What happens if absorbed reactive power is greater than a threshold?

If the absorbed reactive power is greater than a settled threshold in the measurement point, the BESS provides the reactive power given by the difference between the reactive power provided by the grid and the threshold. The result is limited to maximum reactive power of inverter׳s BESS.

What is reactive power?

Reactive power provides no useable power, but increases the load on the power system and reduces the amount of real, useful power that can be delivered. These concepts are explored with the aid of the power triangle, P-Q unit circle, and real waveforms. to find the answer to your question , you can consult this link

How do you calculate reactive power?

If the inverter׳s BESS does not provide all the available apparent power, the control system calculates the available reactive power (Q a v (t)); it can provide or absorb based on the measures through the equation: (1) Q a v (t) = 30 2 P B E S S 2 (t) where the 30 kVA power value is the maximum apparent power of the BESS in Eq. (1).
