This paper presents a literature review from previously conducted studies on potential benefits of cooperation in balancing services exchange. The brief overview and the main principles of the European mFRR platform are given. The main challenges and risks that play a role in the design of the ongoing mFRR platform development are identified and discussed, recommendations for further research are given.","PeriodicalId":192943,"journal":{"name":"2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115760364","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}

Secondly, the time Interval requirements for soft switching conditions are described, and the peculiarities of the studied algorithms are summarized. Finally, the algorithms are verified with a simulation model of a 1 kW converter incorporating thermal models of semiconductor switches.

According to the studies results, it is possible to achieve high CO reduction rates with relatively small increase of NOx concentration in flue gases. Despite the fact of a high number of the similar researches, experimental units involved conventional layout of the DC or AC source connection to the electrodes. In framework of the current research was proposed new DC source connection layout to the electrodes, which allowed to rise the electric field intensity to 1150kV/m keeping the maximum potential difference between electrodes at 2.3kV level. The maximum registered CO emissions reduction in application of electric field, which was produced internally in burner, achieved 41% comparing with electric field free conditions. In addition to emissions reduction, FFT analysis of acoustic signal showed significant amplitude rise at high electric field intensity levels.","PeriodicalId":192943,"journal":{"name":"2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131286160","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 paper describes the design of individual student’s educational trajectories based on an educational thesaurus. The offered method supports the overall set of concepts in the learner’s knowledge domain providing a suitable arrangement of study for different groups of learners.
