Short Term Load Forecasting Technique Based on the Seasonal Exponential Adjustment Method and the Regression Model

Energy Conversion and Management, 2013
Abstract For an energy-limited economy system, it is crucial to forecast load demand accurately. This paper devotes to 1-week-ahead daily load forecasting approach in which load demand series are predicted by employing the information of days before being similar to that of the forecast day.

Comparison of the ZIP Load Model and the Exponential Load Model for CVR Factor Evaluation

2017 IEEE Power & Energy Society General Meeting, 2017
Evaluating 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 ...

On unreliability of exponential load models

Electric Power Systems Research, 1999
This 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.

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), 2018
This 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.

System reliability estimation for the Exponential load-strength model

Statistische Hefte, 1978
A 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.

Electricity Load Forecasting Using Hybrid of Multiplicative Double Seasonal Exponential Smoothing Model With Artificial Neural Network

Jurnal Teknologi (Sciences and Engineering), 2014
Electricity load forecasting often has many properties such as the nonlinearity, double seasonal cycles, and others those may be obstacles for the accuracy of forecasting using some classical statistical models. Many papers in this field have proposed using double seasonal (DS) exponential smoothing model to forecast.
