Does reactive power control affect a distribution feeder?

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.

What is reactive power?

Reactive Power (measured in Mvar) is used to control voltage levels across the electricity system, keeping them at a safe and efficient level for electricity transportation and consumption. This Reactive Power can be either generated if more is needed, or absorbed if there is too much in the system.

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.

Is there a real micro-grid with a lithium battery energy storage system?

A real Micro-Grid with a Lithium Battery Energy Storage System (BESS) has been deeply described. The Micro-Grid has been implemented and available at ENEA labs (Italian National Agency for New Technologies, Energy and Sustainable Economic Development).

How much reactive power can a Bess provide?

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.

What is reactive power compensation priority control for a special load?

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.
