Systems and methods for facilitating a medium voltage microgrid operation to manage critical loads are disclosed. The system includes at least two fuel cell systems that operate in one of at least two operating modes including a grid-forming mode and a grid-following mode, based on an operation of at least two utility feeders of a grid. The system includes a controller that receives values corresponding to electrical parameter(s) from at least two utility circuit breakers and a load circuit breaker, detects availability status of the utility circuit breakers to supply power to corresponding at least two portions of the critical load, and a connection status of the load circuit breaker, based on the values, and facilitates the at least two fuel cell systems to operate in one of the at least two operating modes. Further, the system is scalable, redundant, and reliable, and reliability and redundancy are customizable.

A method of providing electrical power using a split bus configuration includes receiving a first direct current at a positive bus of a split bus, where the first direct current originates from a first fuel cell segment. A second direct current is received at a negative bus of the split bus, where the second direct current originates from a second fuel cell segment. A third direct current is also received at the split bus such that a combined direct current is formed including the first direct current, the second direct current, and the third direct current. The third direct current originates from an alternative direct current (DC) source. The combined direct current is provided to an inverter such that an alternating current is generated for a load.
