Wind energy plays a key role in ensuring a sustainable and resilient energy supply, as well as in the decarbonisation of the energy system. However, as the expansion of renewable energy sources continues, new issues are coming to the fore: in particular, the flexible grid integration of wind turbines and the strengthening of system resilience are becoming increasingly important.
The integration of large, partly decentralised generation units places new demands on grid infrastructure, operational management and system stability. At the same time, innovative concepts – such as hybrid systems, storage solutions or smart grid control – open up new opportunities to increase flexibility and ensure security of supply even under dynamic conditions.
How can the grid integration of wind energy be made more flexible and efficient? Which approaches help to increase the resilience of energy systems? And which technical and regulatory frameworks are crucial for successful implementation in practice?

>Project Profile

 

Municipal utility München’s district cooling network comprises its own supply network, approximately 25 kilometres in length, and currently supplies cooling to around 120 large buildings in Munich city centre. As a hybrid district cooling system, cooling is generated partly using natural cooling (the western city moat) in conjunction with underground ice storage tanks (170,000-litre capacity). In addition to conventional chillers, absorption chillers are also used, which utilise waste heat from combined heat and power (CHP) and geothermal energy. Alongside the city centre district cooling network, Stadtwerke München operates eight innovative groundwater cooling/heating networks, which will also be presented during the excursion.

The low-temperature district heating network in Meitingen, with a total length of 1,100 metres, utilises industrial waste heat, which is supplied year-round at 30°C from the cooling circuit of the nearby SGL Carbon GmbH. The nearly 300 residential units in the new-build development supplied with heat are equipped with decentralised heat pumps and small buffer tanks. In addition, a central buffer tank with a capacity of 15,000 litres has been installed. An intelligent energy management system for real-time control integrates the PV electricity generated by a 99 kWp system, enabling around one third of the heat pumps’ electricity requirements to be met from renewable sources.

The share of renewable energy has risen steadily in recent years – a development that is a key building block for the heating transition and a sustainable future. Solar thermal systems offer a way to decarbonise heating networks, thereby replacing fossil fuels.
As part of the ‘Heat Pump & District Heating Network – Shaping the Heat Transition Intelligently’ transfer cluster, we, together with our network partner Naturstrom AG, invite you to join us on an excursion to Marktschorgast and Hallerndorf.

In Marktschorgast, Naturstrom and InES installed the world’s first insulated-glass collector field in 2023 (see the flexLAC research project). This district heating network represents a high-performance combination of biomass, gas boilers and solar thermal energy.
The plant in Hallerndorf supplies the region with 100 per cent renewable energy (around 3 million kWh of heat) through its intelligent combination of biomass and ground-mounted solar thermal energy systems.

Tour of the solar thermal-supported district heating network 1:
combi boiler (fuelled by pellets or wood chips), CHP unit (base load) and gas boiler (redundancy) in conjunction with roof-mounted solar thermal energy systems (270 m²) and ground-mounted solar thermal energy systems (125 m² as a double-glazed collector array) in Marktschorgast.

How does the heating and cooling system work at the Audi Sportpark? Participants on the field trip gained interesting insights into this from the municipal utility Ingolstadt (SWI) and Audi Immobilien Solutions GmbH.

On 15 October 24, 45 participants, including specialists and managers from relevant sectors, decision-makers from business and academia, and interested students, had the opportunity to take part in an exciting, practical excursion organised by the Institute of new Energy Systems (InES) at Ingolstadt University of Technology.

At the end of 2018, a pioneering energy concept involving ‘cold district heating’ was implemented in the new-build development on Afrastraße in Friedberg. This enables more than 200 residential units to be supplied with heat and hot water in a particularly energy-efficient and climate-friendly manner. The project was presented to participants during a field trip in July 2019.

The power-to-gas plant operated by the municipal utility in Haßfurt – a 1.25 MW electrolyser – produces green hydrogen from surplus electricity generated by the nearby wind farm and local solar installations. Some of this hydrogen is fed into the town’s natural gas network, supplies the combined heat and power plants at the neighbouring malting plant, or is converted back into electricity and heat in the hydrogen-fuelled combined heat and power plant.

The district heating network in Eltmann, which has already taken part in a grid repowering project (see the OREWA project), is to be extended via a second feed-in point to supply a large school complex on the opposite edge of the town. We intend to visit the site and discuss with those responsible how this can be achieved in a cost-effective and energy-efficient manner.

It has been clear for some time, even before the debate surrounding the Heat Planning Act, that district heating is a key component of the future heat supply. However, particularly in the case of existing heating networks – which were established thanks to funding under the EEG – questions arise such as:

When is it worthwhile to retrofit decentralised and/or central buffer storage tanks?
Does it make sense to upgrade the building terminals?
We will address these and other questions at the final workshop for the research project “OREWA – Development of a catalogue of measures for the optimisation and restructuring of heating networks, including an assessment of transferability, environmental impact and economic viability”. We will also be presenting specific planning tools for implementing optimisation measures in existing heating networks – which have been developed and formulated specifically for non-engineers.

The project was carried out in collaboration with Enerpipe and funded by theFederal Ministry for Economic Affairs and Climate Action (BMWK).

As part of our concluding workshop ‘How can existing district heating networks be made fit for the future?’, we at theInstitute of new Energy Systems would like to outline future prospects for you and, in a workshop setting, clarify questions and share knowledge together.

District heating networks are a key driver of the energy transition and of achieving climate targets relating to the heating sector and, in particular, the buildings sector. A variable temperature level is a forward-looking component for the optimal integration of renewable energies and waste heat: This enables heat network losses to be reduced and sustainable local heating systems to be created. How must these technologies evolve to ensure the most efficient and renewable heat supply possible? The innovation cluster “Rural Energy Supply of the Future” (LEnZ) addressed this topic during the workshop.

From 2026 onwards, the Building Energy Act (GEG) will strictly regulate the installation of oil-fired heating systems, which will only be permitted in exceptional cases. Wherever possible, individuals, businesses and local authorities are already being asked to opt for a climate-friendly heating solution. As gas and district heating are not available at all in rural areas, the heating transition in the countryside is being driven primarily by local heating schemes and heat pumps, alongside individual solar thermal systems and wood-fired heating options. The key question, therefore, is: what will replace oil heating? How do these technologies need to evolve to ensure a 100 per cent renewable heat supply? The innovation cluster “Rural Energy Supply of the Future” (LEnZ) addressed this topic during the symposium.

At the start of 2019, two district heating storage tanks came into operation on the premises of the municipal utility Ingolstadt (SWI). The two 25-metre-high storage towers each have a capacity of 1,600 m³ and can store a total energy volume of around 170 MWh. All information relating to the control and monitoring of the distribution networks for district heating – as well as electricity, gas and water – is centralised at SWI’s integrated control centre. This project was presented to participants during a field trip in November 2019.
