when voltage sags and swells occur
