Sustainability’s Coming Home: Preliminary Design Principles for the Sustainable Smart District

Consumer trends like local consumption, sharing of property, and environmental awareness change our habits and thereby our surroundings. These trends have their origin in our direct environment, in the districts of our city or community, where we live and socialize. Cities and districts are changing to “smart cities” and “smart districts” as a part of the ongoing digitalization. These changes offer the possibility to entrench the idea of sustainability and build a platform-based ecosystem for a sustainable smart district. This research aims to identify guidelines in form of preliminary design principles for sustainable smart districts. To achieve this, we conduct a structured literature review. On this basis, we derive and develop preliminary design principles with the help of semistructured interviews and a non-representative sample of the German population. The resulting nine preliminary design principles describe a first insight into the design of sustainable smart districts

The Design of Citizen-Centric Green IS in Sustainable Smart Districts

Green information systems are often praised for their potential to foster sustainability in citizens’ daily lives and meet their needs. With this focus on citizens, districts that use smart technologies provide a litmus test, the results of which will indicate how to design smart green information systems that better meet the needs and desires of citizens. To date, however, guidelines on how to design such green information systems in urban areas or actively involve citizens in this process are few and far between. In recognition and remedy of this shortage, the study draws on the design science research paradigm to develop seven design principles for citizen-centric green information systems that can be used in sustainable smart districts. These principles are evaluated in 15 semi-structured interviews and a prototype of a mobile district app for a citizen-centric green information system is instantiated. By taking this citizen-centric perspective, the paper fosters the active involvement of humans in the design of sustainable urban environments

Cities and districts are changing to “smart cities” and “smart districts” as a part of the ongoing digitalization. These changes offer the possibility to entrench the idea of sustainability and build a platform-based ecosystem for a sustainable smart district. This research aims to identify guidelines in form of preliminary design principles (PDPs) for sustainable smart districts. To achieve this, we conduct a structured literature review. On this basis, we derive and develop PDPs with the help of semi-structured interviews and a non-representative sample of the German population. The resulting nine PDPs describe a first insight into the design of sustainable smart districts

Static and dynamic 68Ga-FAPI PET/CT for the detection of malignant transformation of intraductal papillary mucinous neoplasia of the pancreas.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) may arise from intraductal papillary-mucinous neoplasms (IPMN) with malignant transformation, but a significant portion of IPMN remains to show benign behavior. Therefore, it is important to differentiate between benign IPMN and IPMN lesions undergoing malignant transformation. However, non-operative differentiation by ultrasound, CT, MRI and carbohydrate antigen 19-9 (CA19-9) is still unsatisfactory. Here, we assessed the clinical feasibility of additional assessment of malignancy by positron emission tomography using 68Gallium-labeled Fibroblast Activation Protein Inhibitors (68Ga-FAPI-PET) in 25 patients with magnetic resonance imaging (MRI) - or computed tomography (CT) - proven cystic pancreatic lesions. Methods: 25 patients with cystic pancreatic lesions who were followed up in the European Pancreas Center of Heidelberg University hospital and who were led to surgical resection or fine needle aspiration (FNA) due to suspicious clinical, laboratory chemistry or radiological findings were examined by static (all patients) and dynamic (20 patients) 68Ga-FAPI-PET. Cystic pancreatic lesions were delineated and maximum and mean standardized uptake values (SUVmax / SUVmean) were determined. Time activity curves and dynamic parameters (time to peak, K1, k2, K3, k4) were extracted from dynamic PET data. Receiver operating curves (ROC) of static and dynamic PET parameters were calculated. Results: 11 of the patients suffered from menacing IPMN (high grade IPMN with (6 cases) or without (5 cases) progression into PDAC) and 11 from low grade IPMN, 3 patients from other benign entities. Menacing IMPN showed significantly elevated 68Ga-FAPI uptake compared to low grade IPMN and other benign cystic lesions. In dynamic imaging, menacing IPMN showed increasing time activity curves (TAC) followed by slow decrease afterwards, TAC of low grade IPMN showed an immediate peak followed by rapid decrease for about 10 minutes and slower decrease for the rest of the time. ROC curves showed high sensitivity and specificity (area under the curve (AUC) greater than 80%) of static and dynamic PET parameters for the differentiation of IPMN subtypes. Conclusion: 68Ga-FAPI-PET is a helpful new tool for the differentiation of menacing and low grade IPMN and shows the potential to avoid unnecessary surgery for non-malignant pancreatic IPMN

