SYSLAB – Distributed Energy System Laboratory
• SYSLAB is a platform for Decentralised Energy Resources research and testing
• It is a flexible experimental setup up
• It includes several production and consumption units
• It has embedded computing power and flexible communication
• It has very flexible control possibilities
• It can be extended
7kW 11kW
13*1kW 48kW/60kVA
9kWh 55kW 15kW/120kWh

Main parts of SYSLAB
• Production and consumption equipment
• Measurement system• Computer network• Node-computers with linux• Software: agent platform,
measurement database

Electrical layout of SYSLAB
• Flexible grid configuration• Autonomous grid• Units can be tested in under
various grid conditions• Suitable for component as well
as system tests• Very flexible control• Control computer at each
component• Communication network• Agent-based software
infrastructure

Execution platform
• Interactions between entities defined in software, not hardware
• easier transition between the current system (static hierarchy) and future paradigms, as research progresses

What can SYSLAB be used for
• System control concepts– Distributed and decentralised control– Exploitation of demand response/demand side management– Communication – what has to be communicated, what happens when
the communication is interrupted• Interaction between components in a heterogenoues system
– Wind, Solar, Electrochemical Storage, Hydrogen system, Conventional production, Loads etc.
• Testing of components– Characterisation– System properties

Examples on activities in SYSLAB
• System Control: – Self-organising distributed control of a distributed energy system with
a high penetration of renewable energy (EnMi)• Energy Storage:
– Characterisation of Vanadium redox-flow batteries (PSO)• Flexible Consumption:
– FlexHouse

Self-organised distributed control of a distributed energy system with a high penetration of renewable energy• Activation of distributed
resources• Utilisation of local resources• Seamless integration with
system control (plug and play)• System is able to handle new
components as well as new configurations e.g. caused by faults
• Agent-based control of power system
• Agents are software objects that are
– Connected to the real world
– Pursuing a goal– Interacting with other
agents

• Battery system includes:• Cell stacks (340 cells in
total)• Electrolyte and storage
(26500liter)• Balance of plant (pump,
pipes, etc.)• Control and communication
unit• Four quadrant AC/DC power
converter
• Total price: 750.000 DKK

Round trip efficiency : electricity → storage → electricity
• Power Converter efficiency– ~85%
• Auxilliary Power Consumption– ~1.4kW (almost constant)
• Cell stack efficiency high• Converter losses are high• Auxilliary power consumption is
relatively high
Cell stack (DC power)

Power FlexHouse
• Provide a software and hardware platform for implementation of controllers for flexible consumption
• Study control strategies for flexible loads, sensor requirements, modelling
• Investigate how users can interact with system
• Enable investigation of the interaction between control capabilities of a consumer load and the requirements of the rest of the system
• Communication interface between load and system:
– Which information to exchange,
– How to communicate strategies,
– Links to existing communication protocols

Plug-in Hybrid Cars/Electric Vehicles
• RE in transport• Coordination control of
charging/discharging to support grid• Intelligent control
– Driving patterns– Forecasting techniques for
charging decisions– Charging depending on grid
state
• Extended battery– 9kWh LiFePO4 (48*24 cells)– 1kW charging power– 50km range as EV
• Future– Vehicle2grid hybrid car: Bi-directional
converter– Support grid
