Microgrid electrical load management
A system for completing a well, including a generator, and a plurality of electric load components, each electric load component powered by the generator. The system further includes a load shedding control panel that monitors the generator and, if the generator loses functionality, is capable of deactivating one or more of the plurality of electric load components to reduce the electric load.
1. A system comprising:
a generator;
hydraulic fracturing equipment, including a blender, electrically connected to the generator;
an electric drilling rig, the electric drilling rig electrically connected to the generator;
a load shedding control panel that monitors the generator and, if the generator loses functionality, is capable of deactivating the hydraulic fracturing equipment before the electric drilling rig to reduce the electric load while ensuring continued power to the drilling rig, and wherein the load shedding panel is programmed to deactivate the blender after other hydraulic fracturing equipment is deactivated;
a first switch gear positioned between the generator and the hydraulic fracturing equipment to distribute power between the generator and the hydraulic fracturing equipment, and a second switchgear positioned to distribute power between the generator and the electric drilling rig.
2. The system of claim 1 , wherein the generator is a natural gas turbine generator, a natural gas generator, or a diesel generator.
3. The system of claim 1 , wherein the hydraulic fracturing equipment is selected from the group consisting of electric hydraulic fracturing pumps, a blender, sand equipment, a hydration unit, and a data van.
4. The system of claim 3 , wherein the load shedding panel prioritizes the order in which particular hydraulic fracturing equipment and the electric drilling rig will be deactivated.
5. The system of claim 1 , wherein the generator is in selective electrical communication with a power grid.
6. A method of managing power between an electric drilling rig and hydraulic fracturing equipment, including a blender, the method comprising the steps of:
a) powering the hydraulic fracturing equipment with a generator;
b) distributing power between the electric drilling rig and the generator with at least one switchgear;
c) distributing power between the generator and the hydraulic fracturing equipment with the at least one switchgear;
d) monitoring the generator to determine when the generator loses functionality;
e) when the generator loses functionality, selectively deactivating the hydraulic fracturing equipment before the electric drilling rig to decrease the load; and
f) prioritizing the deactivation of the hydraulic fracturing equipment so that the blender is deactivated after other hydraulic fracturing equipment is deactivated.
7. The method of claim 6 , further comprising:
distributing power from the generator to a power grid.
8. The method of claim 6 , wherein step c) is carried out by a load shedding control panel that monitors the generator to determine when the generator loses functionality.