Electricity Market Design 2030-2050: Moving Towards Implementation

Climate change and ambitious emission-reduction targets call for an extensive decarbonization of electricity systems, with increasing levels of Renewable Energy Sources (RES) and demand flexibility to balance the variable and intermittent electricity supply. A successful energy transition will lead to an economically and ecologically sustainable future with an affordable, reliable, and carbon-neutral supply of electricity. In order to achieve these objectives, a consistent and enabling market design is required. The Kopernikus Project SynErgie investigates how demand flexibility of the German industry can be leveraged and how a future-proof electricity market design should be organized, with more than 80 project partners from academia, industry, governmental and non-governmental organizations, energy suppliers, and network operators. In our SynErgie Whitepaper Electricity Spot Market Design 2030-2050 [1], we argued for a transition towards Locational Marginal Prices (LMPs) (aka. nodal prices) in Germany in a single step as a core element of a sustainable German energy policy. We motivated a well-designed transition towards LMPs, discussed various challenges, and provided a new perspective on electricity market design in terms of technological opportunities, bid languages, and strategic implications. This second SynErgie Whitepaper Electricity Market Design 2030-2050: Moving Towards Implementation aims at further concretizing the future German market design and provides first guidelines for an implementation of LMPs in Germany. Numerical studies –while not being free of abstractions –give evidence that LMPs generate efficient locational price signals and contribute to manage the complex coordination challenge in (long-term) electricity markets, ultimately reducing price differences between nodes. Spot and derivatives markets require adjustments in order to enable an efficient dispatch and price discovery, while maintaining high liquidity and low transaction costs. Moreover, a successful LMP implementation requires an integration into European market coupling and appropriate interfaces for distribution grids as well as sector coupling. Strategic implications with regard to long-term investments need to be considered, along with mechanisms to support RES investments. As a facilitator for an LMP system, digital technologies should be considered jointly with the market design transition under an enabling regulatory framework. Additional policies can address distributional effects of an LMP system and further prevent market power abuse. Overall, we argue for a well-designed electricity spot market with LMPs, composed of various auctions at different time frames, delivering an efficient market clearing, considering grid constraints, co-optimizing ancillary services, and providing locational prices according to a carefully designed pricing scheme. The spot market is tightly integrated with liquid and accessible derivatives markets, embedded into European market coupling mechanisms, and allows for functional interfaces to distribution systems and other energy sectors. Long-term resource adequacy is ensured and existing RES policies transition properly to the new market design. Mechanisms to mitigate market power and distributional effects are in place and the market design leverages the potential of modern information technologies. Arapid expansion of wind andsolar capacity will be needed to decarbonize the integrated energy system but will most likely also increase the scarcity of the infrastructure. Therefore, an efficient use of the resource "grid" will be a key factor of a successful energy transition. The implementation of an LMPs system of prices with finer space and time granularity promises many upsides and can be a cornerstone for a futureproof electricity system, economic competitiveness, and a decarbonized economy and society. Among the upsides, demand response (and other market participants with opportunity costs) can be efficiently and coherently incentivized to address network constraints, a task zonal systems with redispatch fail at. The transition to LMPs requires a thorough consideration of all the details and specifications involved in the new market design. With this whitepaper, we provide relevant perspectives and first practical guidelines for this crucial milestone of the energy transition

Electricity Market Design 2030-2050: Shaping Future Electricity Markets for a Climate-Neutral Europe

Speeding up the energy transition in the European Union (EU) is a major task to quickly reduce harmful greenhouse gas emissions. Market design plays a crucial role in the decarbonization of the European energy system, driving the expansion of both Renewable Energy Sources (RES) and accompanying flexibility sources. In particular, demand flexibility by energy-intensive industrial companies can play a key role. By flexibilizing their production processes, industrial companies can contribute to an increased use of variable RES (in the following referred to as Variable Renewable Energy (VRE)) to lower the CO2 footprint of their products with positive effects on economic competitiveness. Together with other flexibility sources like electric vehicles, the EU can transition to a just, low-carbon society and economy with benefits for all. However, to actually realize these benefits, market design must account for the changing production and consumption characteristics, e.g., the intermittency of VRE. Starting with current challenges of the energy transition that need to be solved with a future market designin the EU, the whitepaper takes alternative market design options and recent technological developments into account, which are highly intertwined. The whitepaper elaborates on the role of, for instance, flexibility, digital technologies, market design with locational incentives, and possible transition pathways in a European context. The “Clean energy for all Europeans” package offers a new opportunity to deepen the integration of different national electricity systems, whereby Transmission System Operators (TSOs) are required to reserve at least 70% of transmission capacities for cross-border trades from 2025 onwards. The corresponding scarcity of transmission capacities on the national level, however, may aggravate congestion to a critical extent, calling for transformational changes in market design involving, e.g., a redefinition of bidding zones close to the network-node level. The present whitepaper can be seen as part of a series of whitepapers on electricity market design 2030 - 2050 [14, 15] and continues the analysis of regionally differentiated prices or Locational Marginal Pricing (LMP) as a means to address congestion problems in future VRE-based electricity systems. Thereby, the whitepaper extends the findings of the previous two whitepapers (where in the latter whitepapers, e.g., a detailed discussion of the pros and cons of LMP can be found) and elaborates on the question how LMP could be implemented in one or several European countries and how possible implementation pathways may look like in a coupled European system. Moreover, the whitepaper describes preparatory steps that are necessary for the introduction of LMP, and – at the same time – create advantages for countries under both, a nodal and zonal market design. All in all, the results and outcomes of the whitepaper shall support the market design transition in Europe and, thus, the integration and activation of flexibility potentials to foster a fast reduction of CO2 emissions through a better use of VRE. Therefore, the whitepaper contributes with concrete policy measures to the overarching vision of a future European electricity market design that bases on low-carbon technologies and enhances welfare and fairness, while ensuring economic competitiveness of Europe.

You'll never share alone: analyzing carsharing user group behavior

The rapidly developing concept of carsharing is an essential and scalable part of sustainable, multimodal mobility in urban environments. There is a clear need for carsharing operators to understand their users and how they use different transportation modes to intensify the development of carsharing and its positive impacts on the environment and urban cohabitation. We foster this understanding by analyzing usage data of carsharing in a medium-sized German city. We compare user groups based on individual characteristics and their carsharing usage behavior. We focus on a station-based two-way carsharing scheme and its relation to free-floating carsharing. Based on different clustering and segmentation approaches, we defined 20 particularly interesting user groups among the carsharing users and analyzed noticeable usage patterns. Additionally, we examined these partially overlapping user groups in the spatial dimension. With these results, we support research and operators in understanding carsharing customers and assessing users’ individual behavior
