Introduction
▪ Exchange and discuss results from ERIGrid Work Package WP09 (JRA3)
of the ERIGrid project and from three other initiatives
▪ Getting feedback for the following questions
– Will smart grid system level testing become important in (near) future?
– What are possible solutions (testing setups and procedures) for getting
valuable and correct test results?
– What are the challenges and minimum requirements for the labs,
performing such smart grid system level tests?
– Is a guideline describing a common/harmonised
way of smart grid system level testing useful?

Background/ Motivation for WP 09
▪ Challenges for pure lab /field testing of SG components
– Incr. compl. of cyber-physical energy systems (CPES)
– New components (RES, EV, heat pumps, etc.) & fields
of applications (e.g. power & heat supply, transport)
– System services of RES are mandatory (EU Network
Codes RfG)
– New business models (VPP)
– Digitalization of power systems (remote control, metering)
▪ Advantages of an Integrated lab based validation approach (incl.
real-time simulation and Hardware-In-the-Loop (HIL) test setups)
– Testing of realistic fault conditions or rare network events
– Flexibility in changes of grid and component parameter
– De-risking field testing by well adapted testing
environment and conditions

Aims and Objectives of ERIGrid WP 09
▪ Develop and setup and integrate lab-based research infrastructure for
system-level analysis of components/small-scale systems regarding
– Harmonized Smart Grid ICT Systems/Protocols
– Improved HIL methods/algorithms for Smart Grid
– Combining of HIL and RT-Simulation for system integration
– Harmonized testing scenarios and methods for system integration

Highlights of ERIGrid WP 09Harmonized Smart Grid ICT Systems/Protocols
▪ Reference model for controller interfaces
across ERIGrid research infrastructures
and beyond was developed
▪ Model facilitates a common description
of communication and control in smart
grid laboratories
▪ 5 generic control levels (C1-C5)
▪ 5 generic levels of external user
equipment (X1-X5)
▪ 5 generic control levels of lab
infra-structure (D1-D5)
▪ 8 comm. interfaces (R1-R4, L1-L4)
▪ 12 interfaces for data (E)xchange (E1-E12)

Highlights of ERIGrid WP 09Harmonized Smart Grid ICT Systems/Protocols
▪ Harmonized naming convention for laboratory
objects and signals across laboratories was
developed (analogue to IEC61175), consisting of
– Object Naming Convention<ObjectType>_System[.Subsystem][...][_AssociatedSystem][.Subsystem][...]
– Signal Naming Convention<SignalType>_<Domain>_<Signal>[.<Subsignal>][...]
– Object Type Names

Highlights of ERIGrid WP 09Harmonized testing scenarios & methods
▪ Test description map for two test cases (TC) had
been elaborated based on holistic test cases
– TC#1: Decentralized (voltage) control and
– TC#2: Centralized Voltage Control
▪ Single Site: Test involves only one research
infrastructure (RI)
▪ Multi Site: Test involves multiple RIs,
simultaneously or not.
▪ Single Test: Unique test, involving only one RI
or multiple RIs simultaneously
▪ Multi Test: Multiple tests (repeated) in the same RI
or in different RIs, (i.e. testing chain)
