Against the backdrop of rising global demand for energy and the finite nature of fossil fuels such as oil and gas, the German government has set itself the goal of increasing the share of electricity from wind and sun in gross energy consumption from currently around 15 percent to 60 percent in 2050 as part of the energy transition. There is still a long way to go and it raises the question of how the future energy system should be designed under increasingly volatile energy production conditions.
Cross-sector planning of energy networks (i.e. integration of electricity, gas, district heating and mobility) offers the possibility of exploiting synergies between different energy sources and thereby making energy systems more cost-efficient and low-carbon, as well as guaranteeing the stability of the networks in the future. However, integrated planning also increases complexity, since many influencing factors with their interactions, different interests of the actors involved (i.e. utilities, network operators and policymakers) and uncertainties in the planning process must be considered.
Therefore, a decision support system is to be developed in this project which supports the mentioned actors in this planning and transformation process and provides recommendations for the future design of energy systems. In addition to recommendations on network design, recommendations on the design of new business and tariff models as well as regulatory policy recommendations are to be derived (see figure 1).
