Power delivery systems are composed of generation, transmission and distribution system networks, loads, control and management systems. In the effort of providing a clean electric power to the consumer not only the energy sources need to be reformed but also all the above components have to be considered simultaneously using Information and Communication Technology (ICT) to reduce cost, save energy,...
This paper presents the results for daily load forecasts of a local power supplier. The new approach of this paper is to use three neural networks, each representing a period of a day, for the daily load forecast. Three commercial tools for neural networks are used to reduce the time for the development and tests. The neural networks are tested with real load values of a the power supplier for a period...
An analytic operation strategy calculates the operation points for the combustion engine and the electric motor following a cost function to minimize the fuel consumption. To increase the lifetime of batteries the state of charge (SOC) range used should not be bigger than 10%. The limited usable SOC range and the low fuel consumption are conflicting goals. This paper shows that the cost function can...
This paper describes an aspect of the future SCADA system for power systems application in a context of the penetrating distribution generation (DG) system and potential of the renewable energy into future electricity infrastructure or power grid. This penetration of DG and Renewable energy sources (RES) will be a big challenge for the existing infrastructure of the power systems. Decentralized energy...
In modern society, energy production is one of the most critical issues all over the world. In order to generate cleaner, more reliable and ecological friendly energy, integrating of the whole power system which disperse in a wide area is very important. By integration of such geographically dispersing power system as a single substance, huge database and computational intensive processing is of necessary...
This paper will give an overview of the status of Web-based learning for power engineering in the world. The descriptions will include the concepts of power engineering programs study using Web-based learning typical to different countries. Use of advance presentation methods (multimedia, videos, etc.) and application of computers in power engineering education will be discussed. In order to demonstrate...
This paper shows a possibility of the combination of renewable energy sources and water desalination in a self-contained installation. There is a chance to combine both aspects to save our climate and to solve the problem of water shortage in many countries, especially in countries with a high sun radiation, like in Africa as well in northern industrial countries with less sun radiation. One option...
Power generation monitoring and control systems for nuclear plant can contribute even to further risk by lack of training. The training can be improved by remote control and monitoring of a training module, e.g. based on web-technology. Remote control and monitoring has been the subject of much research works over many years. There remains, however, much scope for the training of operators.
The need for renewable power generation in power systems is becoming more importance. This need requires geographically-distributed power systems to be integrated as a single entity where among the main features of this integration are large data base and computing intensive. Grid Computing is a gateway to virtual storage media and processing power, this paper describes how grid computing can be utilized...
Power load forecasting is the problem which is solved in this paper under MATLAB environment by constructing a neural network for the power load to find simulated solution with the minimum error square. MATLAB code has been programmed for approximating power load data by using the radial based function (RBF) neural network with Gaussian basis function (GBF's). A developed algorithm to achieve load...
The importance of renewable energy resources are growing because of many reasons including the increasing costs of fossil fuels and the growing awareness of sustainability and environmental concerns. There are many different possibilities to use renewable energy systems in the domestic housing sector like photovoltaic for electrical power or solar collectors for thermal energy to provide space heating...
The German electricity market has changed from monopoly to oligopoly and is currently dominated by four leading electricity providers. Thus, it can be hardly argued that the German market represents the ideal vision the EU might had when introducing the electricity directive in 1996. In this paper the influences responsible for the dramatic raise of the wholesale prices for electricity in Germany...
