Internet of Things (IoT) revolution seems a promising technology to create new tools and options to decrease electrical energy consumption in buildings of any type. It is planned to publish series of articles dealing both with electrical and heat energy multi-point measurements and consumption reduction options. This is first article, showing current studies, obtained findings and first results, focusing...
Paper is presenting application of synchronized power flow measurement system within 13 locations of DC microgrid installation in production plant with specific measurement equipment system developed for dynamic energy flow analysis. Insight into internal DC bus power exchange behavior and interconnected operation advantages with respect to energy efficiency improvement is provided. Future trends...
Paper deals with existing and future LED lighting control system architectures for Smart Grids and introduces to context aware intelligent LED lighting control system. Scope of this paper is limited to context awareness integration into management components, using networked control systems to identify particular context awareness applications in order to improve utilization efficiency, and minimise...
Bidirectional energy flow monitoring near 230 V AC or 600 V DC micro-grid consumers — industrial devices or household consumers — rise questions regarding measurement methods and devices self power consumption, price and precision. Article deals with overall 3×230V+N AC and 600V DC micro-grid bidirectional monitoring system design as well as measurement modules communication and data logging.
The article gives an overview of various researches dealing with smart or intelligent street lighting systems, and what is meant with this term in different countries. Several available architectures of smart street lighting systems as well as those for future are described and discussed. Further some researches and developments of such systems in Riga Technical University are explained with the examples,...
A different approach to electrical energy/power calculation by means of summing of non-even time current samples over short time periods are described in to the article.
Due to continuous development of office and household equipment, the electricity end-consumer profile has changed in latest years, and increasing number of electricity consuming equipment, makes very hard to identify real electricity consumption of each device. Long-term power consumption monitoring with existing wall plug digital power meters can be an expensive method for consumers with large number...
