Abstract: Optimization of Urban Energy Supply Systems Considering an Increasing Integration of Battery Electric VehiclesIn Europe, the buildings sector accounts for 40% and cities for 69% of final energy consumption. The share of CO2 emissions in cities and urban districts are correspondingly high. To achieve the climate protection goals in Europe, new energy supply strategies must be sought for urban districts, which will not only make it possible to reduce CO2 emissions, but will also keep the costs of energy supply stable and guarantee security of supply.The special nature of urban districts is the limited potential for the installation of generation units on the one hand and the high population density with an accompanying high demand for energy on the other. Photovoltaics (PV) for electricity production, solar thermal and geothermal energy for heat generation are the most suitable renewable energy (RE) technologies in urban areas. However, a largely self-sufficient power and heat supply based on RE is difficult to implement in urban districts with limited RE potential. Furthermore, it should be noted that sector coupling options such as power-to-heat or electric vehicles will lead to an increasing demand for electricity in urban district in the future. The implementation of microgrids is a possible strategy for more efficient use of resources and greater integration of decentralized power generation and electric mobility. This paper analyses different scenarios with different penetration rates of electric vehicles and the resulting effects on energy demand, structure of power generation and transmission as well as energy system costs of a specific urban district in Germany. The analysis based on a mixed-integer linear programming approach, which determines an optimal technology configuration for a specific urban district and additionally optimizes the operation of generation technologies, storage technologies and energy transmission between the buildings. The total annual discounted energy system costs are calculated in a time resolution of one hour and in a spatial resolution of 18 building nodes. The energy system costs consist of fixed and capacity dependent investment costs and fixed and variable operating costs of the installed technologies. The demand for heat and electricity in the buildings is determined by using a bottom-up model approach. Furthermore, traffic demand profiles for the urban district are synthesized and the additional local power consumption for charging the electric vehicles is determined with different penetration rates. |
