Stability Characteristics of Photovoltaic System Using SVC Controllers

In the present era, solar photovoltaic of renewable power generation has helped human mankind owing to the depletion of fossil fuels for the power generation. Due to the intermittent nature of solar power, many problems are faced by operators during the power generation. This research work proposes a new methodology to control the operating behaviour by including the static VAR compensator (SVC), to damp the unnecessary fluctuations and to enhance the dynamic behaviour of the solar photovoltaic power generation, under various levels of PV penetrations. The critical clearing time, rotor swing angle and rotor deviation parameters are determined to know the dynamic characteristics. The improvement of the stability validates the work. A comparison study for the stability with and without the SVC is also presented here.
