Offshore wind turbines, as a result of the harsher offshore environment, suffer from high O&M costs, and as such a high overall LCOE. These higher O&M costs can be reduced by focusing on the most critical subassemblies of the OWT, by either improving the reliability of the subassembly or by better understanding the failure mechanism, and thus optimizing the O&M strategy. The power converter is identified as one of the most critical subassemblies as risk of the operation of the OWT in terms of maintainability and availability. The reliability of the power converter is heavily influenced by both its steady-state and its dynamic thermal behavior, and as such great attention will be paid to the literature related to the thermal behaviour of the power converter. This paper seeks to provide a comprehensive overview on how the typical mission profile of an OWT influences the thermal loading. The paper seeks to propose a comprehensive and up-to-date literature review related to the lifetime modelling of the power converter, and to highlight some of the main challenges yet to be tackled in the reliability analysis of the power converter, suggesting future areas of research.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127629657","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}

To ensure the safety and stability of power systems, grid utilities often require renewable energy sources to be disconnected when an islanding condition exists. Such demands are becoming more strict due to the ever-expanding requirements on voltage ride through, frequency ride through, rate of change of frequency (ROCOF), and other functions so advanced anti-islanding techniques are required to quickly and accurately recognize an islanding condition and to stop the inverter. In this paper, slip mode frequency shift (SMFS) anti-islanding technique is verified using controller hardware-in- the-loop (C-HIL) real time simulation (RTS). It will be shown that the results from C-HIL RTS match the experimental results on the full scale inverter rated at 840 kW. The agreement between the experimental and C-HIL RTS results shows that this test can be performed using C-HIL without the need to test the hardware at full capacity.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114486654","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 goal of the study is to test analysis methods that enable remotely metered electricity consumption data to be used for automatically analysing the occupancy of buildings equipped with renewable energy generation. Pattern recognition techniques can be used for the purpose of occupancy detection. It was concluded that in many cases the moving average of a consumption pattern is sufficient to determine the fact whether people occupy the building or not, but the addition of on-site renewable energy production makes it more complex. The fact if there is renewable energy production in the building plays a critical role and has to be detected additionally, because it generates fluctuations on its own which have to be taken into account. The averaging time step of the available datasets is another aspect that influences the precision of the achieved detection results. The occupancy information can be used for different purposes, like researching the mobility of humans. In this case the results need to be aggregated to preserve the privacy of individuals.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116472277","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 power-voltage characteristic of photovoltaic (PV) modules shows multiple of local maximum power point when the modules are exposed to different irradiance levels. It is predicted that the local peaks are located near the multiples of 0.8 Voc, where Voc is .the open circuit voltage of the PV module. However, this prediction is not necessary correct especially with long string of PV modules exposed to lower irradiance level. It is most likely that the algorithm will deviate from the original peak locations and unnecessary scanning will be essential. Therefore, a new 0.8Voc model is proposed, which estimates the voltage at global maximum power point. By scanning the PV current on I-V characteristic curve to map out solar irradiance pattern, peak voltage and related deviation correction expressions are calculated. Afterwards, the position of the global peak voltage is estimated. The proposed algorithm is capable of exploiting the advantages of conventional 0.8Voc model, while improving its performance. The principles of design and theoretical analysis of the proposed algorithm are presented and its feasibility also validated by simulation for medium voltage megawatt photovoltaic (PV) system integration.","PeriodicalId":129367,"journal":{"name":"2020 9th International Conference on Renewable Energy Research and Application (ICRERA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122295652","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}
