As seen before, the BESS can compensate the active and reactive power on the EV fast charge. A high active power threshold has been chosen in this experimentation to avoid active power compensation. So the energy consumption to cover the reactive power compensation service has been analyzed.
Reactive power compensation priority control for a special load In this experimentation the priority to the reactive power has been given. As seen before, the BESS can compensate the active and reactive power on the EV fast charge. A high active power threshold has been chosen in this experimentation to avoid active power compensation.
One way to mitigate such effects is using battery energy storage systems (BESSs), whose technology is experiencing rapid development. In this context, this work studies the influence that the reactive power control dispatched from BESS can have on a real distribution feeder considering its original configuration as well as a load transfer scenario.
The reactive power control is part of CEI 0-16 and CEI 0-21, Italian standards defining the rules of connection of active and passive users to the grid ( Delfanti et al., 2015 ).
The maximum active power provided by the BESS is 20 kW. So, a quantity of reactive power is available to be used. Indeed the control system can use that reactive power and the result is shown in Fig. 17. Fig. 17 shows as the reactive power requested by the EV fast charge can be provided by the BESS. In this way the power factor is close to 1.
The active power control performs a peak shaving logic that has been already tested and explained by the authors in Sbordone et al. (2015). The monitoring and control system read the active and the reactive power in the measurement point.
