Efficient PV system monitoring with current weather data
Test and improvement of the monitoring system of EGON AG. The system calculates based on the latest weather information, the target production of a system and compares it to the actual production. This loss of production (for example caused by string failure)
Electrical energy is generated increasingly decentralized with intermittent sources and the consumer is becoming a prosumer, because he often also produces electrical energy. To balance supply and demand, utilities will influence energy usage patterns with time dependent tariffs. Thus the prosumer has to decide, whether to sell, buy, consume or store energy. To support this process a brokerage system will be explored, which leverages the smart grid infrastructure.

Energy Efficiency in IoT
Invistigation for the Interational Energy Agency (IEA) about the energy consumption of networked devices within the "Internet of Things"
REALYSE will show the full potential of the so called NIALM technology (Non Intrusive Appliance Load Monitoring).
The measured values - the fingerprint - will be used to benchmark the appliance with the best in class products. A benchmark portal like TopTen.ch will be interfaced to give a hint, which product will serve the needs the most efficient way.
Keywords: NIALM, Energy Efficiency, End Devices, Benchmark
"Demand-Response" researches smart concepts with BKW, Siemens, swissgrid and MeteoSchweiz so that energy suppliers and consumers can adapt and be ready for the energy market of the future.
NEUTUN researches a method for the accurate assessment of the residual life of these network components using low-cost devices.
In this research project, current and voltage analysis will be used to determine the residual life. To date, a cost-effective method and equipment for assessing the condition of network components are missing.

SEM - Smart Energy Monitor
The Smart Energy Monitor is a system that measures the power consumption of connected electrical devices live and in real time, visualizes it and makes suggestions for improvement. The presentation is intuitively understandable for everyone, so that all have an incentive to consume as little electricity as possible.
The "Smart Energy Monitor" is the result of a research project on iHomeLab, which was co-financed by the Swiss Federal Office of Energy.

Efficiency study for the International Energy Agency "IEA" on the topics of "NIALM" and "Smart Metering Consumption".
The intelligent powersocket "iKnowWatt" which has been developed together with the Federal Office of Energy, Landis + Gyr, BKW, ewz Feller and Swisscom recognizes the electrical devices connected to it and measures their power consumption. The energy consumption is visualized on a standard display (iPhone, tablet, etc.) and gives tips on saving electricity.
This makes it possible to compare the power consumption of the devices an repalce the ones which are not energy efficient. Users can control their own energy consumption and learn how to improve it. In Swiss households, up to 15 percent of electrical energy could be saved, just by visualization.
Keywords: energy visualization, IoT, Internet of Things, NIALM
Studies are showing that systems, which give the occupants a detailed feedback on their energy usage, result in an average energy saving of 5 to 15%. LoReMA helps, to utilize this potential. Its goal is, to measure every single appliance in the household and to display their energy consumption in real time. The energy is measured directly inside the power socket and transmitted to the display by means of a low power ZigBee radio link.
