EnergyConsumer

Class Description

Generic user of energy - a point of consumption on the power system model.
EnergyConsumer.pfixed, .qfixed, .pfixedPct and .qfixedPct have meaning only if there is no LoadResponseCharacteristic associated with EnergyConsumer or if LoadResponseCharacteristic.exponentModel is set to False.

Attributes

Name Type Description
customerCount Integer Number of individual customers represented by this demand.
grounded Boolean Used for Yn and Zn connections. True if the neutral is solidly grounded.
p ActivePower Active power of the load. Load sign convention is used, i.e. positive sign means flow out from a node.
For voltage dependent loads the value is at rated voltage.
Starting value for a steady state solution.
pfixed ActivePower Active power of the load that is a fixed quantity and does not vary as load group value varies. Load sign convention is used, i.e. positive sign means flow out from a node.
pfixedPct PerCent Fixed active power as a percentage of load group fixed active power. Used to represent the time-varying components. Load sign convention is used, i.e. positive sign means flow out from a node.
phaseConnection PhaseShuntConnectionKind The type of phase connection, such as wye or delta.
q ReactivePower Reactive power of the load. Load sign convention is used, i.e. positive sign means flow out from a node.
For voltage dependent loads the value is at rated voltage.
Starting value for a steady state solution.
qfixed ReactivePower Reactive power of the load that is a fixed quantity and does not vary as load group value varies. Load sign convention is used, i.e. positive sign means flow out from a node.
qfixedPct PerCent Fixed reactive power as a percentage of load group fixed reactive power. Used to represent the time-varying components. Load sign convention is used, i.e. positive sign means flow out from a node.
