The reactive power compensation considers the maximum active power of the converter, to minimize the cost of the system. In consequence, when the energy storage system is at its maximum discharge mode, the reactive power compensation function will be inhibited. Since the multi-objective optimization generates a Pareto-optimal set with a large ...
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).
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.
It was determined that the original installations of reactive power compensations were not sufficient to help regulate the voltage in the area. 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).
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.

Reactive power compensation helps balance load and generation, especially during peak demand times when the stability of the grid is most vulnerable. Regulations and standards often require utilities to maintain specific voltage levels, making reactive power compensation a key component of grid compliance.
