These are load characteristics that allow the user to represent the load as constant current (IPload, IQload) and constant admittance (YPload, YQload). The total load at the bus may be represented as a mixture of constant power, constant current, and constant admittance. When performing time-domain simulations, it is preferred to convert constant power load into constant current and constant admittance characteristics to capture the voltage-dependency of loads.

In dynamic simulations loads are converted from constant load to voltage dependent load. See activity CONL in Program Operation Manual.
