Novel nighttime application of PV solar farms as STATCOM (PV-STATCOM)
2012 IEEE Power and Energy Society General Meeting, 2012Photovoltaic solar farms generate power only during daytime and remain completely idle during the nights. This paper presents a novel technology of utilizing Photovoltaic (PV) Solar Farms in the nighttime. New controls are developed for the solar farm inverters to operate as STATCOM - a Flexible AC Transmission System (FACTS) Controller, using the ...

2008 IEEE Power Electronics Specialists Conference, 2008
Dynamic VAR support is essential for grid support, particularly to help ride-through significant faults on the system. Conventional sources of VARs, such as capacitor banks and generators, respond too slowly to have the desired impact. Static VAR compensators (SVC) are faster, responding in 1/2 to 1 cycle, but offer reduced VAR support under fault ...

Quadratic Linearization of STATCOM
2018 IEEE 8th Power India International Conference (PIICON), 2018Control of STATCOM is important for the stability of power system to which it is connected. Since STATCOM dynamics is nonlinear, various control strategies have been proposed including feedback linearization which involves internal dynamics. In this paper, we propose to quadratic linearize the STATCOM equations and the problem of internal dynamics does

PV Solar System Control as STATCOM (PV-STATCOM) for Power Oscillation Damping
IEEE Transactions on Sustainable Energy, 2019This paper presents a novel control of photovoltaic (PV) solar system as a FACTS device STATCOM, termed PV-STATCOM, for power oscillation damping (POD) in transmission systems. In the proposed control, as soon as power oscillations due to a system disturbance are detected, the solar farm discontinues its real power generation function very briefly (few
