The various commodity quantities introduced by the S2 standard.

Power measurement represents the measurement of electrical power at a given moment

• power value ^dp
• timestamp ^dp
• has technical context ^dp
• is about commodity quantity ^op
• is measured in ^op
• has power property ^op
• is measured by ^op

• consists of power measurement ^op
• measures power ^op

Power property refers to the various forms of electrical power that can be quantified in a system. It can describe any of these forms of power (active, reactive, or apparent).

Power Device refers to an electrical device used to measure, monitor, or control different forms of power in a system. Such as power meters or energy meters.

• is measured by ^op
• is targeted on ^op

Active power is the actual power consumed by devices to perform work, measured in watts (W)

The total power supplied to the system, combining both active and reactive power, measured in volt-amperes (VA).

The power that oscillates between the source and load without doing useful work, measured in volt-amperes reactive (VAR).

An entity responsible for managing flexibility in energy consumption and generation, optimizing resource usage based on grid conditions and demand response strategies.

An event triggered to adjust energy consumption or production in response to grid conditions, market signals, or demand-side management policies.

• DR signal identifier ^dp
• signal type ^dp
• priority ^dp
• has status ^dp
• start time ^dp
• end time ^dp
• has flex manager ^op
• is targeted on ^op

A system or entity responsible for overseeing and optimizing the allocation, utilization, and scheduling of energy resources within a smart grid or charging infrastructure.

A generic entity representing an asset within the energy system, such as energy storage, generation units, or flexible loads, that can be managed or optimized.

• consists of power measurement ^op
• has resource manager ^op

• sri4building:Building ^c
• sri4building:HeatPump ^c
• sri4pv:Photovoltaic ^c

This describes the connection between the power data and the type of commodity quantity it represents.

• This describes the connection between the power data and the type of commodity quantity it represents.

• Indicates the measurement unit associated with a quantity.

Relates a resource to its associated power measurement, representing the energy usage or generation of the resource.

Indicates that a resource is managed by a specific resource manager responsible for its optimization and control.

Associates a power measurement with its specific power-related properties, such as voltage, current, or frequency.

Specifies the power device responsible for measuring a given power measurement within the energy system.

Denotes that a power device is responsible for measuring power values within the system.

Links a demand response event to a flexibility manager responsible for handling energy adjustments and optimizations.

Defines the power device that is the target of a specific demand response event.

This property indicates whether the power value pertains to production (e.g., PV production) or consumption.
