Approach

In a first step, current consumer final energy demands as well as future projections and detailed data of the current grid infrastructure are gathered. Different transformation paths for the household, transportation and industry sectors will be designed. A methodology allowing, based on simulation results, to compare (using different parameters) multiple grid expansion alternatives will be developed. For different scenarios, a classification into zones of comparable demand structures is to be created. A novel, aggregated model, taking into account all physical boundary conditions, will form the basis for the planning of integrated grid. The combined result of applying both the method and model will allow for the derivation of grid expansion recommendations. Towards this, a computer-aided process, including AI support, will be developed. The resulting method as well as planning processes and tools will be usable as a template for other industrial metropolises.

Tasks

• Selection of sector coupling technologies to be regarded
• Sector-spanning grid computations
• Analysis of grid computation methods of separate energy grids
• Identification of sector-spanning planning goals
• Development of a grid planning method for integrated grids under consideration of possible goals
• Software implementation of the method and integration with existing software
• Knowledge exchange with other working groups within the Northern German Living Lab

Relation to the Northern German Living Lab parent project

Other than primary coupling stations, sector coupling also requires suitable transmission and distribution infrastructure in the form of energy grids. Without these, a connection of energy producers, consumers and coupling stations is not economically feasible. The grids need to fit demand, as this is the only way grid congestion, leading to decreased quality of supply for grid users, is avoidable. Grid expansion has to take place in a sector-coupled and integrated way, enabling comprehensive and efficient operation of sector-coupling technologies as well as forming economic incentives for the development of new value chains, like a regional hydrogen economy. The developed roadmap will be able to highlight options for grid and sector coupling expansions and thus contribute towards the decarbonization goal of reducing CO₂ emissions by 75 percent until 2035. The implementation and translation of the roadmap into operative planning leads to a transformation of the energy grids.
