Dynamic load models in power systems using the measurement approach
TLDR
In this paper, the development of dynamic load models using the measurement approach for the Taipower system is described. But the authors focus on the use of the measured data from an online transient recording system to develop dynamic load model structures.Abstract:
Accurate dynamic load models allow more precise calculations of power system controls and stability limits, which are critical in the planning and operation of power systems. The development of dynamic load models using the measurement approach for the Taipower system are described. Two dynamic load model structures are developed. A procedure for applying a set of measured data from an online transient recording system to develop dynamic load models for the Taipower system is described. A technique based on the concept of confidence interval is used to validate the developed high-order load model structure. Case studies are also presented. >read more

Composite load modeling via measurement approach
H. Renmu,Ma Jin,David J. Hill +2 more
TL;DR: In this paper, a measurement-based composite load model is developed to model load from field measurements, and two cases are studied to illustrate the accuracy of the developed load model on describing the load dynamic characteristics in the actual power system.

Measurement-based dynamic load models: derivation, comparison, and validation
TL;DR: Numerical studies indicate that linear dynamic load models studied in this paper give better results than two nonlinearynamic load models in modeling reactive power behaviors during disturbance while they are comparable in modeling real power behaviors.

A Real Application of Measurement-Based Load Modeling in Large-Scale Power Grids and its Validation
TL;DR: The expectation composite load model is proposed to predict unseen data in power system simulation and control using load characteristic recorders and the probabilistic collocation method is applied to quantitatively analyze uncertainties of the simulation responses raised by the parameters.

Load Representation in Power System Stability Studies
C. Concordia,S. Ihara +1 more
TL;DR: 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.
