Preemptive charging for power outage mitigation
Preemptively charging rechargeable energy storage systems (RESSs) in advance of an electrical grid outage. The preemptive charging may include generating a weather map of a geographical area anticipated to be impacted with a storm or a natural event of a severity predicted to induce a power outage, which may include generating a distribution map of an electrical power distribution network within the geographical area, generating an outage map by overlaying the weather map relative to the distribution map to identify one or more intersections where the power outage is predicted, and scheduling or otherwise implementing preemptively charging of one or more the RESSs downstream of the intersections in advance of the power outage.
