Power Quality and Stability
Observations V2H Systems
V2H systems play pivotal role in
enhancing residential energy flexibility by
enabling bidirectional power exchange,
supporting backup power functionality
during grid outages, and facilitating
intelligent energy management strategies
that improve overall system resilience and
operational efficiency.
