Experimental data generally contain measurement noise. In this paper, review on modelling photovoltaic (PV) module/array is established first; next, the combination of the optimization method of maximum likelihood estimator (MLE) and Newton Raphson resolution for identifying the five unknown parameters of single diode photovoltaic Module/Array at different types of test conditions is proposed. This predicted method is compared with generalized least square estimator known also as optimization method. It is also compared with popular predictive methods Villalva's and Lambert solution. The proposed method is applied for polycrystalline silicon photovoltaic MSX60 solar module at standard test condition (STC). Two types of comparison are made: first, the dynamic variations of all five parameters values are carried out by graphs and compared in tables with the values found with the other methods (mentioned above); the parameters have converged after up to 150 iterations at STC and the accuracy of estimated parameters is sensitive to the initial parameters of trust region. Secondly, the (I-V) curves are superposed, justifying the accuracy of the proposed method. The comparative errors graphs are also carried out. The results proved the effectiveness of the maximum likelihood estimator, by accuracy parameters of the PV module/array.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128264962","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 mathematical models of the three-phase induction motor are implemented in LabViewblock diagram pages. These models are in form of differential equations and Runge-Kutta 4th order method is implemented to solve the problem. LabViewFpga module alongside with Xilinx 10.1 compiler will generate the Bitfiles, and then Synthesize, Route and place the logic gates to a FPGA chip. NI PCI-7831R is programmed to communicate with real system as a data acquisition card. This communication is implemented in real time environment (RTX) through Ardence RTX as a multithread and multitasking software. The presented real-time platform provides a versatile and flexible simulation tool for investigating dynamic behaviors of induction machine in different cases and can be extended to many other equipment and subsystems of electrical power systems. To validate implemented squirrel cage induction motor model and also its behavior in LabViewsoftware, human machine interface (HMI) is developed in LabViewfront page. A study case is simulated in LabViewreal-time system and MATLAB/Simulink, as two independent software. Results show that motor characteristics (i.e. speed, torque, and etc.) are in the close correspondence compared to MATLAB outputs and consequently LabVIEW model is verified.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132168825","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}

Solar energy for electricity generation is popular and widespread as it is clean and abundantly found in nature. Partial shading on solar photovoltaics directly affects performance by reducing the power output of the system. As a contribution to further developments in photovoltaic technologies, factors that affect the performance of photovoltaics, under partial shading conditions were studied to improve the technology. Currently available strategies include the use of bypass diodes, Centralized Maximum Power Point Tracking, Distributed Maximum Power Point Tracking as solutions. Comparison of these methods were done and observed that Distributed Maximum Power Point Tracking gave the optimum solution. A DC-DC converter along with a Maximum Power Point Tracker was interfaced at each PV module which enabled the Maximum Power Point to be tracked. In this paper, a novel algorithm is proposed for optimal configuration of solar panels under partial shading conditions. The simulations were done in Matlab/Simulink.","PeriodicalId":265297,"journal":{"name":"2018 IEEE Electrical Power and Energy Conference (EPEC)","volume":"98 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120858605","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}
