Apparently, some inverters have been optimized for high irradiance levels \r\nand ranked better at the CEC efficiency ranking, others performed very well also at low irradiance levels, thus \r\nranking higher at in the EU efficiency ranking. Efficiency ranks are slightly deviating from rankings by energy yield \r\nmeasurements. At one inverter, a slow MPPT algorithm that barely could follow quickly changing irradiance levels is \r\nmost probably responsible for this effect. Another inverter switched off for a while after operation at high power, \r\nanother one failed permanently. Apparently, some inverters are been optimized to show excellent datasheet ratings \r\nfor EU- or CEC- efficiency. On the other hand, two inverters (each featuring two inputs) did not show an outstanding \r\nperformance at the EU- and CEC-ratings but achieved leading ranks for AC energy yields. For the customer, AC \r\nyield is a major performance indicator of a microinverter and should be included in the datasheet.","lang":"eng"}],"publication":"Proceedings of the EUPVSEC 2020","citation":{"bibtex":"@inproceedings{Krauter_Bendfeld_2020, title={Micro-Inverters: An Update of Comparison of Conversion Efficiencies and Energy Yields}, DOI={<a href=\"https://doi.org/10.4229/EUPVSEC20202020-4DO.7.2\">10.4229/EUPVSEC20202020-4DO.7.2</a>}, booktitle={Proceedings of the EUPVSEC 2020}, author={Krauter, Stefan and Bendfeld, Jörg}, year={2020}, pages={935–938} }","ama":"Krauter S, Bendfeld J.

Due to the present \r\ninflexibility and the lack of sufficient throttling capabilities of lignite and nuclear power plants, a surplus of \r\nelectricity generation occurs during periods of high wind and solar power generation. While the specific CO2-\r\nemission is decreasing then ‒ due to the increased share of Renewables, the grid frequency is increasing (to a certain \r\nlimit). Using the grid frequency as an indicator to switch-on and off certain loads (loads that do not require power \r\npermanently (e.g. dishwashers, washing machines, dryers, fridges and freezers, heaters) could provide a simple, \r\ninexpensive demand-side management indicator to lower specific CO2‒emssions and costs (if a dynamic \r\nconsumption tariff is available). To check the truthfulness of that hypothesis, the grid and frequency data of the \r\nGerman grid of the year 2018 have been collected and a the correlation between grid frequency, power surplus, share \r\nof renewables vs. CO2-contents and price at the European energy exchange (EEX) have been calculated. The results \r\nshow: Correlation between frequency and share of renewables is quite low (r = 0.155) due to the fact that primary \r\ngrid control quickly compensates deviations from the 50 Hz nominal frequency. There is a good anti-correlation (r = -\r\n0.687) between the EEX‒prices and the share of renewables in the grid. Over the years, correlation between \r\nelectricity trading prices (EEX) and CO2 emissions is quite good (r =0.665), within the one year (2018) that \r\ncorrelation almost doesn’t exist, possibly due to the inflexibility of the bulky lignite power plants that even operate at \r\nnegative prices. \r\n","lang":"eng"}],"publication":"Proceedings of the 37th European Photovoltaic Solar Energy Conference, 07 - 11 September 2020.","keyword":["Keywords: Load-Shifting","Demand-Side-Management","DSM","grid frequency","EEX","electricity trading prices","renewable share","flexibility","emissions","CO2"],"type":"conference","department":[{"_id":"53"}],"file":[{"date_updated":"2022-01-06T12:35:49Z","relation":"main_file","file_size":1309449,"access_level":"closed","file_name":"Krauter Zhang - Triggering DSM - EUPVSEC 2020.pdf","content_type":"application/pdf","success":1,"file_id":"29172","creator":"krauter","date_created":"2022-01-06T12:35:49Z"}],"date_created":"2020-09-14T12:43:43Z","date_updated":"2022-01-06T12:42:22Z","publication_status":"published","year":"2020","title":"Triggering Demand‒Side‒Management: Correlation of electricity prices, share of renewables, CO2‒contents, and grid‒frequency in the German electricity grid.","publication_identifier":{"issn":["\t3-936338-73-6"]},"author":[{"orcid":"0000-0002-3594-260X","first_name":"Stefan","last_name":"Krauter","full_name":"Krauter, Stefan","id":"28836"},{"full_name":"Zhang, L.","last_name":"Zhang","first_name":"L."}],"doi":"10.4229/EUPVSEC20202020-6BV.5.9","language":[{"iso":"eng"}],"quality_controlled":"1","file_date_updated":"2022-01-06T12:35:49Z","citation":{"ama":"Krauter S, Zhang L.

