Method And System For Providing Flexible Reserve Power For Power Grid
An optimization-based method and system is disclosed to enable heterogeneous loads and distributed energy resources (DERs) to participate in grid ancillary services, such as spinning and non-spinning reserves, and ramping reserves. The method includes receiving inputs for decision parameters for optimizing an objective for obtaining flexible reserve power, solving the objective for obtaining flexible reserve power, determining a reserve power schedule for a prediction horizon for providing flexible reserve power based on the objective, generating a service bid based on the reserve power schedule for the power grid; and when the service bid is accepted, providing flexible reserve power to the power grid based on the service bid.

- 1. A method for providing flexible reserve power to a power grid, the method comprising:
receiving a plurality of inputs for a plurality of decision parameters for optimizing an objective for obtaining flexible reserve power; solving the objective for obtaining flexible reserve power by processing the plurality of inputs, wherein inputs associated with a plurality of loads and distributed energy resources from the plurality of inputs are aggregated as inputs from a distributed flexible resource; determining a reserve power schedule for a prediction horizon for providing flexible reserve power to the power grid based on the objective while maintaining power requirements of the distributed flexible resource; generating a service bid based on the reserve power schedule for the power grid; and when the service bid is accepted, providing flexible reserve power to the power grid based on the service bid.
- 8. A system for providing flexible reserve power for a power grid, the system comprising:
a distributed flexible resource comprising a plurality of loads and at least one distributed energy resource; a power management unit configured for controlling the distributed flexible resource; a dual optimizer unit configured for determining a reserve power schedule for a prediction horizon for providing flexible reserve power to the power grid based on an objective for providing flexible reserve power while maintaining power requirements of the distributed flexible resource; and a reserve power unit for providing flexible reserve power to the power grid based on the reserve power schedule.
