Cooperation on the Public Notice on the Natural Gas Market Regulations No. 362/2009
Pelikán, Emil ; Vondráček, Jiří ; Konár, Ondřej ; Brabec, Marek ; Malý, Marek
We cooperate on the public notice on the natural gas market regulations No. 365/2009, namely on characterization of the customers with respect to the load profile assigning, calculation of the natural gas consumption using the load profiles, yearly consumption allocation for individual customers with meter reading of the type C and characterization of the load profile classes.
Experiences with Statistical Modeling of Natural Gas Consumption
Pelikán, Emil ; Brabec, Marek ; Malý, Marek ; Konár, Ondřej ; Vondráček, Jiří
This paper summarizes authors' experiences in mathematical modeling of natural gas consumption. Some issues related to the development, testing and implementation of several mathematical models are described. The paper is divided into four parts dealing with general questions of natural gas consumption modeling, examples of some statistical techniques, possibilities of their further development and factors affecting the quality of estimates.
Weather prediction in energy sector
Pelikán, Emil ; Brabec, Marek ; Brabec, Tomáš ; Eben, Kryštof ; Juruš, Pavel
In this contribution we summarize our experiences with a regional weather and air quality prediction system (called MEDARD), which is operationally used in the Institute of Computer Science in Prague. The system is based on the numerical weather prediction model MM5 and on the chemistry transport model CAMx. We discuss some applications of the system in energy demand forecasting and in other fields of energy industry.

Mathematical Modeling of Natural Gas Consumption in the Case of Residential and Small Commercial Customer
Konár, Ondřej
Natural gas consumption of households and small commercial customers is read from gas-meters usually once a year in the Czech republic. Every month a part (approximately 1/12) of customers is read. Hence there's always a certain amount of delivered natural gas which hadn't been invoiced yet. This amount needs to be estimated by a proper estimator. In this paper a nonlinear regression model GAMMA, which was developped in the Institute of Computer Science of AS CR is presented.
