Callia - EU-funded project about transnational integration of Renewable Energies into the European power grid
BlueSky Energy brings in to the Callia project it’s expertise and know how in electrical energy storage. Safe and environmentally friendly saltwater batteries are installed for back-up at the Stadtwerke Heidelberg. Further back-up installations are planned in Turkey. The project was started in 2016 and is now in its final year. Companies and research institutions from Germany, Belgium, Austria and Turky are working on the project.
Europe’s ambitious energy goals require a safe and comprehensive integration of Renewable Energies on all voltage levels of the electricity grid. Currently, cross-border transmission of electricity is limited to the high voltage grid. Within CALLIA, the partners will investigate how direct energy transfer between distribution grids in two different countries is able to foster the integration of Renewable Energies. Important goals of the project are more efficient integration of decentralized generation units and stabilization of the European electricity grid. Therefore, grid operators, research institutes and industrial partners from Austria, Belgium, Germany and Turkey join forces in a multilateral project consortium coordinated by ISC Konstanz.
Project Summary
Open inter‐DSO electricity markets for RES Integration: open electricity markets for direct interaction between grids including renewable energies.
Main objective is an over-all integration of renewable energy into the european electricity grid.
- Efficient integration of decentralized powers
- Network stabilisation
- Cross-border power transmission
Bringing together what belongs together
Within CALLIA, project partners investigate how cooperation between distribution service operators can be put into practice. The necessary architecture as well as an interface for trading between distribution service operators (so-called “multi-agent system”) will be developed.
Local exchange of Renewable Energies at the distribution grid level will reduce the curtailment of RE systems, reduce the load at the transfer points between distribution and transmission grid and simplify balancing between local distribution grids and the transmission grid.
Furthermore, energy losses will be reduced as local generation and local consumption in border regions can be balanced more easily without the need to cross all voltage levels in an “up-across-down” trajectory (up from low-voltage to high voltage grid – across to the neighboring high voltage grid and down to the receiver’s low voltage grid).
After all, the project will lead to a more efficient integration of decentralized generation into Europe’s electricity grids accompanied by an increase in stability. Project results will both be validated through simulations and through a pilot of the trading interface for grid operators. Based on the knowledge obtained, recommendations for a regulatory framework for electricity exchange between distribution grids on the European level will be given.
