Comparison of the ZIP load model and the exponential load model for CVR factor evaluation
2017 IEEE Power & Energy Society General Meeting, 2017Evaluating the effectiveness of Conservation Voltage Reduction (CVR) is a key challenge for utilities to determine the target feeder for voltage reduction deployment. In this paper, a time varying ZIP (TZIP) load model is developed to estimate the constant impedance, the constant current, and the constant power coefficients to calculate the CVR factor ...

Customer baseline load (CBL) calculation using exponential smoothing model with weather adjustment
2009 Transmission & Distribution Conference & Exposition: Asia and Pacific, 2009This paper proposes CBL calculation method that uses exponential smoothing model with weather adjustment multiplicative. It can estimate the daily electric load patterns of customers who participate in a demand response program. The proposed method is designed to estimate CBL using exponential smoothing model.

On unreliability of exponential load models
Electric Power Systems Research, 1999This paper addresses the issue of power system load modelling. In power system and voltage stability studies, only aggregate loads at high voltage buses are needed. Due to difficulties in determining appropriate load models at high voltage buses, the classical exponential static load model is still often used.

System reliability estimation for the Exponential load-strength model
Statistische Hefte, 1978A system comprising k identical components is considered. The system load that is common to all components is treated as a random variable, modeled by a one-parameter Exponential distribution. Each component's resistance to load is also taken as a random variable, modeled by another one-parameter Exponential distribution that applies to each component.

Wavelet-Exponential Smoothing: a New Hybrid Method for Suspended Sediment Load Modeling
Environmental Processes, 2019In this study, four conventional and a newly proposed method of wavelet-exponential smoothing (WES) - with two presented scenarios (WES1 and WES2) – are employed to estimate daily and monthly suspended sediment load (SSL) in two rivers (Lighvanchai river in Iran and Upper Rio Grande in the USA), which have different hydro-geomorphological ...

Conversion Error of Exponential to Second Order Polynomial ZIP Load Model Conversion
2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2018This paper presents two novel analytical methods for exponential to second order polynomial (i.e. ZIP) load model conversion. The load model conversion error of the proposed methods and three known methods is compared based on the results of conducted numerical analysis.

Applied Mechanics and Materials, 2014
According to optimized fitting analysis for measured data in static load test of 22 different types of single piles, a new modified exponential model was proposed by authors in this paper. In comparison between the hyperbolic model and the integrated exponential curve model, the correlativity coefficients R of the modified exponential model were over 0.
