But due to the complexity of the influence factors, the sensitivity analysis on electricity price is along one of focused and unsolved problems in the researches of electricity market. To solve this problem, a novel model is proposed to analyze the sensitivity of electricity price. The basic and first work here is to mine the quantity explanatory equation of electricity price, which is built based on hybrid algorithm that integrates support vector machine (SVM) with regression. To enhance the accuracy and adaptibility of price model, SVM is applied for price pattern identification. And different regression models are built in terms of their corresponding patterns. After that, the derivatives of all explanatory variables in the equation are computed. Then the sensitivity coefficients of price are obtained. Finally case studies are used to testify the validity of the proposed model.","PeriodicalId":231682,"journal":{"name":"2007 2nd IEEE Conference on Industrial Electronics and Applications","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116847230","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}

In order to solve these practical application problems, a novel model of one-class bearing fault detection based on SVDD and genetic algorithm is presented in this paper. The time domain statistics features are processed as inputs to SVDD for one-class (normal) recognition. Then SVDD is used to describe the normal data distribution characteristics with high data description ability. The SVDD is trained only with a subset of normal samples. This paper also analyzes the behavior of the classifier based on parameter selection and proposes a novel way based on genetic algorithm to determine the optimal threshold parameters. The hybrid one-class classification model of SVDD and genetic algorithm is determined to address the problem of difficultly collecting abnormal samples in bearing fault detection. Comparison of the performance of detection of SVDD with different kernel parameters is experimented. This hybrid approach is compared against other MLP detection techniques. The results show the relative effectiveness of the proposed classifiers in detection of the bearing condition with some concluding remarks.","PeriodicalId":231682,"journal":{"name":"2007 2nd IEEE Conference on Industrial Electronics and Applications","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117005671","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}

Active clamp circuit can help the switching devices in the Cuk converter to be operated at zero voltage switching (ZVS) turn-on. Therefore this converter is suitable for high frequency operation to reduce the size of reactive components. The clamp capacitor and auxiliary switch are connected in parallel with the primary switch. When main switch is turned off, the positive inductor current will flow through the anti-parallel diode of auxiliary switch. At this instant, the auxiliary switch can turn on at ZVS. On the other hand, the resonance between the resonant inductor and output capacitor of main switch will create a ZVS condition for main switch. The principle of operation, system analysis, and design consideration are presented in this paper. Experimental results for a laboratory prototype rated at 400 W, input voltage of 150 V~300 V, output voltage of 200 V, and operating at 105 kHz are given to demonstrate the effectiveness of the proposed converter.","PeriodicalId":231682,"journal":{"name":"2007 2nd IEEE Conference on Industrial Electronics and Applications","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129631507","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}
