Capacitor

For high-energy storage with capacitors in series, some safety considerations must be applied to ensure one capacitor failing and leaking current does not apply too much voltage to the other series capacitors. Usually, the values of these capacitors are not given in farads but rather as a reactive power in volt-amperes reactive (var).

Emerging grid-forming power converters for renewable energy and storage

In general, the choice of an ESS is based on the required power capability and time horizon (discharge duration). As a result, the type of service required in terms of energy density (very short, short, medium, and long-term storage capacity) and power density (small, medium, and large-scale) determine the energy storage needs [53]. In addition

What is reactive power and why does it matter?

This is because energy is stored in capacitors and inductors whereas it is consumed in resistors. Capacitors store energy in their electric fields because they charge and discharge in an attempt to keep voltage constant: the energy is stored when the capacitor is charging and returned to the source when it discharges.
