and regulating power markets. The EVPP was tested with
the Bornholm power system.
A new 5-min real-time market was developed in the
EcoGrid EU project to provide fast and cost-efficient balancing for power systems with high renewables. The concept is
illustrated in Figure 6. In the real-time market, a real-time
5-min price signal is repeatedly issued to flexible resources
to balance the power system. The demonstration on Bornholm has proven that the customers reacted in a way that
helped balance the power system following a real-time
price signal. There is a significant peak load reduction
potential; the peak load reduction is equivalent to 1.2% of
the Bornholm peak load, and 87% of the reduction is from
the heating demand. From the replication perspective, customer involvement is the key to success.
The main aim of the IDE4L project is to define, design,
and demonstrate an active distribution network that integrates renewable energy sources and new loads, and that
guarantees the reliability of classical distribution networks.
The active distribution network consists of the infrastructure of power delivery, active resources, and active network
management (ANM). It combines passive infrastructure
with active resources, ANM functionalities, and distribution

automation information and communication technology
infrastructure (Repo 2016). The idea of IDE4L is to develop a
concept of distribution network automation exploiting
existing automation systems to monitor the whole distribution network and control DERs. The overview of the
IDE4L automation solution is shown in Figure 7.

Real-Time and Microgrid Test
Platforms of PowerlabDK
PowerLabDK is a unique platform for basic research and
large-scale and full-scale experiments for smart grids and
intelligent energy systems. It consists of four parts: The
High Power Lab at the DTU Ballerup campus; the Intelligent Control Lab (ICL), Electric Lab, High Voltage Lab, and
Power Student Lab at the DTU Lyngby campus; a largescale test system (SYSLAB) and the PowerFlexHouse facility at the DTU Risø campus; and a full-scale power system
on Bornholm. The ICL and SYSLAB are described to show
the possible test set-ups for off-grid solutions.

ICL
The ICL is built on the real-time digital simulator (RTDS).
The RTDS can accurately simulate the steady-state
