6 FAQs about [Reactive power in solar plant]

How to improve reactive power capability of solar and wind plants?

If needed to meet interconnection requirements, the reactive power capability of solar and wind plants can be further enhanced by adding of a static var compensator (SVC), static compensators (STATCOMS), and other reactive support equipment at the plant level.

What happens if a solar PV plant is not accounted for properly?

If the reactive power requirement of the three winding transformers of a solar PV plant are not accounted for carefully, additional quantity of reactive power compensation devices may be required to meet the reactive power requirement of the plant, leading to additional cost being incurred.

What is a reactive power factor?

Do solar PV inverters need Dynamic Reactive support?

Sometimes, external dynamic reactive support is required to assist with voltage ride-through compliance. During periods of low wind or solar resource, some generators in the plant may be disconnected from the grid. The DC voltage for solar PV inverters may limit the reactive power capability of the inverters.

What are reactive power limitations based on grid voltage?

Reactive power limitations based on grid voltage. Can be countered with on load tap changer or deenergized tap optimization. Inverter Maximum Power Point Tracking typically selects a DC voltage that optimizes real power output. Injection of capacitive lagging reactive power onto grid can be problematic, especially with lower DC rated inverters.
