In the proposed method, the output side of the matrix converter behaves as a resistor for the source current and the input side of the matrix converter compensates reactive power of the squirrel-cage induction machine. Digital computer simulation is implemented to confirm the validity and practicability of the proposed method using PSCAD/EMTDC. Simulation results demonstrate that the proposed inrush current suppressor can suppress the inrush current drastically.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128106815","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 is of great importance to optimize the electricity generation system to install for each household. In our previous work, we proposed a clustering approach for extracting a small number of basic electricity consumption patterns in a household. In this study, we apply the method to a larger dataset with many households. In the previous work, we determined the number of basic patterns in a heuristic manner. In this work, we use gap statistics to automatically determine an appropriate number of basic patterns, and we obtained a reasonable result on a large-scale data.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124108752","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 case of ETBE synthesis, at a microwave power of 350W, and irradiation time of 1 min, the mixture reached solvothermal conditions obtaining EtOH conversion closed to 90%. The conversion and yield were found to be dependent on operating parameters such as temperature, microwave irradiation power, time and amount of catalysts.

A simple extension of pattern sequence-based forecasting (PSF) enables us to predict demand curves based on the correlated bidimensional time-series by using co-occurrence patterns of energy supply and demand. However, prediction accuracy of PSF deeply depends on the clustering result, which is used for pattern matching. In this paper, a promising clustering method based on nonnegative tensor factorization is applied for this task and evaluated experimentally from the viewpoint of prediction accuracy.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130590651","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 Polycity project represents a significant demonstration of this energy policy, which was applied to 3 cities: Barcelona, Stuttgart and Torino. The case of Torino appears of particular relevance because it is dedicated to the improvement of energy performance of existing buildings and installations which is, in our opinion, the most frequent situation. In particular the most qualifying characteristic of Torino project is the installation of a new combined heat and power generator (CHP), coupled with an absorption chiller, in order to supply energy more efficiently in a district which include the Housing Authority of the Province of Torino (ATC) building and 30 council buildings. The trigeneration plant is able to supply electricity and cooling power to the main office building and, thanks to the coupling to the existing district heating system, it provides thermal energy for space heating and hot water to the council buildings in the district. The paper reports the analysis activities performed during Polycity project to understand the role of monitoring and control in a complex energy system with the aim of improving the efficiency and reducing the energy consumption also in the BECA project.","PeriodicalId":239142,"journal":{"name":"2012 International Conference on Renewable Energy Research and Applications (ICRERA)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117343756","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}