While the specific CO2-emission is decreasing then - due to the increased share of Renewables, the grid frequency should be increasing (to a certain limit). Using the grid frequency as an indicator to switch-on and -off certain loads (loads that do not require power permanently (e.g. dishwashers, washing machines, dryers, fridges and freezers, heaters) could provide a simple, inexpensive demand-side-management indicator to lower specific CO2-emissions and costs (if a dynamic consumption tariff is applied). To check the truthfulness of that hypothesis, the grid and frequency data of the German grid of the year 2018 have been collected and the correlations between grid frequency, share of renewables, CO2-contents, and actual price at the European energy exchange (EEX) have been calculated. The results show: Correlation between grid frequency and the share of renewables is quite low (r=0.155) due to the fact that primary grid control quickly compensates deviations from the 50 Hz nominal frequency. As expected, there is a good anti-correlation (r=-0.687) between the EEX-prices and the share of renewables in the grid. Over the years, correlation between electricity trading prices (EEX) and CO2 emissions is quite good (r=0.665), within the one year (2018) that correlation almost doesn't exist, possibly due to the inflexibility of the bulky lignite baseload power plants that even operate at negative prices.","lang":"eng"}],"publication":"Proceedings of the 47th IEEE Photovoltaic Specialists Conference (PVSC 47) 2020","type":"conference","keyword":["CO2","EEX","Grid frequency","DSM","electricity price","Renewable share"],"department":[{"_id":"53"}],"date_created":"2020-09-14T12:39:41Z","date_updated":"2022-01-06T13:52:16Z","year":"2020","title":"Correlation of grid-frequency, electricity prices, share of Renewables and CO2-contents of German electricity grid to enable inexpensive triggering of Demand-Side-Management","author":[{"id":"28836","last_name":"Krauter","orcid":"0000-0002-3594-260X","first_name":"Stefan","full_name":"Krauter, Stefan"},{"first_name":"L.","last_name":"Zhang","full_name":"Zhang, L."}],"corporate_editor":["IEEE"],"doi":"10.1109/PVSC45281.2020.9300487","main_file_link":[{"url":"https://ieeexplore.ieee.org/document/9300487"}],"language":[{"iso":"eng"}]},{"title":"Comparison of Microinverters: Update on Rankings of Conversion Efficiencies and Energy Yields","year":"2020","publication_identifier":{"issn":[" 0160-8371"]},"author":[{"id":"28836","orcid":"0000-0002-3594-260X","first_name":"Stefan","last_name":"Krauter","full_name":"Krauter, Stefan"},{"id":"16148","full_name":"Bendfeld, Jörg","last_name":"Bendfeld","first_name":"Jörg"}],"date_updated":"2022-01-07T10:10:43Z","publication_status":"published","main_file_link":[{"url":"https://ieeexplore.ieee.org/document/9300953"}],"language":[{"iso":"eng"}],"doi":"10.1109/PVSC45281.2020.9300953","publication":"Proceedings of the 47th IEEE Photovoltaic Specialists Conference (PVSC 47) JUNE 15 - AUGUST 21, 2020 VIRTUAL MEETING","abstract":[{"text":"To compare efficiency and yield of many micro-inverters available on the world market in 2014-2020, an in- and outdoor test laboratory at the University of Paderborn has been set up. The inverters have been fed by identical and calibrated crystalline silicon PV modules of 215 Wp. To monitor accurately DC input, AC power output and energy yield, each of the micro-inverters has been equipped with a calibrated electricity meter. For micro-inverters requiring control units for grid-feeding that has been acquired also. The comparison covers efficiency-load characteristics as well as electrical energy yields. Purchase costs vary considerably between the models in comparison, sometimes inverter costs are higher than module costs, particularly if an additional grid-connection or interface device is needed for operation. The weighted conversion efficiency according to EU and CEC standards has been measured and calculated. While some inverters have been optimized for high irradiance levels, they ranked better at the CEC efficiency, others performed very well also for low irradiance levels, thus ranking higher at in the EU-efficiency tables. These results are deviating from the actual energy yield measurements, which show a slightly different ranking. At one inverter, an accurate, but very slow MPPT algorithm that barely could follow quickly changing irradiance levels could be the reason for this effect. Another inverter