Battery Energy Storage System (BESS) is capable of providing a contingency FCAS response using one of two methods: OFB), or its frequency control deadband (whichever is narrower); orVia a switching controller, where a step change in active power is triggered when the local frequency exceeds the Frequenc.
While RC rating is a measurement of time, an amp hour rating is the measurement of how many amps the battery can provide in one hour. Reserve capacity is measured in minutes, whereas amp hours are measured in amps per hour. To convert reserve capacity to amp hours (AH), one must divide the reserve capacity by 60 and multiply the result by 25.
