Abstract
A method and a system for operating a heating, ventilation, and air conditioning (HVAC) centric energy hub. A power conversion system is configured to condition power and is coupled to an HVAC system, a power grid, an energy storage device, an alternative energy source, and one or more loads. An energy management system is coupled to the power conversion system, the energy management system is configured to manage distribution of power from the power grid, the energy storage device, and the alternative energy source to the one or more loads and is further configured to communicate with energy management systems of other hubs.
Claims16
A heating, ventilation, and air conditioning (HVAC) centric energy hub at a residential building or a commercial building, the hub comprising:
- a power conversion system that is configured to condition power for and is coupled to an HVAC system, a power grid, an energy storage device, an alternative energy source, and one or more loads;
- and
- an energy management system coupled to the power conversion system, the energy management system is configured to manage distribution of power from the power grid, the energy storage device, and the alternative energy source to the one or more loads and is further configured to communicate with at least one other hub at a residential building or a commercial building, the at least one other hub including a power conversion system and an energy management system;
- wherein the energy management system is further configured to control the power conversion system to provide energy-as-a-service to one or more loads based at least in part on the communication with the energy management system of the at least one other hub, wherein the at least one other hub is located remotely from the hub;
- wherein the power conversion system is further configured to provide power to the power grid to supply power to one or more external loads directly connected to the at least one other hub based at least in part on the communication with the energy management system of the at least one other hub;
- wherein the at least one other hub includes:
- a further power conversion system that is configured to condition power for and is coupled to a further HVAC system, the power grid, a further energy storage device, a further alternative energy source, and one or more further loads;
- and
- a further energy management system coupled to the further power conversion system.

A method for operating a heating, ventilation, and air conditioning (HVAC) centric energy hub at a residential building or a commercial building, the method comprising:
- managing, by an energy management system of the hub, distribution of power from a power grid, an energy storage device, and an alternative energy source to the one or more loads through a power conversion system;
- communicating with at least one other hub at a residential building or a commercial building, the at least one other hub including a power conversion system and an energy management system, to manage the distribution of power, and
- wherein the power conversion system is configured to condition power for and is directly connected to an HVAC system, the power grid, the energy storage device, the alternative energy source, and the one or more loads;
- the method further comprising controlling the power conversion system to provide energy-as-a-service to one or more loads based at least in part on the communication with the energy management system of the at least one other hub, wherein the at least one other hub is located remotely from the hub;
- the method further comprising providing power, using the power conversion system, to the power grid to supply power to one or more external loads directly connected to the other hubs based at least in part on the communication with the energy management system of the at least one other hub;
- wherein the at least one other hub includes:
- a further power conversion system that is configured to condition power for and is coupled to a further HVAC system, the power grid, a further energy storage device, a further alternative energy source, and one or more further loads;
- and
- a further energy management system coupled to the further power conversion system.
