Energy storage to achieve reactive power compensation

Why do wind farms need energy storage and reactive power compensation?

Because the loads and the wind farms' output fluctuate during the day, the use of energy storage and reactive power compensation is ideal for the power system network. Energy storage and reactive power compensation can minimize real/reactive power imbalances that can affect the surrounding power system.

What is reactive power compensation?

It was initially decided that the size of reactive power placed at each wind turbine should be equal to the reactive power required during no load (no wind). The most common reactive power compensation is a fixed capacitor. The inclusion of reactive power compensation using SVC installed at Bus 40 was an improvement to the previous systems.

What is the difference between reactive power and energy storage?

Thus there is no reactive power interchange with the energy storage. The reactive power must be passed through the line. Although the total current still carries the reactive power component through the line, it is smaller compared to the one without energy storage (ITOT_NEW < ITOT_OLD).

Does dynamic reactive power compensation reduce operative cost?

The inclusion of the dynamic reactive power compensation with batteries reduces the total operative daily cost for both test feeders in 25.6223% and 14.9347% for the 33- and 69-node test systems, respectively; which implies 2.2534% and 2.7242% of additional improvement when reactive power capabilities of the VSCs are used. 5.2.2.

Do dynamic active and reactive power compensation improve electrical performance?

In general terms, we can affirm that for both test systems, the dynamic active and reactive power compensation from batteries improve the electrical performance of the ac network when higher variability of renewable generation and power consumption are considered under an economic dispatch environment.

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.
