Abstract

The present disclosure provides systems and methods for controlling an electrical system. The electrical system includes a plurality of backup power sources, such as an electric vehicle battery, a photovoltaic system, and an energy storage system. The electrical system includes a service panel electrically coupled to a plurality of electrical loads. The electrical system includes an energy control system electrically coupled to the plurality of backup power sources, the service panel, and a utility grid. The energy control system converts to a plurality of settings based on the number of available backup power sources. The energy control system determines the availability of the backup power sources according to a predetermined protocol such that one or more backup power sources are prioritized over other backup power sources.

Claims (32)

1. An electrical system, comprising:

a plurality of backup power sources including a first backup power source, a second backup power source, and a third backup power source;

a service panel electrically coupled to a plurality of electrical loads and a remotely-controlled breaker, wherein the remotely-controlled breaker is coupled to one or more of the plurality of electrical loads; and

an energy control system having a grid interconnection electrically coupled to a utility grid, a load interconnection electrically coupled to the service panel, and a backup interconnection configured to be electrically coupled to the plurality of backup power sources, wherein the energy control system is configured to:

adjust power inputted from one or more of the plurality of backup power sources when a detected current rating of the energy control system exceeds a maximum ampacity rating;

in response to disrupting the power inputted, operate in one of a plurality of settings, the settings comprising:

a first setting, wherein the energy control system is electrically coupled to the first and second backup power sources and configured to receive power from the first backup power source,

a second setting, wherein the energy control system is electrically coupled to the first and second backup power sources and configured to receive power from the first and second backup power sources, and

a third setting, wherein the energy control system is electrically coupled to the first, second, and third backup power sources and configured to receive power from the first, second, and third backup power sources; and

send instructions to the remotely-controlled breaker to connect the one or more of the plurality of electrical loads to the load interconnection.

2. The electrical system of claim 1 , wherein the first backup power source is a backup photovoltaic (PV) power generation system configured to generate power.

3. The electrical system of claim 2 , wherein the second backup power source is an electric vehicle (EV) charger port configured to charge power to and discharge power from an EV battery.

4. The electrical system of claim 3 , wherein operating in the second setting, the energy control system is configured to receive power from the second backup power source before receiving power from the first backup power source.

5. The electrical system of claim 3 , wherein the third backup power source is an energy storage system configured store the power generated by the backup PV power generation system.

6. The electrical system of claim 5 , wherein operating in the third setting, the energy control system is configured to receive power from the second backup power source before receiving power from the first and third backup power sources.

7. The electrical system of claim 1 , wherein operating in the second setting, the energy control system is configured to receive power from the first and second backup sources according to a predetermined protocol.

8. The electrical system of claim 7 , wherein the second backup power source is prioritized over the first backup power source according to the predetermined protocol.

9. The electrical system of claim 1 , wherein operating in the third setting, the energy control system is configured to receive power from the first, second, and third backup power sources according to a predetermined protocol.

10. The electrical system of claim 9 , wherein the second backup power source is prioritized over the first and third backup power sources according to the predetermined protocol.

11. The electrical system of claim 1 , wherein the energy control system is configured to switch between:

an on-grid mode electrically connecting the grid interconnection to the load interconnection and the backup interconnection; and

a backup mode electrically disconnecting the grid interconnection from the load interconnection and the backup interconnection.

12. An electrical system, comprising:

a plurality of backup power sources including a first backup power source, a second backup power source, and a third backup power source;

a service panel electrically coupled to a plurality of electrical loads and a remotely-controlled breaker, wherein the remotely-controlled breaker is coupled to one or more of the plurality of electrical loads; and

an energy control system having a grid interconnection electrically coupled to a utility grid, a load interconnection electrically coupled to the service panel, and a backup interconnection configured to be electrically coupled to the plurality of backup power sources,

wherein the energy control system includes a controller configured to:

determine whether the first backup power source is available for supplying power to the service panel;

determine whether the second backup power source is available for supplying power to the service panel after determining the availability of the first backup power source;

determine whether the third backup power source is available for supplying power to the service panel after determining the availability of the second backup power source;

adjust power inputted from one or more of the first backup power source, the second backup power sources, and the third backup power source when a detected current rating exceeds a maximum ampacity rating; and

send instructions to a remotely-controlled breaker to provide power to one or more of a plurality of electrical loads.
