About Consider the active and reactive power of the energy storage system
The monitoring and control system reads the active and the reactive power in the measurement point. 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.
