Microgrid autosynchronizing using remote recloser inputs and outputs

A non-transitory, computer readable medium comprising instructions that, when executed by one or more processors, cause operations comprising:

• sending, from a recloser control, a trip signal to a recloser at a point of common coupling (PCC) to trip the recloser to an open position, thereby islanding a microgrid from an area electric power system (EPS);
• acquiring, via the recloser control, a first set of measurements indicating electrical characteristics of the area EPS;
• acquiring, via the recloser control, a second set of measurements indicating electrical characteristics of the microgrid;
• and
• sending, via the recloser control, a synchronization signal to a microgrid controller of the microgrid indicating a difference between the first set of measurements and the second set of measurements to allow the microgrid controller to adjust the electrical characteristics of the microgrid to synchronize the microgrid to the area EPS based on the first set of measurements and the second set of measurements;
• receiving, via the microgrid controller, the synchronization signal from the recloser control indicating the difference between the first set of measurements and the second set of measurements;
• determining, via the microgrid controller, an optimal control of a plurality of distributed energy resources (DERs) to synchronize the microgrid with the area EPS according to the difference;
• sending, via the microgrid controller, a control signal to at least one of the plurality of DERs to adjust a setting of the at least one of the plurality of DERs to cause the at least one of the plurality of DERs to adjust the electrical characteristics of the microgrid to synchronize the microgrid with the area EPS;
• following sending the synchronization signal, confirming, via the recloser control, that the microgrid has been synchronized to the area EPS by determining that the first set of measurements and the second set of measurements are within a window of each other;
• and
• upon confirming that the microgrid has been synchronized to the area EPS, sending, via the recloser control, a close command to the recloser to close the recloser.

A method of commissioning a recloser control in an electric power delivery system, comprising:

• communicatively coupling the recloser control with a recloser at a point of common coupling between a microgrid of the electric power delivery system and an area electric power system (EPS) of the electric power delivery system;
• coupling a first sensor between the recloser and the area EPS to allow the recloser control to receive a first set of measurements indicating electrical characteristics of the area EPS;
• coupling a second sensor between the recloser and the microgrid to allow the recloser control to receive a second set of measurements indicating electrical characteristics of the microgrid;
• setting the recloser control to send a synchronization signal to a microgrid controller indicating a difference between the first set of measurements and the second set of measurements to allow the microgrid controller to synchronize the microgrid to the area EPS and to, upon confirming that the microgrid has been synchronized to the area EPS by the microgrid controller, sending a close command to close the recloser, thereby reconnecting the microgrid to the area EPS;
• and
• setting the microgrid controller to receive the synchronization signal from the recloser control indicating the difference between the first set of measurements and the second set of measurements, to determine control of a plurality of distributed energy resources (DERs) to synchronize the microgrid with the area EPS according to the difference, and to send a control signal to at least one of the plurality of DERs to adjust a setting of the at least one of the plurality of DERs to cause the at least one of the plurality of DERs to synchronize the electrical characteristics of the microgrid with the electrical characteristics of the area EPS.
