Europe's energy goals require reliable and comprehensive integration of renewable energy at all network and voltage levels. The co-ordination between transmission and distribution service operators necessary for accomplishing this goal has been the responsibility of national network operators to date. Power transmission across borders has been taking place only at the high-voltage level thus far.
The Callia project highlights the extent to which direct load compensation for the neighbouring distribution networks of two states simplifies the integration of renewable energy.
Local compensation for renewable energy at the distribution network level could minimise the limitations placed on renewable energy systems, reduce the load of the transfer points between transmission and distribution networks and simplify the compensation between local distribution networks and higher-level transmission networks. In addition, energy losses are reduced because local generation and consumption in regions along international borders can be balanced without having to work through all of the voltage levels in an "up, over and down" path.
The result would mean efficient integration of decentralised energy and stabilisation of the entire European energy network.
C/sells provides an extensive window into the energy use in the solar belt across Southern Germany. The project demonstrates how an intelligent network can ensure supply with solar energy and other renewable energy in a way that is cost effective, secure, environmentally compatible and participatory. At a project volume of €100 million, more than 60 partners from industry, power industry and science are looking to implement a cellular energy system in Baden-Württemberg, Bavaria and Hesse in the next four years. devolo AG is taking an active part in this project as a project partner.
The showcase region of WindNODE includes the transmission service operator 50 hertz network area and provides a real-life laboratory for a complete energy system. The central goal of WindNODE is to set the standard for the networked energy system of the future.
As a pioneer for renewable energy, the WindNODE region already meets the development goals set by the German government for 2025 with renewable energy making up 45% of consumed energy. Some regions have even surpassed the government's goal for 2050 (renewable energy at 80% of power consumption).
The consortium has more than 70 partners and links throughout politics, the economy and society, receiving prominent support from the government leaders in all six participating German federal states. devolo AG is a consortium partner in this large-scale project, acting as the smart grid hardware manufacturer.
As the number of decentralised wind and solar energy systems with fluctuating power infeed potential continues to increase, the large-scale enera project is looking to make important gains in the successful integration of these energy systems by establishing smart grids covering extensive areas. The project involves 75 renowned companies, institutes and political players from the Northwestern Germany model region.
The implementation of intelligent technologies (particularly the interaction between energy infrastructure and information/communication infrastructure in a smart grid) will make future energy systems significantly more efficient. This will allow renewable energies to play an even more important role in the energy mix, paving the way for a sustainable power industry.
The increasing integration of decentralised feeders and loads, particularly in the distribution network level, poses new challenges for network operation and planning.
In the future, networking and communication of a wide variety of power frequency components from the areas of status monitoring, control and regulation will be required. To ensure secure and reliable network operation, it is vital that communication interfaces and structures, particularly those with diminished physical access protection (on generation systems for end customers), do not cause any external interference in network operation.
The SEnCom project is intended to reveal challenges relevant to security and reliability during integration of the communication infrastructure into the distribution networks and analyse the possibility of external interference in communications systems and its effects on network operation.
This analysis will expand on the current work of devolo AG, RheinMain University of Applied Sciences, Bremen University of Applied Sciences, RWTH Aachen University and the P3 Group.
devolo AG, together with municipal utility Krefeld Netze GmbH and Janitza electronics GmbH, and academic partners, the University of Applied Sciences Düsseldorf and the University of Duisburg-Essen, is researching the application of G3-PLC technology at the distribution network level in the joint project "Measurement of the low-voltage side network state variables in real time" (ENERGIE - Erfassung der niederspannungsseitigen Netzzustandgrößen in Echtzeit). The overarching goal is to determine, using sensors, the network condition at only important strategic points on the low-voltage side and to use this data for network planning and operational concerns of network management. This approach does not conform to the previous concepts that provided comprehensive equipment with smart meters and is currently the only one of its kind. Using mathematical processes (e.g. state estimation), network conditions are to be determined in real time in a location and time-related manner. The results and insights from this project are examined for their relevance to real-world application as part of a real-world field test and statistically evaluated.
The research focus for the SmartLive project is on the user-friendliness of smart home systems. Active incorporation of end consumers ensures that the formulated solutions meet the needs of users.
