The device performs measurement in 32 levels and for each level an electric voltage curve is generated; the combination of the 32 curves forms a data matrix that characterizes the soil sedimentation behavior. The matrix is then subjected to classification by pattern recognition by neural network perceptron of multiple layers; previously trained with reference samples. The neural network classifies the soil texture by identifying the probabilities of the sample being tested as one of the reference samples.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"11 4 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83409587","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 such a situation, increasing operational flexibility is the main way to cover wind power unpredictability and to enable secure operation of the power system. To this end, this paper proposes a flexible security-constrained program to schedule supply-side and demand-side via an optimal pricing and incentive scheme. The considered demand response (DR) programs include time of use (TOU), real-time pricing (RTP), critical peak pricing (CPP), as well as emergency demand response program (EDRP). The study aims to find the most effective DR scheme among a set of DR programs to improve the efficiency of electricity markets while guaranteeing the security and environmental restrictions through minimization of two objective functions, the ISO's operational cost and pollutant emissions from generation units.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"58 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82907549","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 algorithm is executed by modelling a biased differential characteristic and developing algorithms for security issues in a transformer considering the most predominant system conditions i.e. inrush condition during transformer energization and CT saturation during heavy through fault conditions. Detection of inrush currents were performed using statistical analysis of differential power and using a discrimination index. CT saturation detection is independent of current waveform analysis and is based on the calculation of the saturation time. The proposed algorithms are evaluated and validated under different scenarios using MATLAB/Simulink environment and investigative study is performed. The results are visualized as current trajectories plotted on the relay operating characteristics summarized for easy conception of the algorithm.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"33 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82860158","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}

Everyone is exposed to Sun but some outdoor workers categories are exposed not only in their leisure time but also during their working activities. To protect outdoor workers health, daily estimates of UV radiation are needed and without a national service providing a measured UV Index (UVI) in the Italian territory, UVI forecasting methods are welcomed. Forecasting methods can be classified in two major groups: methods based on the estimation of the UV total irradiance from solar total irradiance and methods based on regression models of measured UVIs. The former have greater uncertainties (about 30%) and are more suitable for epidemiologic studies, the latter, due to their better precision (about 10-20%), are more suitable for daily UVI evaluation.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"311 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82902030","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 will be determined and will be taken into account the influence that certain parameters of the circuit have on some more important features. In order to obtain optimal performance, conditions will be imposed and relations that the quantities must verify will be derived. Two cases of practical utility were analyzed in detail: the case of two coupled coils in series and the case of the magnetically coupled coils used in wireless power transfer. The imposed condition referred to obtain a maximum value for the power transmitted to the load, respectively for the current through it. This has resulted in various relations and restrictions imposed on the parameters of the circuit.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"30 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90350031","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 conversion accuracy of the proposed analytical methods was found to be better than the accuracy of previously known analytical conversion method. In some cases, the conversion error of proposed methods was comparable to non-linear least squares conversion results. It is also shown that the load model conversion error depends on the used conversion method, exponential load model parameter values and the voltage used for error calculation.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"9 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89612860","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 model of a grid-connected PV-diesel microgrid is enhanced, and new practical constraints are added. In addition, a new mixed-integer nonlinear programming (MINLP) problem is formulated to optimize the power flow in the microgrid for covering the load while minimizing the power consumption cost as well as maximizing the dispatched power from the PV-array. To demonstrate the applicability of the developed model and the optimal operation strategy, a comparison between different system configurations is made. The results show that the proposed microgrid can reduce the dispatched power cost while decreasing the power curtailment from the PV-array. Moreover, installing multiple diesel generators (DGs) can significantly reduce the fuel consumption by the DGs in comparison to a single DG in the PV-diesel microgrid.","PeriodicalId":6563,"journal":{"name":"2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe)","volume":"45 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87900420","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}
