Managing data and complexity in energy systems

A decade ago, pioneers across the world began to think of information and communication technologies as key contributors to the transition of our energy system to a network of sustainable low-carbon producers and consumers. This idea was dreamt up some time before, but with recent technological advances in terms of computing power, communication bandwidth and significant reduction in system costs, more and more approaches became feasible. The worlds of electrical engineering on one side and informatics/information and communication technologies on the other side had a new connection point, which was called “smart grid”. In those days, strong day-to-day efforts were required to explain the motivation for smart grid research.
In subsequent years, the field experienced a strong push with rising interest from industry and even energy infrastructure operators. Many basic concepts such as demand response or voltage control became common sense. In addition, from the beginning on, the research field was well supported by research agendas throughout Europe, with policy makers demanding and happily adopting better clarity and common definitions.
Some years later, the field had developed from a set of early concepts to a spectrum of component and system solutions of much higher maturity. Many approaches were validated in the field in the frame of national and European research programs such as FP7, e-Energy in Germany or “Energiesysteme der Zukunft” in Austria. With this, a substantial research community had developed. It was time to identify the field of “Energy Informatics” as a full-grown research field.
Young researchers entering the field today will have very different experiences compared to the situation ten years ago. The available literature now exceeds by far what can be overseen by a single person. However, many concepts are clearly described now, taught in lectures and defined in books. It is no longer possible to compare innovative solutions to the old or “conventional” power system; applications of Energy Informatics have found their way into most aspects of design, planning and operation of power systems where required. The vision of a technological “smart grid” revolution has been replaced by the insight that there will be an incremental update of existing infrastructure with a large number of different innovative aspects applied to different parts of the system. Furthermore, with the D-A-CH \(+\) Energy Informatics conference series a researcher today has a good starting point to learn about important research challenges and to network with other researchers in the area.
The objective of D-A-CH \(+\) Energy Informatics 2016 is to further support this process of a research-based development and implementation phase of adequate information and communication technologies (ICT) and to foster the transfer between academia, industry, and service providers in the D-A-CH region Germany, Austria and Switzerland in close cooperation with other European partners. The conference addresses both scientists and practitioners.
The guiding topic of this issue is “Managing Data and Complexity in Energy Systems”. A strong contribution from Informatics is required to handle the sharply growing complexity of energy systems with a large share of renewable energy sources and more and more dynamic operation paradigms. At the same time, it is mandatory to gain deeper insights into the behavior of the infrastructure and its users, taking into account the resulting challenges in privacy and data analysis. All submitted papers focus on this field and can be categorized into four main topics:
Energy networks—digitalization of electricity network infrastructure, integration of renewable energies, behavioral and forecast models for system users, modelling of future scenarios.
Mobility–coordinated charging management for e-cars and second use of batteries.
Buildings —optimization of the interaction between building management systems, HVAC and energy networks, innovative techniques for energy management.
Cross cutting—Privacy enhancing technologies, validation of networked smart grid systems, analysis of energy data, market modelling.
We would like to thank all authors who have submitted their work to the conference. Following the successful conferences in Oldenburg 2012, Vienna 2013, Zurich 2014 and Karlsruhe in 2015 respectively, 48 manuscripts have been submitted in 2016, whereof twenty revised versions have been included in this issue.
D-A-CH \(+\) Energy Informatics is a yearly event organized on joint initiative of Smart Grids D-A-CH—a cooperation of the German Federal Ministry for Economic Affairs and Energy, the Austrian Ministry for Transport, Innovation and Technology, and the Swiss Federal Office of Energy (see also http://www.smartgrids-dach.eu/).
