Fraunhofer ITWM

Open Source Smart Grid Solutions powered by Fraunhofer ITWM

Kaiserslautern/Munich (ots)

The Fraunhofer Institute for Industrial Mathematics provides flexible building blocks for energy information systems - ranging from smart metering components to PV self-consumption optimization combined with home automation systems. Most components are available under a liberal open source license and can easily be adopted to meet customer needs.

The Fraunhofer HexaBus is an IPv6-ready home automation system. It integrates seamlessly in existing home networks. This allows customers to configure and control electrical devices with any computer. The HexaBus is a wireless bus system optimized for reliable communication in buildings. It can be easily installed into customer households. Due to its easy self-installation, it is also attractive for rented apartments. The HexaBus components are available at a very attractive price.

The Fraunhofer self-consumption optimization increases significantly the consumption of locally generated PV energy, which is highly profitable in Germany. The optimization is based on a transparent energy balance, showing exactly the current consumption and PV energy generation, and individual PV energy yield forecasts. This allows users to adapt their consumption to match the local PV generation perfectly. Based on the energy yield forecasts, users get recommendations of when to use selected devices, e.g. a dishwasher, in order to increase their PV self-consumption. Users are able to assess their changed consumption patterns by intuitive charts and reports. In combination with the HexaBus, it is also possible to automatically control devices in line with the PV self-consumption optimization. Moreover, we provide PV monitoring services to detect and report malfunctioning PV components.

Fraunhofer mySmartGrid is an easy but powerful energy management platform. It provides smart metering and demand-side-management services. It is based on the Flukso Smart Metering solution to track power consumption, PV feed-in, and PV generation. In addition to the mySmartGrid website the Chumby home display also shows local power consumption/generation. The combination of technologies helps users to optimize their PV self-consumption and to reduce their total energy usage.

Most developments are published under a liberal open source license. Thus, it is possible to integrate the mySmartGrid platform into your solutions or to retrieve measured data out of the mySmartGrid. By joining an upcoming development consortium, it is possible to influence the platform development in order to address customer needs.
