The computer industry has been evolving continuously, and the power industry, which remained relatively stable for decades, is now undergoing revolutionary changes that require the special attention of EMS developers. The introduction of new players, the decentralization of production and processing of information, and competition will change the way control centers operate and, consequently, their architecture. Distinct areas of computer science have suggested many different approaches to tackle the problems that arise in the new decentralized scenario. Of particular interest, agent technology, proposed in the context of distributed artificial intelligence, is a very promising approach to support the construction of a new generation of EMS in an open environment.","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115265427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Competition between numerous utilities leads to the necessity to optimize the operation of power plants and networks, i.e., to decrease the operation costs and to increase the reliability of the equipment. A new generation of simulation and training software workshops is necessary to keep abreast of this evolution. CORYS T.E.S.S. and Tractebel Energy Engineering responded to these new challenges by developing the ALICES software workshop. This article shows that modeling and simulation can contribute to providing the answers to the industry's new challenges. The article begins with an economical justification for simulation and training, focuses on the new generation of simulation software tools, and ends with several case studies to show how the tools are being used in the field.","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114928805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Haldorsen","doi":"10.1109/67.849021","DOIUrl":"https://doi.org/10.1109/67.849021","url":null,"abstract":"City streets cover a complex array of underground electric, gas, and communication lines. Effective maintenance, expansion, and new installation of these networks require accurate information regarding the location of the conduits, cables, and other structures that lie beneath the surface. Underground maps, if they exist, are often inaccurate, incomplete, or out of date, and attempts to find underground lines or obstacles using metal locators often prove disappointing. To help companies create accurate maps of subsurface networks, researchers have developed a new ground-penetrating imaging radar (GPIR) system that creates sharp, three-dimensional (3-D) images of underground lines and objects. Schlumberger Corporation, in conjunction with the Electric Power Research Institute (EPRI) and the Gas Research Institute, has developed a GPIR system that detects, locates, and produces 3D maps of underground features. The new underground imaging system holds the potential to reduce utility operating and maintenance costs by avoiding unneeded excavation and by reducing incidences of costly damage such as ruptured gas lines. Field demonstrations in New York City, San Diego, and other utility locations have proven the ability of the new mapping system to create accurate images of objects in crowded urban areas at depths as great as 10 ft (3 m).","PeriodicalId":435675,"journal":{"name":"IEEE Computer Applications in Power","volume":"5 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131550592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The means to input, process and extract the data from the simulation is termed the solution domain.
