There are two fundamental ideas which substantiate this invention: 1) enhancement of the efficiency of separate system elements, improvement of system algorithms, as a result more rational use of Earth resources and energy sources; 2) improvement of the environment for human habitation. Majority part of these studies consider term \"smart\" as the ability of the system to provide the necessary amount of the light in accordance with the existing norms, lighting standards when it is necessary and where it is necessary. In other words, the system is considered \"smart\" from point of view of the main end users: drivers, cyclists and pedestrians, in the same time forgetting about system service staff: installation technicians and system administrators. This paper endorse studies of smart lighting systems in this extended meaning: considering system \"smart\" for all the system users. Therefore some low cost solutions with extended functionality are considered in this paper.","PeriodicalId":192943,"journal":{"name":"2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"27 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":"123419184","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}

By adding a special power electronic interface (PEI) to the point of common coupling, the conventional NZEB could be transformed into a hybrid nanogrid with a wider variety of functions, incl. off-grid operation and bidirectional energy flow control. However, most of the sources in the NZEB are grid followers and require a single grid-forming unit. Thus, typical decentralized control methods (e.g. droop control, virtual generator) cannot be implemented in such systems. This paper analyzes the bidirectional operation of the grid-forming inverter for the NZEB. The main focus is on the light or no load operation that corresponds to a mode when the PEI is naturally unable to control the voltage inside the building. Four control methods are proposed, analyzed and compared. The best method was determined and verified by the help of computer simulations.","PeriodicalId":192943,"journal":{"name":"2018 IEEE 59th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"32 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":"125759844","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}
