Future quarter 2.0 - Replicable, thermally and electrically grid-supportive conception of (positive energy) districts in a dense urban context
Starting point / motivation
A large proportion of renewable energy sources, often generated in a volatile way, places high demands on integration and security of supply of the entire energy. Trends towards a high level of on-site generation (keyword positive energy districts) should be realised without additional peak loads from feed-in peaks (PV) or simultaneous consumption (e-cars, peak in heating consumption).
Contents and goals
In dense urban areas, on the one hand demand side management and storage can help to solve these problems by adjusting local energy feed-ins and consumption to volatile on-site generation. On the other hand, energy storages in the district can bring increased flexibility to the energy grid.
District heating networks have enormous potential in this respect, since the aforementioned approach is still relatively unknown in the arena of district heating and because there is an evident need to optimize networks in order to sustainably ensure new connections to the grid in the future. But integrated energy systems also provide new flexibility to the electricity grid.
The project aims to develop a concept for incorporating innovative (positive energy) districts with a high level of on-site energy generation into the existing transmission grid infrastructure (electricity and district heating grid) in a grid-supportive manner. This will create a 'win-win' situation for suppliers and grid operators, as well as for consumers, investors and developers.
Moreover, comprehensive analyses concerning technical, economical, legal and social issues will be conducted in an integrated way. The project's innovative content is the development of a scientific method for optimal system design including storage technologies as well as the development of a local control strategy to enable interaction with the entire network.
In this way the district's envisaged daily, weekly and seasonal storages could react in a flexible, cross-sectoral manner to the needs of the grid and prevent or reduce power peaks. The envisaged HVAC concept will be subject to a sociological acceptance assessment and will result in several user-friendly, practicable load shifting measures. Life cycle based cost optimizations supported by suitable business and operator models complement the analysis.
Another innovative element of the project is the involvement of a real-life positive energy district in the Vienna district of Floridsdorf (Pilzgasse) and the intended consultation with other possible positive energy districts and relevant stakeholders throughout the project. This should result in clear conclusions regarding the need for adaptation during the planning stage.
Intensive collaboration between scientists and property developers (or their planners) should lead to findings that are robust and applicable in real life. The findings and solutions from "Zukunftsquartier 2.0" will be developed into instruction manuals and instruments of planning and process support for further district developments so the project can have a broad impact.
These widely applicable technical, economic and methodological findings about how to plan (positive energy) districts in a grid-supportive way will be disseminated among relevant target groups (planners, property developers, cities) via targeted activities.
