Abstract

A method includes a resource selection for a control sub-slot of a balance event. The method includes computing availability schedules and creating a priority list of resources. The priority list includes an order in which the resources are added to a sub-group activated in the control sub-slot. The method includes calculating a resource capacity of the sub-group. The method includes receiving an energy target. If the resource capacity is less than the energy target, the method may include adding one of the resources that has a first position on the priority list to the sub-group and calculating an updated resource capacity. The method includes determining whether the updated sub-group resource capacity is greater than or equal to the energy target. If the updated sub-group resource capacity is greater than or equal to the energy target, the method may include communicating a command signal to the resources.

Claims

1. A method of resource selection for a control sub-slot of a micro-balance event, the method comprising:

computing availability schedules for one or more resources;

sorting the resources by a resource control status that denotes a control status of the resources in the control sub-slot, wherein the control sub-slot represents a period of time during which one or more resources are controlled in a particular operational state and the resource control status includes;

a first resource control status that denotes a resource with cycling behavior that has not been turned off a maximum percentage of time allowed, and is to be turned off in the control sub-slot to increase energy balance capacity;

a second resource control status that denotes that it is desirable to turn off in the control sub-slot to increase program benefits for a utility;

a third resource control status that denotes that it is desirable for the resource to be controlled again within a next one or more hours; and

a fourth resource control status that denotes that it is desirable that the resource is controlled again within a same day;

creating a priority list of the sorted resources based on one or more prioritization rules and the availability schedules, the priority list including an order in which the resources are added to a controlled sub-group of the resources that are controlled during the control sub-slot;

calculating a sub-group resource capacity that includes a sum of resource capacities of a subset of the resources included in the controlled sub-group;

receiving an energy target that includes an energy amount to be balanced during the micro-balance event;

determining whether the sub-group resource capacity is greater than or equal to the energy target;

in response to a determination that the sub-group resource capacity is less than the energy target, adding one of the resources that has a first position on the priority list to the controlled sub-group and calculating an updated sub-group resource capacity that includes the sub-group resource capacity and a resource capacity of the added resource;

determining whether the updated sub-group resource capacity is greater than or equal to the energy target; and

in response to a determination that the updated sub-group resource capacity is greater than or equal to the energy target, transitioning an operational state of the resources in the controlled sub-group to implement the micro-balance event by communicating a command signal to the resources that controls an operational state of the resources to affect energy use or energy production of the resources.

among resources with comparable event participations, further sorting the resources based on the resource capacity such that the resources having larger resource capacities are prior to the resources having smaller resource capacities,

wherein;

the sorting of the resources is such that the resources with the first resource control status are prior to the resources with the second resource control status, the resources with the second resource control status are prior to the resources with the third resource control status, and the resources with the third resource control status are prior to the resources with the fourth resource control status.

further updating the energy target based on a remaining number of control sub-slots;

determining whether the sub-group resource capacity is smaller than the updated energy target;

in response to the sub-group resource capacity being smaller than the updated energy target, adding one of the resources that has the first position on the priority list to the controlled sub-group;

in response to the sub-group resource capacity not being smaller than the updated energy target, determining whether the sub-group resource capacity is equal to the updated energy target; and

in response to the sub-group resource capacity not being equal to the updated energy target, removing a most recently added resource from the controlled sub-group.

the resources include one or more or a combination of an air conditioner, a photovoltaic panel, and an electric vehicle that are included in a virtual power plant (VPP); and

the micro-balance event includes a portion of a substantially continuous balance event.

8. The method of claim 1, wherein:

the resources each include a resource type; and

the resources of a first resource type are ordered above the resources of a second resource type.

9. The method of claim 1, wherein the prioritization rules are based on one or more of a combination of:

resource types,

customer constraints, and

program constraints.

10. The method of claim 1, further comprising for a next control sub-slot:

creating a subsequent priority list of the resources;

calculating a subsequent sub-group resource capacity that includes a sum of resource capacities of a subset of the resources included in the controlled sub-group;

determining whether the subsequent sub-group resource capacity is greater than or equal to the energy target; and