switched off after operation at high power output for a while. Apparently, some inverters are been optimized to show excellent EU and CEC efficiency ratings. Two of the inverters featuring two inputs did not show an exceptional performance at the EU- and CEC-ratings, but they achieved top ranks at the AC energy yield for the first years. For the customer, the AC yield is a major performance indicator of any microinverter and should be included in the datasheet.","lang":"eng"}],"date_created":"2020-04-29T05:31:12Z","type":"conference","keyword":["yield","AC","micro-inverter","MPPT","CEC rating","EU efficiency","Photovoltaic","Solar"],"department":[{"_id":"53"}],"status":"public","conference":{"location":"VIRTUAL MEETING","name":"47th IEEE Photovoltaic Specialists Conference (PVSC 47)","start_date":"2020-06-15","end_date":"2020-08-21"},"page":"1429-1432","publisher":"IEEE","_id":"16899","user_id":"28836","citation":{"mla":"Krauter, Stefan, and Jörg Bendfeld. “Comparison of Microinverters: Update on Rankings of Conversion Efficiencies and Energy Yields.” <i>Proceedings of the 47th IEEE Photovoltaic Specialists Conference (PVSC 47) JUNE 15 - AUGUST 21, 2020 VIRTUAL MEETING</i>, IEEE, 2020, pp. 1429–32, doi:<a href=\"https://doi.org/10.1109/PVSC45281.2020.9300953\">10.1109/PVSC45281.2020.9300953</a>.","bibtex":"@inproceedings{Krauter_Bendfeld_2020, place={online}, title={Comparison of Microinverters: Update on Rankings of Conversion Efficiencies and Energy Yields}, DOI={<a href=\"https://doi.org/10.1109/PVSC45281.2020.9300953\">10.1109/PVSC45281.2020.9300953</a>}, booktitle={Proceedings of the 47th IEEE Photovoltaic Specialists Conference (PVSC 47) JUNE 15 - AUGUST 21, 2020 VIRTUAL MEETING}, publisher={IEEE}, author={Krauter, Stefan and Bendfeld, Jörg}, year={2020}, pages={1429–1432} }","ama":"Krauter S, Bendfeld J.

Im Rahmen des von uns im Jahr 2017 organisierten Symposiums zum Thema „Data Science“ wurden für die Bildung relevante Aspekte erörtert, wodurch als Kernelemente für den Unterricht Algorithmen der Künstlichen Intelligenz und ihre Anwendung in Industrie und Gesellschaft, Explorationen von Big Data sowie der Umgang mit eigenen Daten in sozialen Netzwerken herausgearbeitet wurden. Ziel ist, aus diesen Themenbereichen sowohl ein umfassendes Curriculum als auch Module für verschiedene Unterrichtsszenarien zu entwickeln und zu erproben. Durch diese Materialien soll es Lehrkräften aus der Informatik, Mathematik oder Technik ermöglicht werden, diese Themen auf Basis des Curriculums und der erprobten Unterrichtskonzepte selbst zu unterrichten.\r\nHierfür wurde im Rahmen des Projekts ProDaBi (Projekt Data Science und Big Data in der Schule, https://www.prodabi.de), initiiert von der Telekom Stiftung, ein experimenteller Projektkurs entwickelt, den wir mit Schüler:innen der Sekundarstufe II an der Universität Paderborn im Schuljahr 2018/19 durchführten. Dieser Kurs enthält neben einem Modul zur Exploration von Big Data und einem weiteren Modul zum Maschinellen Lernen als Teil der Künstlichen Intelligenz auch eine Projektphase, die es in Zusammenarbeit mit lokalen Unternehmen den Schüler:innen\r\nermöglicht, das Erlernte in ein reales Data Science-Projekt einzubringen. Aus den Erfahrungen dieses Projektkurses sowie den parallel durchgeführten Erprobungen einzelner Bausteine auch mit beruflichen Schulen werden ab dem Schuljahr 2019/20 die hierfür verwendeten Materialien weiterentwickelt und weiteren Kooperationspartnern zur Erprobung zur Verfügung gestellt. Damit wurden zum Ende des Projekts nicht nur vollständige Unterrichtsmaterialien, sondern auch ein umfassendes Curriculum entwickelt."},{"text":"The topics ”Big Data”, “Artificial Intelligence” and “Data Science” are controversially discussed among the general public, but they present new challenges for training in IT and IT-related professions. These challenges will become more important in the future as a result of further social and technological development towards a data society.\r\nAt this point, the question arises as to which aspects of this large complex of topics are important for school and education, and how these topics can be integrated in a meaningful and profitable way into informatics education in vocational education. In 2017, we organized a symposium towards the topic “Data Science” and discussed relevant aspects for general and vocational education. Algorithms of artificial intelligence and their application in industry and society, explorations of Big Data as well as the handling of one's own data in social networks were worked out as core elements for teaching. For this reason, our aim is to develop a comprehensive curriculum on this topic from these subject areas and to develop and test modules for various teaching scenarios in order to enable teachers from computer science, mathematics or technology to teach these topics themselves.