The features of maximum power point tracker based on conventional hill-climbing algorithm are studied. The new controller incorporates the advantages of hill-climbing algorithm and eliminates its drawbacks. This technique provides fast and accurate convergence to the maximum power point during steady-state and gradually changing weather conditions. The hill-climbing algorithm is implemented using 17 fuzzy control rules. Simulation results are provided to illustrate the validity of the proposed hill-climbing based fuzzy-logic controller.","PeriodicalId":176900,"journal":{"name":"2013 International Conference on Power, Energy and Control (ICPEC)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132872975","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 trust-region-doleg method is proposed here for extraction of five parameters such as series resistance (Rs), shunt resistance (Rp), diode ideality factor (a), dark saturation current (I0) and photo-generated current (Ipv) under standard test conditions (STC). The comparative analysis is made by taking Villalva's iterative method and proposed trust-region-dogleg method. Two parameters Rs and Rp are extracted by Villalva's iterative method whereas all five unknown parameters can be extracted by proposed trust-region-dogleg method. The accuracy of parameters calculation depends on tolerance band and initial conditions are tabulated.

The problem is to minimize the number of PMUs required for network observability and to maximize the PMU measurements redundancy. This is achieved by selecting a solution with maximum System Observability Redundancy Index (SORI)if multiple optimal solutions exist. The resulting nonlinear integer programming (NLIP)problem is solved by the proposed DE method for the optimal solution by considering different power system problems viz. a 7-bus test and IEEE 14-bus systems with and without the consideration of zero injection buses. Results thus obtained have also been validated with existing solution techniques.","PeriodicalId":176900,"journal":{"name":"2013 International Conference on Power, Energy and Control (ICPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128414778","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}

It gives a large range of performance variation. In order to make it suitable for the purpose the index is proposed, which along with NEMA definition can be utilized for the reduction of voltage variation and exact assessment of performance of induction motor. The performance of this index along with the NEMA definition is tested for various motor performance indices such as peak stator current, derating factor. The variations in the performance of the motor can be reduced with suggested voltage unbalance index. These facts are investigated by conducting various experiments on MATLAB Simulink software package.","PeriodicalId":176900,"journal":{"name":"2013 International Conference on Power, Energy and Control (ICPEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125980824","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}
