Development of a Methodology for Identifying grid-serving Locations of Flexibilities in a sectoral-coupled Distribution Grid

Abstract:
The energy transition poses considerable challenges for distribution grid operators in Germany, as the grid infrastructure needs to be adapted to decentralised and volatile energy generation. To reliably achieve the system integration of renew-able energies in a sectoral-coupled distribution grid and thus the decarbonisation of the energy consumption sectors, measures are required that complement the traditional grid expansion. The integration of flexibility options into distribu-tion grids has been defined as one important measure to operate the grid infrastructure in a stable manner in the future and to meet the time requirements of the decarbonisation strategy in Germany. Grid operators now face the challenge of identifying locations for operators of battery storage systems, electrolysers, demand side management, Power-to-Heat technologies and so on to enable grid-friendly and grid-serving operation. This paper presents the methodology for a data-based assessment of the potential of grid-serving locations for flexibilities in distribution grids. In the second step, the focus is on determining the location for power-to-gas technologies in a sector-coupled distribution grid.
