This paper presents a novel method based on growing and pruning training algorithm using radial basis function neural network (GPRBFNN) and winner-take-all neural network (WTA) to examine whether the power system is secure under steady-state operating conditions. Hidden layer neurons have been selected with the proposed algorithm which has the advantage of being able to automatically choose optimal centers and distances. A feature selection technique-based class separability index and correlation coefficient has been employed to identify the inputs for the GPRBF network. The advantages of this method are simplicity of algorithm and high accuracy in classification. The effectiveness of the proposed approach has been demonstrated on IEEE 14-bus and IEEE 30-bus systems.","PeriodicalId":393869,"journal":{"name":"2010 IEEE Electrical Power & Energy Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116493241","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 integrated hydro-thermal systems considered include fixed-head hydro reservoirs. The short-term hydro-thermal scheduling (STHTS) problem is a dynamic large-scale nonlinear optimization problem which requires solving unit commitment and economic power load dispatch problems. The bacterial foraging algorithm (BFA) is a recently developed evolutionary optimization technique based on the foraging behavior of the E. coli bacteria. The BFA has been successfully employed to solve various optimization problems; however, for large-scale problems such as this problem, it shows poor convergence properties. To overcome this problem considering its high-dimension search space, critical modifications are introduced to the basic BFA. The algorithm presented is validated using two fixed-head test systems. Results show that the proposed algorithm is capable of solving the problem with good performance.","PeriodicalId":393869,"journal":{"name":"2010 IEEE Electrical Power & Energy Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115361413","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}

However, they disturb the radial nature of the network and thus give rise to many problems. Unintentional islanding is one of the encountered problems. In this paper a neuro-wavelet islanding detection technique has been developed. The method is based on the transient voltage signals generated during the islanding event. Discrete wavelet transform is adopted to extract feature vectors which will then be fed to a trained artificial neural network classifier to classify the transients generated as islanding or non-islanding events. The trained classifier was then tested using novel voltage signals. The test results indicate that this approach can detect islanding events with a good degree of accuracy.","PeriodicalId":393869,"journal":{"name":"2010 IEEE Electrical Power & Energy Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129809700","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}

This triggered us to design a novel Hybrid Fibre Optic Lighting System. The proposed system relies on the fact that light rays are free and can be harnessed without the use of expensive tracking systems requiring constant alignments. A successful system must respond to the following criteria. The collector should be fixed and capable of collecting as much sunlight as possible during a sunny day, taking into account any external obstacle. The system has to be robust to withstand all weather conditions and have an efficiency equivalent to that of standard lighting requirements. A control system to turn lighting on/off as needed would be advantageous.","PeriodicalId":393869,"journal":{"name":"2010 IEEE Electrical Power & Energy Conference","volume":"1051 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116467516","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}

Wind energy and tidal energy are two popular forms of renewable energy. The variation of output power with the continuous variation of tides or wind speed can cause significant power quality issues. This paper studies a network presenting a rural load, such as a small village, fed from a hybrid wind/tidal turbines that are connected to a weak grid. The effect of the variation in tides and wind speed on the power quality is illustrated via simulation. The introduction of the Modulated Power Filter Compensator (MPFC) to the network establishes a significant improvement to the power quality. The proposed MPFC is a cheap and robust FACTS based device. It is controlled via a tri-loop dynamic error-driven PI controller. This scheme proved its ability to introduce a significant improvement which is illustrated via comparing the simulation results of the studied network with and without the MPFC.","PeriodicalId":393869,"journal":{"name":"2010 IEEE Electrical Power & Energy Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125736702","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}
