Training departments need more tools to help them in the process of training operators. In addition, they also need more help in evaluating the training session. This creates an iterative process, whereby instructors can evaluate feedback and modify the training program appropriately to cover any holes identified, or identify the weaknesses of each trainee and help them perform better. The dispatcher training simulator (DTS) has already been recognized throughout the industry as one of the best tools to perform operator training. The authors have recognized that the actual philosophy of operator training will vary from utility to utility and will always be subjective in nature. However, one common factor in most training programs is the need to collect objective data which can be used to analyze trainee/training effectiveness and present this information in the form of a report. In this paper, the authors present a design and the results of a prototype implementation which will go a long way towards helping the instructor gather relevant data to evaluate the behavior of a power system during a training session. The training philosophy of a particular electric utility (Virginia Power) has been presented and the tool has been set up for it. The utilization of standard tools and methodologies in the design of this tool help in the ease of integration and usefulness of its outputs.","PeriodicalId":294493,"journal":{"name":"Proceedings of Power Industry Computer Applications Conference","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127083273","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 goal of this power system analysis function is to give the operator information about the static security status of the network. Technically this is achieved by running as many power flow cases as there are possible single element contingency scenarios in the network including lines, transformers and generators. Although no longer posing any mathematical problems, contingency analysis is a very critical function because of the overwhelming amount of information created during contingency analysis runs. In today's EMS, this problem is solved by giving tabular information indicating the overloads caused by which contingency. However, if there are overloads the operator does not get any support. There is no help offered as to which actions must be taken. Also the question of the underlying power system problem remains answered. There is usually no single best answer to this problem. This is recognized in this paper by describing a toolset based on image visualization and interaction of the whole set of data coming out of contingency analysis.","PeriodicalId":294493,"journal":{"name":"Proceedings of Power Industry Computer Applications Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121489068","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 use of artificial neural networks has been demonstrated as a valid alternative to classical statistical methods in terms of accuracy of results. However, a common architecture able to forecast the load in different geographical regions, showing different load shape and climate characteristics, is still missing. In this paper we discuss a heterogeneous neural network architecture composed of an unsupervised part, namely a neural gas, which is used to analyze the process in sub models finding local features in the data and suggesting regression variables, and a supervised one, a multilayer perceptron, which performs the approximation of the underlying function. The resulting outputs are then summed by a weighted fuzzy average, allowing a smooth transition between sub models. The effectiveness of the proposed architecture Is demonstrated by two days ahead load forecasting of L'Energie de L'Ouest Suisse (EOS) power system sub areas, corresponding to five different geographical regions, and of its total electrical load.","PeriodicalId":294493,"journal":{"name":"Proceedings of Power Industry Computer Applications Conference","volume":"50 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126071249","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}
