Network reliability improvement method based on coordination of network-constructed energy storage and distributed power supply
By identifying the local effective support range of grid-type energy storage and verifying the status after recovery, the problem of support range shrinkage in the existing power supply recovery control of distribution networks is solved, and efficient and reliable power supply recovery is achieved after a distribution network fault.

AI Technical Summary
Existing power supply restoration control methods for distribution networks fail to effectively assess changes in the support status of grid-based energy storage after distributed power sources re-enter or power supply objects are restored, which may lead to power loss again for restored power supply objects, especially affecting the power supply reliability of critical protection objects.
By identifying the local effective support range of grid-type energy storage, the support limitation state after the restoration action is deduced, and the restored power supply objects are covered and verified to select executable restoration actions. This ensures that grid-type energy storage gradually expands the power supply restoration range after fault isolation and avoids the shrinkage of the support range.
It improves the efficiency and reliability of power restoration after a distribution network fault, ensures continuous power supply to critical infrastructure, and avoids further power outages caused by improper restoration actions.
