The goal of I-GReta is to develop solutions for planning and operation of highly flexible energy systems benefitting from storage capacities. These will be capable of integrating high shares of renewables in regional and local energy networks through integrated demand flexibility and forecasting on building level as well as large-scale optimization-based control of electrical, heating, and cooling consumption. To achieve this goal, several demonstration projects will be carried out in Austria, Germany and Sweden.
A key innovation of the Swedish demonstration at HLL is the human-centred approach and the consideration of the needs of both system operators and building occupants, building managers and the public. Occupants and system operators will be able to influence the buildings’ automation systems via human-machine-interfaces (HMI) designed with a focus on user experience; we will develop a web application that can run on different devices. The preferences of end-users with regards to thermal comfort, energy savings and CO2 savings are considered. Behavioural strategies such as nudging and gamification are integrated to support active participation of end-users.
The consortium intends to build a real-world digitalized and decentralized energy system. At HLL, the partaking I-Greta partners will connect solutions from two earlier project at HSB LL namely, an
“innovative building energy management system (BEMS)”, and the “energy organizer application (ERO)” to achieve a crossdisiplinary approch on energy research where technical aspects of energy
flexibility is merged with user behavioural research. In the project, different energy actors in the building are connected via a professional ICT platform benefitting from FIWARE components. As key need owners, occupants will participate, and system operators (represented by the researchers) will assess the operation of the respective systems in a Virtual Smart Grid (VSG) based on the platform. A focus area will be the trading of storage capacities via the platform, and another one
the share of renewables in the system. To further study the included storage solutions will additionally provide extra value and impact potential in the local perspective.
