What is the study about?
The future brings a strong increase in networked devices. Thanks to the increasing importance of the "Internet of Things", practically every area is affected. Switzerland's Energy Strategy 2050 presents another challenge. Among other things, this calls for lower energy consumption, more renewable energy sources and the phasing out of nuclear power. One of the consequences of implementing the energy strategy is that electrical energy is more volatile than we are used to today. One solution is the application of smart energy management.
One approach to smart energy management is that the detailed energy consumption of individual devices is known, and feedback and energy management systems are implemented on the basis of this information. The energy consumption of individual devices can be determined with sub-metering or load distribution algorithms. Here we investigate another approach: energy aware devices. Such devices know their own energy consumption and can communicate it to the outside world.
The purpose of the study is to assess the potential benefits of such energy aware IoT devices in smart energy management applications.
We have developed use cases and scenarios and described their benefits. Subsequently, we developed technical architectures for the integration of such devices and their connection to building or neighbourhood energy management systems. In order to achieve the full benefit of energy aware devices, we have expanded the concept of energy awareness: In addition to the current energy consumption, the devices should also provide a forecast of their energy consumption for the next few hours and receive control commands from outside. Such systems have the potential to support the energy system and reduce the volatility of renewable energy sources. However, the coordinated action of many devices is needed to achieve a significant effect.
