ECS4DRES is a groundbreaking EU project co-funded by Horizon Europe and the German Federal Ministry for Economic Affairs and Climate Action. The project, which runs from July 2024 to June 2027, brings together partners from Germany, Italy, Netherlands, Spain, and Slovakia to develop innovative solutions for managing low-voltage electrical grids, enhancing flexibility, resilience, and coordination of renewable energy systems.
The aim of the project is to enable the optimal utilisation of electrical low-voltage distribution grids. To this end, controllable electrical loads (electrically powered heat pumps, electric charging stations, electrolysers) are to be optimally coordinated with each other. Physical limits to the load capacity of the grid (transformer utilisation, node voltages, line utilisation) are taken into account. Requirements for the electrical loads described are also taken into account:
- Each heat pump must be able to cover its given thermal demand at all times.
- The desired requirements for charging processes of electric vehicles (desired charge level after charging and the desired time when the charging process should be completed) should be taken into account. If this is not possible due to the utilisation of the grid, "fair" charging should be guaranteed so that no one is discriminated against.
- Electrolysers should provide demand response in order to utilise local surpluses from fluctuating renewables such as photovoltaics directly on site.
The data required for the optimisation described above is recorded by smart meters and communicated between them. This communication is to take place via 5G and in a decentralised manner, thus avoiding a single point of failure.
The topology and status of the low-voltage grid can be reconstructed on the basis of the recorded data. Based on this, the described controllable loads can then be optimally coordinated.
To this end, appropriate algorithms are being developed and the necessary hardware purchased and integrated into a laboratory environment. Once the algorithms have been successfully tested in a simulation environment, they will be tested on a laboratory scale. Finally, the solutions developed will also be tested in a real low-voltage distribution network.
