It is hoped that the resulting system will improve the quality of forecasting methods, through a better modeling of the nonlinear relationship between load and climatic factors. In view of the various aspects of the problem, the authors intend to develop a hybrid neural network (ANN)-knowledge based system (KBS) application: the ANN will form the basis of the system and will make the forecast in normal situations; the KBS should manage exceptions and special phenomena as well as provide specific knowledge-based facilities. The authors focus on the development of a prototype for the ANN. The ANN is to be a model of the evolution of the load w.r.t. input parameters, therefore the ANN predicts the ratio between the load for one day and the day before, instead of the raw load value.<<ETX>>","PeriodicalId":121897,"journal":{"name":"[1993] Proceedings of the Second International Forum on Applications of Neural Networks to Power Systems","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114299230","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 proposed prediction system learns 2-past-weeks data, consisting of the temperature at peak load, its difference from the previous day, the weather, and peak load on each day. Then it forecasts the rate of change in peak load for the following day, inputting the temperature, its difference, the weather and so on. Simulation results show that the average prediction error of the method is about 3%. The prediction error can be further reduced by, for example, changing the number of hidden layers and neural network parameters, such as the system temperature.<<ETX>>","PeriodicalId":121897,"journal":{"name":"[1993] Proceedings of the Second International Forum on Applications of Neural Networks to Power Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114804510","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 transient stability deals with the electromechanical oscillation of synchronous generators, created by a disturbance in the power system. For example, in the case of a transmission line fault, assume that faulted line section is first isolated and then reclosed (reclosure); there then exists a threshold parameter known as the stable critical clearing time (CCT). This paper describes a neural network based adaptive pattern recognition approach for estimation of the critical clearing time. Numerical examples are presented to illustrate this approach. In the neural network considered in this research work, a multi DSP-PC system (digital signal processor-personal computer system) is used for realizing faster backpropagation by applying pipeline operation and parallel operation.<<ETX>>","PeriodicalId":121897,"journal":{"name":"[1993] Proceedings of the Second International Forum on Applications of Neural Networks to Power Systems","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128944681","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}

Neural networks, though accurate in weekday load forecasting, are poor at forecasting maximum daily load, weekend and holiday loads. This necessitates development of a robust forecasting technique to complement the neural networks for enhanced reliability of forecast and improved overall accuracy. The statistical decision tree method produces robust forecasts and human intelligible rules. These rules provide understanding of factors driving load demand. Decision trees when combined with neural network forecasts, produce robust and accurate forecasts. Simulations are performed on a service area susceptible to large and sudden changes in weather and load.
