4. ABSTRACT
This paper presents a novel concept of utilizing a photovoltaic (PV) solar farm inverter as
STATCOM, called PV-STATCOM, for improving stable power transfer limits of the interconnected
transmission system. The entire inverter rating of the PV solar farm, which remains dormant during
nighttime, is utilized with voltage and damping controls to enhance stable power transmission limits.
During daytime, the inverter capacity left after real power production is used to accomplish the
aforementioned objective. Transient stability studies are conducted on a realistic single machine
infinite bus power system having a midpoint located PV-STATCOM using EMTDC/PSCAD simulation
software. The PV-STATCOM improves the stable transmission limits substantially in the night and in
the day even while generating large amounts of real power. Power transfer increases are also
demonstrated in the same power system for: 1) two solar farms operating as PV-STATCOMs and 2) a
solar farm as PV-STATCOM and an inverter-based wind farm with similar STATCOM controls. This novel
utilization of a PV solar farm asset can thus improve power transmission limits which would have
otherwise required expensive additional equipment, such as series/shunt capacitors or separate
flexible ac transmission system controllers.
