If the power factor decreases below 0.98 lagging, the BESS decreases Ibatt_ref at a rate equal to the reactive power ramp rate, thus increasing the capacitive reactance output of the BESS. Once the system power factor increases past 0.99 lagging, the logic maintains constant Ibatt_Ref and the BESS behaves as a fixed shunt capacitor.
