- cim:LoadMotor Aggregate induction motor load. This model is used to represent a fraction of an ordinary load as "induction motor load". It allows a load that is treated as an ordinary constant power in power flow analysis to be represented by an induction motor in dynamic simulation. This model is intended for representation of aggregations of many motors dispersed through a load represented at a high voltage bus but where there is no information on the characteristics of individual motors. Either a "one-cage" or "two-cage" model of the induction machine can be modelled. Magnetic saturation is not modelled. This model treats a fraction of the constant power part of a load as a motor. During initialisation, the initial power drawn by the motor is set equal to <i>Pfrac</i> times the constant <i>P</i> part of the static load. The remainder of the load is left as a static load. The reactive power demand of the motor is calculated during initialisation as a function of voltage at the load bus. This reactive power demand can be less than or greater than the constant <i>Q</i> component of the load. If the motor's reactive demand is greater than the constant <i>Q</i> component of the load, the model inserts a shunt capacitor at the terminal of the motor to bring its reactive demand down to equal the constant <i>Q</i> reactive load. If an induction motor load model and a static load model are both present for a load, the motor <i>Pfrac</i> is assumed to be subtracted from the power flow constant <i>P</i> load before the static load model is applied. The remainder of the load, if any, is then represented by the static load model.

- cim:LoadAggregate Aggregate loads are used to represent all or part of the real and reactive load from one or more loads in the static (power flow) data. This load is usually the aggregation of many individual load devices and the load model is an approximate representation of the aggregate response of the load devices to system disturbances. Standard aggregate load model comprised of static and/or dynamic components. A static load model represents the sensitivity of the real and reactive power consumed by the load to the amplitude and frequency of the bus voltage. A dynamic load model can be used to represent the aggregate response of the motor components of the load.
