Optimal Coefficient Selection of Exponential Smoothing Model in Short Term Load Forecasting on Weekdays [PDF]

open access: yesThe Transactions of The Korean Institute of Electrical Engineers, 2013
Short term load forecasting for electric power demand is essential for stable power system operation and efficient power market operation. High accuracy of the short term load forecasting can keep the power system more stable and save the power market operation cost.

Analysis of Coupling Effect and Heavy Load of High-Temperature Stability of Asphalt Mixture

open access: yesAdvances in Materials Science and Engineering, 2022
To study the variation in the high-temperature stability of asphalt mixtures under extreme high temperature and heavy load, rut tests and analyses were carried out with both the APA (asphalt pavement analyzer) test and CLWT (Chinese wheel load test).

Data-Driven Diagnostics of Mechanism and Source of Sustained Oscillations [PDF]

open access: yes, 2015
Sustained oscillations observed in power systems can damage equipment, degrade the power quality and increase the risks of cascading blackouts. There are several mechanisms that can give rise to oscillations, each requiring different countermeasure to ...

Empirical assessment of VoIP overload detection tests [PDF]

open access: yes, 2010
The control of communication networks critically relies on procedures capable of detecting unanticipated load changes. In this paper we explore such techniques, in a setting in which each connection consumes roughly the same amount of bandwidth (with ...

Measurement-Based Current-Harmonics Modeling of Aggregated Electric-Vehicle Loads Using Power-Exponential Functions [PDF]

open access: yesWorld Electric Vehicle Journal, 2020
This paper presents an aggregate current-harmonic load model using power exponential functions and built from actual measurement data during the individual charging of four different fully electric vehicles. The model is based on individual emitted current harmonics as a function of state of charge (SOC), and was used to deterministically simulate the ...
