TLDR
In this paper, the authors present a load model for power system stability studies, which is qualitatively different from generator load modeling in many aspects, such as reliability of load estimates, models of different components must be combined to obtain a reasonably manageable overall system model and field measurements are not at all easy.Abstract:
Proper representation of load is important in power system stability studies, but it is a difficult task. Load modeling is qualitatively different from generator modeling in many aspects. Composition of load needs to be reliably estimated, models of different components must be combined to obtain a reasonably manageable overall system model, and field measurements are not at all easy.read more

Physically Based Modeling of Cold Load Pickup
S. Ihara,Fred C. Schweppe +1 more
TL;DR: In this paper, a general, physically based, probabilistic model of power system load has been developed for short-term prediction of system demand by composition, and accounts for lifestyle dependency and weather dependency as well as effects of other exogenous processes.
