Real-Time Digital Simulation of a PV solar system as STATCOM (PV-STATCOM) for voltage regulation and power factor correction.

This paper presents a real-time digital simulation study of a PV solar system as a STATCOM (PV-STATCOM) on RTDS (Real Time Digital Simulator) in a unique state-of-the-art research laboratory in a utility premise. This PV-STATCOM technology is utilized in the night for power factor correction and voltage regulation at the terminals of an induction motor operating at poor power factor. During daytime, the same objectives will be accomplished together with production of real power from solar insolation, by utilizing the inverter capacity remaining after real power generation. The local distribution company London Hydro is implementing this new technology, for the first time in Canada, on a 10 kW solar system to be installed on the rooftop of their headquarters building in Fall 2012. The proposed new control on PV solar system will help increase the utilization of the PV solar system, improve overall electrical system performance and provide a potential of additional revenue earning for solar farms for providing the above services, both during night and day.
