In order to achieve the national climate protection goals by 2050, a substantial share of energy in the electricity, heat and transport sectors will have to be provided from renewable energy sources in the future. The associated expansion of renewables will lead to a high proportion of decentralized, intermittent generation in the system. This ongoing trend is not only accompanied by new requirements for the interaction of conventional and renewable generation in the electricity sector, but will also be a major long-term driver for increasing interaction between the electricity, heating and transport sectors. The aim of the research project “GreenVEgaS” is the development of a multi-stage optimization procedure for the economic evaluation of cross-sectoral energy infrastructure, generation and demand. For this purpose, the application-specific optimization models of the project partners will be further developed and interlinked in order to be able to map the entire energy system in an iterative cross-sectoral overall model. Within this framework, various future scenarios are being examined with regard to their impact on the electricity, gas and heating sectors. The ie³ Research Group Energy System Design & Transmission Grids conducts electricity market simulations for the future scenarios and examines the effects on the transmission grid. The Research Group Distribution Grid Planning & Operation examines the effects on the distribution network infrastructure and determines the need for expansion in the distribution network, taking into account the flexibility available. In order to determine the optimal transformation path, inefficiencies in each sector are identified and future scenarios are improved. In this way, the aim, to describe optimal transformation paths towards an environmentally friendly, reliable and affordable energy supply, taking into account local and transregional boundary conditions of the network infrastructures for electricity, gas and heat can, be achieved.
