Abstract—This paper presents a novel concept of utilizing PV

solar farm inverter as STATCOM, termed PV-STATCOM, for

improving stable power transfer limits of the interconnected

transmission system. The entire inverter rating of PV solar

farm which remains dormant in the 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 above

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 also in the

day even while generating large amounts of real power. Power

transfer increases are also demonstrated in the same power

system for i) two solar farms operating as PV-STATCOMs

and ii) a solar farm as PV-STATCOM and an inverter based

wind farm with similar STATCOM controls. This novel

utilization of 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

(FACTS) Controllers.
