Microgrid system structured to detect overload conditions and take corrective actions relating thereto

摘要

A distribution manager includes a main bus, a first connection coupled to the main bus through a first circuit breaker and being structured to couple the distribution manager to an inter-microgrid connection system, a second connection coupled to the main bus through a second circuit breaker and being structured to couple the distribution manager to the inter-microgrid connection system, and a third circuit breaker coupled to the main bus and being structured to be coupled to a load. The distribution manager is configured to detect an overload condition and in response thereto (i) request to bring an offline distributed source online, (ii) if an offline distributed source cannot be brought online, request to shed the load, and (iii) if the load cannot be shed, cause the second circuit breaker to downwardly adjust the trip curve thereof.

1. A distribution manager, comprising:
a main bus; a first connection coupled to the main bus through a first circuit breaker, the first connection being structured to couple the distribution manager to an inter-microgrid connection system at a first location; a second connection coupled to the main bus through a second circuit breaker, the second connection being structured to couple the distribution manager to the inter-microgrid connection system at a second location, the second circuit breaker having a selectively adjustable trip curve; and a third circuit breaker coupled to the main bus, the third circuit breaker being structured to be coupled to a load; wherein the distribution manager is structured and configured to detect an overload condition on the inter-microgrid connection system and in response thereto (i) request to bring an offline distributed source coupled to the main bus online, (ii) if an offline distributed source coupled to the main bus cannot be brought online, request to shed the load, and (iii) if the load cannot be shed, cause the second circuit breaker to downwardly adjust the selectively adjustable trip curve thereof.
