Capacity value of energy storage in distribution networks
In general, ES capacity value is determined by the plant''s ability to support demand under outage conditions – in this case, single and double network faults. It follows that a key factor in determining ES contribution is the duration of outages; the longer the outage duration, the more energy is required from ES.
