“…Up to now, electric mobility has yet to be considered. Since literature such as Strobel et al (2022) clearly show that a large electric fleet significantly impacts peak load, especially on the local distribution level we are concerned with, the next step is integrating electric mobility into the digital twin. Moreover, advanced analysis will be performed to evaluate different control strategies for the battery storage system charging, especially those that include demand and PV production forecasting.…”

The steadily increasing usage of smart meters generates a valuable amount of high-resolution data about the individual energy consumption and production of local energy systems. Private households install more and more photovoltaic systems, battery storage and big consumers like heat pumps. Thus, our vision is to augment these collected smart meter time series of a complete system (e.g., a city, town or complex institutions like airports) with simulatively added previously named components. We, therefore, propose a novel digital twin of such an energy system based solely on a complete set of smart meter data including additional building data. Based on the additional geospatial data, the twin is intended to represent the addition of the abovementioned components as realistically as possible. Outputs of the twin can be used as a decision support for either system operators where to strengthen the system or for individual households where and how to install photovoltaic systems and batteries. Meanwhile, the first local energy system operators had such smart meter data of almost all residential consumers for several years. We acquire those of an exemplary operator and discuss a case study presenting some features of our digital twin and highlighting the value of the combination of smart meter and geospatial data.

“…In this study, we make a middle-ground assumption on the flexibility of electricity demand from BEVs. On the one hand, we assume charging to be flexible within limits and can adapt to supply which does not reflect current regulation in all European countries but neither requires additional infrastructure [46]. On the other hand, we do not assume that BEVs can feed electricity back to the grid, also termed bidirectional charging or vehicleto-grid, which requires bidirectional chargers [47].…”

To phase-out fossil fuels, energy systems must shift to renewable electricity as the main source of primary energy. In this paper, we analyze how electrification can support the integration of fluctuating renewables, like wind and PV, and mitigate the need for storage and thermal backup plants. Using a cost minimizing model for system planning, we find substantial benefits of electricity demand in heating, transport, and industry adapting to supply. In Germany, flexible demand halves the residual peak-load and the residual demand and reduces excess generation by 80%. Flexible operation of electrolyzers has the most significant impact accounting for 42% of the reduction in residual peak-load and 59% in residual demand. District heating networks and BEVs also provide substantial flexibility, while the contribution of space and process heating is negligible. The results are robust to restrictions on the expansion of the transmission grid.

“…This approach is a compromise regarding the flexibility of BEVs in future power systems which is still subject to significant uncertainty. On the one hand, we assume charging can be flexible to some degree and can adapt to supply [67]. On the other, we do not consider bidirectional loading, also known as vehicle-to-grid, where BEVs can operate like regular batteries and supply energy back to the grid [68].…”

Many governments consider the construction of new nuclear power plants to support the decarbonization of the energy system. On the one hand, dispatchable nuclear plants can complement fluctuating generation from wind and solar, but on the other hand, escalating construction costs and times raise economic concerns. Using a detailed energy planning model, our analysis finds that even if-despite the historic trend-overnight construction costs of nuclear half to 4,000 US-$ 2018 per kW and construction times remain below 10 years, the cost efficient share of nuclear power in European electricity generation is only around 10%. This analysis still omits social costs of nuclear power, such as the risk of accidents or waste management. To recover their investment costs, nuclear plants must operate inflexibly and at utilization rates close to 90%. As a result, grid infrastructure, flexible demand, and storage are more efficient options to integrate fluctuating wind and PV generation.
