DR Resource and DR Asset Definitions

Below is a summary of some existing definitions.

UCA: A DR Resource is used during the enrollment process. A DR Resource as a logical entity is a group of Assets that represents a dispatchable entity.

Other work from Houston: A Resource may be an individual asset or a group of assets that represent a dispatchable entity.

[This following is from an earlier draft of the other work from Houston. The terms Response Method and Response Method Aggregation were deprecated.

Response Method: A measurable action taken in response to an instruction to change consumption.

Response Method Aggregation: A logical entity that has a reportable interval level consumption, e.g. a site may also be a physical entity that may have its own meter, a neighborhood of homes that has a net meter, or an estimate of consumption of an aggregation of retail customers.

Resource: A market-dependent group of Response Method Aggregations that represents a dispatchable entity.]

UCA: DR Asset is defined as an end device that is capable of shedding load in response to Demand Response Events, Electricity Price Signals or other system events (e.g. under frequency detection).

[This definition should include some reference to the fact that it is defined as something separate from a Resource for purposes of Direct Load Control. The interactions defined for UCA also specify that an Asset can consume a Price Signal.]

CIM: EndDeviceAsset: AssetContainer that performs one or more end device functions. One type of EndDeviceAsset is a MeterAsset which can perform metering, load management, connect/disconnect, accounting functions, etc. Some EndDeviceAssets, such as ones monitoring and controlling air conditioner, refrigerator, pool pumps may be connected to a MeterAsset. All EndDeviceAssets may have communication capability defined by the associated ComFunction(s). An EndDeviceAsset may be owned by a consumer, a service provider, utility or otherwise.

There may be a related end device function that identifies a sensor or control point within a metering application or communications systems (e.g., water, gas, electricity).

Some devices may use an optical port that conforms to the ANSI C12.18 standard for communications.

CIM: EndDeviceControl (Logical End Device): Instructs an EndDeviceAsset (or EndDeviceGroup) to perform a specified action.
