The forecasting of building electricity demand is certain to play a vital role in the future power grid. Given the deployment of intermittent renewable energy sources and the ever increasing consumption of electricity, the generation of accurate building-level electricity demand forecasts will be valuable to both grid operators and building energy management systems. The literature is rich with...
This paper presents estimates of the customer-level demand for electricity by industrial and commercial customers purchasing electricity according to the half-hourly energy prices from the England and Wales (E&W) electricity market. These customers also face the possibility of a demand charge on its electricity consumption during the three half-hour periods that are coincident with E&W system p...
This chapter presents some results of an econometric analysis (developed in Patrick and Wolak 2001b) of customer-level demands for electricity of large and medium-sized industrial and commercial customers purchasing electricity under half-hourly spot prices and demand charges coincident with system peaks in the England and Wales (E&W) electricity market. These estimates can be used to forecast ...
Background: Rapidly increasing residential electricity demand has made raising energy efficiency an important policy issue in controlling electricity demand. Methods: This study uses a stochastic frontier model to estimate the residential electricity demand function and analyse electricity energy efficiency levels and their determinants using regional data on Japan. Results: The results confirm...
Recent efforts to restructure electricity markets have renewed interest in assessing how consumers respond to price changes. This paper develops a model for evaluating the effects of alternative tariff designs on residential electricity use. The model concurrently addresses several inter-related difficulties posed by nonlinear pricing, heterogeneity in consumer price sensitivity, and consumptio...
We propose a new approach to forecasting the demand for a commodity in which the commodity supplier asks each consumer to forecast its own demand for the commodity and in return gives a monetary reward that is proportional to the accuracy of the forecast. Such an approach might be applicable when consumer demand for a perishable commodity is uncertain and forecast error leads to waste for produ...
Proposing a novel interval-valued electricity demand forecasting approach. BEMD and SVR are integrated for interval forecasting of electricity demand. The EMD-based modeling framework are extended to deal with interval forecasting BEMD is used to decompose both the lower and upper bounds electricity demand series. The proposed modeling framework is justified with real world data sets....
Electricity demand and supply forecasts assume special significance vis-Ii-vis ever-increasing demand. Different agencies and authors, to forecast demand, have used various methodologies but on the other hand, no concerted effort is visible in predicting the supply. Moreover none of the methodologies used can be considered perfect. The present study attempts to forecast the two and tends to rea...
