Why power factor is lower at power grid with solar?
The active power and reactive power consumed by the system is fixed. When there is photovoltaic, photovoltaic provides active power, so the active power provided by the system decreases, and the reactive power remains unchanged, so the power factor decreases. If the active power provided by photovoltaics is close to the active power consumed by the load, the active power provided by the system will be very small. At this time, high reactive power compensation accuracy is required, and the remaining reactive power must be small to improve the power factor.
How to improve power factor at power grid with solar?
Traditional capacitor banks compensation cannot meet the accurate requirements, but Static Var Generator SVG compensation is required.
