Turning distribution feeders into STATCOMs
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015Utilities implementing grid modernization programs, or facing challenges of increased level of renewable integration, are seeking tools that can provide distributed and dynamic volt-VAR control. This paper presents a distributed autonomous volt-VAR control approach that uses a large number of small rated VAR injection sources to convert a distribution ...

Coordinated Control of STATCOM and ULTC to Reduce Capacity of STATCOM
Electrical Engineering (ICEE), Iranian Conference on, 2018This paper presents a new scheme for coordination between ULTC and STATCOM. Both devices are commonly used to control the voltage and reactive power in network. The STATCOM, unlike ULTC is characterized by its fast response so capable of dynamic voltage control and also providing reactive power in emergency situations.

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 ...

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

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
