This study aimed at keeping load variation under control by planning daytime load distribution using IoT-based energy measurement and central management software. By using IP-based smart meters and control methods to perform energy measurements, all loads on the microgrid can be loaded in a balanced manner from the centralized software. Moreover, load balance across the grid can be protected by shutting off the relevant overcurrent devices. By setting the load limits for certain zones at specific times of the day, both the electrical devices and the microgrid are safeguarded. In heating and cooling applications, when all components on the grid are overloading the microgrid, other electrical appliances are prevented from exceeding the permitted current limits. Thus, installation of the system results in energy saving and reduced costs. Details are shown in this study.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123171458","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 developed application utilizes microservices based architecture which improves code maintenance, enables easier scalability and improves the reliability of the system. The implemented application presents three services: DeviceHive connector, Database and Schedule service. Each of them uses its own instance of a database for storing service related data. This approach enables the performing of local control over the demand response without using cloud control logic. The application is built using mostly open source software modules.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121120738","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}

Possibilities for independent stepless control of the radiation's intensity in the different spectral areas are realized. The distribution of the irradiance in the processing field under different lamp operating modes is investigated. The appropriate thermal management ensures small thermal load on the LEDs with a passive cooling system. The realized lamp gives the opportunity to study the influence of the light flux's features on the development of different plants species and the determination of the optimal characteristics at low energy costs.","PeriodicalId":127983,"journal":{"name":"2017 XXVI International Scientific Conference Electronics (ET)","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134518476","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}
