This paper addresses the question of how much to bid maximize profit when trading in two electricity markets: hourly Day-Ahead Auction and quarter-hourly Intraday Auction. For optimal coordinated bidding many price scenarios are examined, own non-linear market impact is estimated by considering empirical supply demand curves, a number strategies used. Additionally, we provide theoretical result...

Cloud impacts on the transfer of Ultraviolet (UV) radiation through the atmosphere can be assessed using a cloud modification factor (CMF). The total global solar irradiation has proven to be a solid basis to derive CMF’s for the UV radiation (UV CMF). Total global irradiance is frequently measured and forecasted by numerical weather predic5 tion systems. Its advantage compared to for instance ...

Internet access traffic follows hourly patterns that depend on various factors, such as the periods users stay in the access point (e.g. at home or in the office) or their preferences for applications. The clustering of Internet users may provide important information for traffic engineering and tariffing. For example, it can be used to set up service differentiation according to hourly behavio...

The possibility to generate 2-D predictions of solar radiation one hour ahead and over a large geographic area is the focus of this study. In that view, hourly satellite maps of irradiations extracted from the Heliosat-3 have been used as training data and inputs of artificial neural networks (ANN) and as inputs for apersistence model. These models were computed for each point of the map, allow...

Unemployment Insurance (UI) wage records allow a detailed look at the functioning of the labor market.1 Researchers used this database to examine statistical and economic relationships between job and worker flows. For example, using UI wage records for the State of Maryland, S. Burgess and others found that new hires are not limited to expanding firms; separations are not limited to shrinking ...

Executive Summary This paper uses hourly data from industrial and commercial customers that volunteered to participate in Central and Southwest Service's (CSW) real-time pricing (RTP) programs to characterize the induced price response. The CSW RTP program, which adopted the two-part, revenue neutral design first introduced by Niagara Mohawk, was introduced to large commercial and industrial cu...

BACKGROUND Epidemiological studies have shown adverse effects of short-term exposure to air pollution on respiratory disease outcomes; however, few studies examined this association on an hourly time scale. We evaluated the associations between hourly changes in air pollution and the risk of respiratory disease in the elderly, using the time of the emergency call as the disease onset for each c...

This study evaluates the validity of Integrated Multisatellite Retrievals for Global Precipitation Measurement (IMERG) in scaling extreme precipitation with temperature (termed factor, SF). To this end, we use Hadley-Integrated Surface Database (HadISD) data set at 1-hourly, 6-hourly, and 24-hourly scales between 2000 2020 over contiguous United States (CONUS) as a reference set. Our findings r...

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 ...

In Shenandoah National Park, O(3) monitoring data were characterized and attempts were made to relate O(3) concentration levels to visible foliar injury observed for five plant species surveyed. Foliar injury for three species increased with elevation. The 24-h monthly mean O(3) concentrations tended to increase with elevation; however, the number of elevated hourly occurrences did not. Althoug...