In this project, devolo is supplying hardware and software (devolo Home Control) and optimising its smart home solution based on the research findings. As a Powerline pioneer, devolo is also lending its valuable experiences with home networking and the smart grid sector. The future integration of power meter data and flexible electricity rates into the smart home represents a significant area of research at devolo. This also includes the development of a control box that can regulate devices such as heat pumps, photovoltaic systems and electric vehicles, thereby integrating them into the smart home.
Smart energy networks need secure communication. Due to the processing and integration of personal consumption data in measuring systems, the legal regulations regarding data protection and data security are particularly strict. They are stipulated by the German Federal Office for Information Security (BSI) as part of what are known as protection profiles and technical guidelines. As part of the joint project "Secure Powerline data communication in intelligent energy networks" (SPIDER), leading companies, research institutes, colleges and universities are researching and developing concepts for secure powerline-based data transmission in future intelligent energy networks. Innovative approaches, such as Trusted Network Connect, continuous integrity measurement, and secure boot processes are characteristics of already developed prototypes. Working closely with renowned providers of relevant administration software, project partners ensure the integration into an overlaid back-end infrastructure. The project concluded with real-world field tests and the analysis of these tests.Link to project page (only german)

New technical solutions are developed in close cooperation with end users in what is called the "Living Lab", i.e. very close to the real-world application. The objective of the project is to merge the requirements on operational information systems for managing, measuring and processing environmental data with new smart energy technologies and real-time systems. Based on Powerline communication, the near real-time measurement of environmental and energy data and visual processing make a critical contribution to optimising the control and management of energy consumption.Project website
As part of the Eureka/Celtic+ initiative, the EU-supported research project called ACEMIND (Advanced Convergent and Easily Manageable Innovative Networks Design) is aimed at simplifying the installation and use of smart home components—regardless of the underlying communication technology. In quite specific terms, ACEMIND is also seeking to provide corresponding terminal devices already equipped with the improved self-management capability of the network. Furthermore, these products are intended to enable convenient remote management for network operators as well. The German participants, devolo AG and IHP, have also organised themselves within the "AUTOCONFIG2.5" project in the funding program of the German Federal Ministry of Economics and Technology (BMWi) called "The Central Innovation Program SME" (Zentrales Innovationsprogramm Mittelstand - ZIM), forming the basis for even closer collaboration with each other and in the ACEMIND project in the process.Link to press release
Together with the University of Duisburg-Essen, devolo AG developed an E-Mobility charging box that—along with the pure charging process—also allows for bidirectional data communication between the electric vehicle and the charging station. Powerline Green PHY technology is used to do this. This technology enables IP-based broadband data exchange, such as is needed, for instance, for transmitting entertainment data or updating navigation devices.Link to press release
The objective of this project was to implement Powerline-based data transmission that meets the requirements of future intelligent energy networks. As part of a comprehensive field trial, devolo and Vattenfall Europe Metering GmbH tested various measurements and inspected the performance of G3-PLC modems in real-world use. The expected ranges and data rates were surpassed easily. The experience in G3-PLC technology and results obtained in this project generally indicated that the technology more than meets the current requirements for an Access PLC system in terms of typical key performance indicators.
Application scenarios such as Powerline-based data communication in electric vehicles have special requirements regarding durability and costs for PLC communication. In the GreenTrans project, devolo AG developed a PLC module that fulfils the Powerline Green PHY standard and, therefore, meets these requirements.
A very important characteristic of future intelligent energy networks will be the need to transmit a wide variety of data between various user groups. In the TECHNO-PLC project, devolo AG developed an innovative Powerline modem that transmits data over the existing wiring using IP-based communication. The modem developed as part of this project is based on Maxim-G3 technology and uses modulation frequencies between 150 kHz and 500 kHz. This makes it possible to reach a high data rate (typically ~150 kbps) and a large bridgeable range (~1.5 km).
devolo is actively involved in better utilising energy resources and is stepping up the development of innovative smart grid solutions. To this end, the company participated in the European DLC-VIT4IP project. The campaign, which is supported by the EU as part of Europe's Seventh Framework Programme for research, combined the skills, knowledge and experience of twelve international technology companies and universities.
