Specifies the commodity and quantity a value is describing.
This enumeration is used to specify the commodity and quantity of an accompanying value. It's used in many places where S2 information is shared in a commodity-agnostic way; for example, in PEBC.EnergyConstraint it's used to specify what commodity/quantity the constraint is about.
ELECTRIC.POWER.3_PHASE_SYMMETRIC
Electric power, described in Watt when power is equally shared among the three phases. Only applicable for 3 phase devices. A value refers to the total power on the three phases.
ELECTRIC.POWER.L1
Electric power, described in Watt on phase 1. If a device utilizes only one phase, it should always use L1.
ELECTRIC.POWER.L2
Electric power, described in Watt on phase 2. Only applicable for 3 phase devices.
ELECTRIC.POWER.L3
Electric power, described in Watt on phase 3. Only applicable for 3 phase devices.
HEAT.FLOW_RATE
Flow rate of heat carrying gas or liquid, described in liters per second.
HEAT.TEMPERATURE
Heat, described in degrees Celsius.
HEAT.THERMAL_POWER
Thermal power, described in Watt.
HYDROGEN.FLOW_RATE
Hydrogen gas flow rate, described in grams per second
NATURAL_GAS.FLOW_RATE
Natural gas flow rate, described in liters per second.
OIL.FLOW_RATE
Oil flow rate, described in liters per hour.
