TLDR
In this paper, the authors proposed a load model where real and apparent power are exponentially dependent on voltage to avoid unreliability of the reactive power voltage exponent, and the error that could be made by assuming constant power factor of the load during voltage variation is estimated.About:

OPF-Based CVR Operation in PV-Rich MV–LV Distribution Networks
TL;DR: A centralized, three-phase AC optimal power flow (OPF)-based CVR scheme that, using monitoring, on-load tap changers and capacitors across MV and LV, actively manages voltages to minimize energy consumption, even with high PV penetration, while considering MV–LV constraints is proposed.

Modelling and identification of nonlinear dynamic loads in power systems
D. Karlsson,David J. Hill +1 more
TL;DR: In this article, an approach for experimental determination of aggregate dynamic loads in power systems is described, which can be expressed as nonlinear differential equations or equivalently realised in block diagram form as interconnections of nonlinear functions and linear dynamic blocks.

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.

Load modeling for power flow and transient stability computer studies
TL;DR: The LOADSYN load model synthesis software package as discussed by the authors transforms data on load class mix, composition, and characteristics into the form required for commonly used flow and transient stability simulation programs.

Voltage stability analysis using generic dynamic load models
Wilsun Xu,Y. Mansour +1 more
TL;DR: In this article, the authors investigated the dynamic nature of voltage stability using a generic load model representing the dynamic behaviour of aggregate loads, and revealed the mechanism of voltage collapse by examining the interaction of load dynamics with the supply network.
