This paper presents a novel control of 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 tens of seconds) and makes its entire inverter capacity available to operate as a STATCOM for POD. As soon as power oscillations are damped, the solar farm restores real power output to its pre-disturbance level in a ramped manner, while keeping the damping function activated. This results in much faster restoration than that specified in grid codes. During nighttime, the solar farm performs POD with its entire inverter capacity. The proposed PV-STATCOM is about 50-100 times cheaper than an equivalent STATCOM for providing POD at the same location. This novel control can potentially bring large savings for transmission utilities and open up a new revenue making opportunity for solar farms for providing POD. Fuzzy logic controller based statcom produce better enhancement in power oscillation damping. Results are verify through MATLAB/SIMULINK software.
KEYWORDS
Flexible AC Transmission Systems (FACTS), particularly the Static Synchronous Compensator(STATCOM), are widely used to improve the stability and overall performance of power systems. In this work, a photovoltaic-based STATCOM (PV-STATCOM) integrated with a Fuzzy Logic Controller (FLC) is proposed to reduce power oscillations effectively. The proposed approach operates by temporarily suspending the real power generation of the PV system during grid disturbances in daytime. When oscillations occur, the PV inverter stops supplying active power for a short duration and instead utilizes its full capacity to provide reactive power support for damping oscillations.
