Although acknowledging that non-generating resources (e.g., storage) can provide reactive power service, SPP''s tariff only allows "Qualified Generators" to receive compensation. The rate of compensation for reactive power in SPP is $2.26 per qualifying MVAr per hour. This discrepancy is arguably unduly discriminatory and should
The quality of energy systems. Reactive energy compensation is an essential process in improving energy efficiency. It reduces the power consumption and thus its cost, enables optimum use of installations by preventing them being oversized, and more generally it improves the quality of energy systems. Contents: 1.

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 number of solutions, an approach to support the choice of the solution is also proposed.
This approach further improves the converter''s performance by reducing the fluctuation in the capacitor voltages and eventually the losses. Finally, the operating range of the MMC-based ES-STATCOM system is being discussed, which lays down the operating limit for active power compensation with reactive power compensation given the priority.

A. Reactive Power and Regulation. 4. Almost all bulk electric power is generated, transported, and consumed in alternating current (AC) networks. Elements of AC systems supply and consume two kinds of power: Real power and reactive power. Real power accomplishes useful work ( e.g., runs motors and lights lamps).
In power systems, reactive power services are a type of electric-power ancillary service to stabilize the system voltage within a safe range, which is provided by reactive power resources such as conventional generation units and reactive power compensation devices on a paid or free basis [14], [15], [16], [17].