\r\nFor this purpose, an experimental project course was developed within the framework of the ProDaBi project (Project Data Science and Big Data at School, https://www.prodabi.de), which we conducted with students from upper secondary classes at the University of Paderborn in the school year 2018/19. In this course we try to address all these aspects. This course consists of several modules: One module has been designed to teach the exploration of Big Data. Another module encompasses aspects of machine learning as part of artificial intelligence. The course concludes in a project phase which, in cooperation with local companies, will enable the students to apply what they have learned into a real Data Science project. Based on the experiences of this project course and the parallel testing of individual modules with vocational schools, we will further develop the material and make it available to other cooperation partners for testing, so that not only complete teaching materials but also a comprehensive curriculum will have been developed until the end of the project.","lang":"eng"}]},{"language":[{"iso":"eng"}],"date_updated":"2022-01-13T08:47:32Z","year":"2020","title":"Demystifying TasNet: A Dissecting Approach","author":[{"full_name":"Heitkaemper, Jens","last_name":"Heitkaemper","first_name":"Jens","id":"27643"},{"full_name":"Jakobeit, Darius","last_name":"Jakobeit","first_name":"Darius"},{"id":"40767","first_name":"Christoph","last_name":"Boeddeker","full_name":"Boeddeker, Christoph"},{"full_name":"Drude, Lukas","first_name":"Lukas","last_name":"Drude"},{"last_name":"Haeb-Umbach","first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold","id":"242"}],"keyword":["voice activity detection","speech activity detection","neural network","statistical speech processing"],"type":"conference","department":[{"_id":"54"}],"file":[{"date_created":"2020-12-11T12:36:37Z","creator":"jensheit","content_type":"application/pdf","success":1,"file_id":"20699","date_updated":"2020-12-11T12:36:37Z","relation":"main_file","file_size":3871374,"access_level":"closed","file_name":"ms.pdf"}],"date_created":"2020-11-25T14:56:53Z","abstract":[{"text":"In recent years time domain speech separation has excelled over frequency domain separation in single channel scenarios and noise-free environments. In this paper we dissect the gains of the time-domain audio separation network (TasNet) approach by gradually replacing components of an utterance-level permutation invariant training (u-PIT) based separation system in the frequency domain until the TasNet system is reached, thus blending components of frequency domain approaches with those of time domain approaches. Some of the intermediate variants achieve comparable signal-to-distortion ratio (SDR) gains to TasNet, but retain the advantage of frequency domain processing: compatibility with classic signal processing tools such as frequency-domain beamforming and the human interpretability of the masks. Furthermore, we show that the scale invariant signal-to-distortion ratio (si-SDR) criterion used as loss function in TasNet is related to a logarithmic mean square error criterion and that it is this criterion which contributes most reliable to the performance advantage of TasNet. Finally, we critically assess which gains in a noise-free single channel environment generalize to more realistic reverberant conditions.","lang":"eng"}],"publication":"ICASSP 2020 Virtual Barcelona Spain","ddc":["000"],"user_id":"40767","_id":"20504","has_accepted_license":"1","status":"public","quality_controlled":"1","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"file_date_updated":"2020-12-11T12:36:37Z","citation":{"bibtex":"@inproceedings{Heitkaemper_Jakobeit_Boeddeker_Drude_Haeb-Umbach_2020, title={Demystifying TasNet: A Dissecting Approach}, booktitle={ICASSP 2020 Virtual Barcelona Spain}, author={Heitkaemper, Jens and Jakobeit, Darius and Boeddeker, Christoph and Drude, Lukas and Haeb-Umbach, Reinhold}, year={2020} }","ama":"Heitkaemper J, Jakobeit D, Boeddeker C, Drude L, Haeb-Umbach R.
