Description: The Center for Electric Power and Energy (CEE) is a center for research, innovation and education at the Technical University of Denmark (DTU), department of Electrical Engineering. CEE covers a broad range of electric technologies including production, transmission, distribution and consumption of electricity as well the interactions with other energy carrier systems such as district heating. CEE aims at enabling a more intelligent, flexible and automated electric power system that can accommodate the future expansion of renewable energy production and the long term vision of a fossil-free society. CEE holds competences within electric components, electric power systems, automation of complex power systems, electricity markets, end-user interaction and intelligent energy systems. The Energy Systems Operation and Management (ESOM) group is a research group within CEE and performs research covering the development and analysis of new solutions for the management and operation of future distributed power systems with a high share of renewable energy and distributed energy resources. The investigation of future system architectures, centralized as well as decentralized, is part of the research area, with the goal to provide optimal and seamless interaction of all system elements and subsystems. This includes e.g. agent-based solutions and aggregation. The solutions cover novel ICT implementations combined with innovative market-based designs and new grid management methods and important aspect is interoperability of communication and services. ESOM research efforts also cover innovative monitoring, operation and control which enable for example management of grid bottleneck, islanding solutions and microgrids. The research has important interfaces with many of the other groups including research within markets and energy resources, services and control.
PowerLabDK is an experimental platform for electric power and energy laboratory administered by CEE. PowerLabDK supports development, test, training and demonstration of technologies that will contribute to the development of a reliable, cost efficient and sustainable energy system based on renewable energy sources. PowerLabDK is a national GreenLab under the Danish Energy Agency.
The facilities contain flexible test laboratories, large-scale experimental facilities and a complete full-scale power distribution system on the Island of Bornholm which serves as a data source and platform for full-scale and real-life experiments. The PowerLabDK facilities welcome engineers and researchers from industry and academia as well as innovative students.

Facilities
SYSLAB

Description: SYSLAB is an experimental facility designed as a testbed for advanced control and communication concepts for power grids. A 400V, 3-phase grid with a total of 16 busbars and 119 automated coupling points serves as the electrical backbone of the facility and allows flexible use of different grid topologies. A large variety of DER units can be connected at different points of the grid. These include two wind turbines, three PV installations, a conventional (combustion engine) generator, three buildings with controllable heating, vanadium redox-flow and lithium-ion batteries for storage, electric vehicle charging posts and various other types of controllable loads. A back-to-back converter allows power exchange to the campus grid and can be used for equipment simulation or PHIL tests.
All equipment on the grid is automated and remote-controllable. Each unit is supervised locally by a dedicated computing node which acts as a communication gateway. The node computers provide communication between nodes and facilitate the deployment of local controllers. This results in great flexibility with respect to control architectures; standard master-slave control concepts can be tested as well as less traditional approaches such as controllers based on peer-to-peer communication or multi-layered hybrid control systems.
SYSLAB is currently being expanded with a small district heating network in order to study the interaction between energy carriers. A custom-built “heat substation” allows the flexible interconnection and transfer of energy between a number of heat sources, heat consumers and a storage tank.
The lab is in operation since 2005, covers a range of 10-100kVA (and 1x300kVA test bay) and consists of 7 building and various outdoor installations (about 1km in diameter). The laboratory is currently run by 3 technical employees and used by around 25 researchers. An expansion of SYSLAB into a multi-energy research facility by extending the district heating network is planned in the future.
Technical specifications (PDF)
The software infrastructure of the SYSLAB facility has been developed to ease the prototyping of controllers.
Another major development has been installation and commissioning of the heat switchboard with an associated software stack for the control and automation, FlexHeat system. This forms a small local district heating system with coupling to the power system via booster heaters and heat pumps. This allows for more complex controllers to be implemented and tested for multi-energy systems.
