ERIGrid Spring School: Introduction to Real Time Simulation Environment and Application in Sustainable Energy Systems

ERIGrid Summer School on Validation Methods for Distributed Control Strategies

The “ERIGrid Summer School on methods for validation of distributed control strategies via implementation in the physical laboratory” was hosted on 27-31 August 2018  at the Technical University of Denmark.

Coordination and control are critical in the development of future energy networks. However, many promising concepts fail to bridge the gap from theory to practical application. Experience from actual implementation can be crucial in focusing your research and development. Implementation under realistic conditions is crucial for maturing the solutions as well as convincing further stakeholders.

The summer school focused on methods for validation of distributed control strategies by implementation in the physical laboratory. Participants implemented a control system in SYSLAB, one of the ERIGrid laboratories provided for free access.

In this summer school, participants:

– Learned to formulate test specifications to develop a relevant and realistic test setup
– Experienced the steps along the path from a new control concept to maturing it for validation in a laboratory experiment
– Gained an understanding of how carefully planned Design of Experiments will yield a better understanding of the limits of proposed solutions

Tutorials introducing design of experiments are available here.

ERIGrid 1st Winter School: Metrology for Smart Grids and Testing (23-25 January 2018)

Measurements for smart grid applications are sometimes overlooked and assumed to give the correct answer. On 23-25 January 2018 the University of Strathclyde hosted the 1st ERIGrid Winter School “Metrology for Smart Grid Applications and HIL Testing”. Organised in collaboration with MEAN4SG and the National Physics Laboratory (NPL), the school provided PhD students and young researchers with a mixture of lectures, practical laboratory interactions with ongoing research projects, and a 1-day hands-on laboratory session.

A series of lectures given as part of the winter school focus on the awareness of the measurement accuracy and also provide an introduction into accurate measurement techniques, such as phasor measurement units (PMU), and the testing of the accuracy of such devices. Furthermore, measurement of uncertainty is a relevant aspect to consider when developing simulation models and performing measurements.

Real Time Digital Simulator Lab (RTDS)Co-Simulation for smart grids

The ERIGrid project explores the potential of co-simulation based on the Functional Mock-up Interface (FMI) standard for smart grids research. This presentation – “FMI – Functional Mock-up Interface. Specification and Applications.” by E. Widl (AIT) – provides a brief overview of the FMI specification and some of the FMI-compliant tools used in ERIGrid.

The following two documents present the Mosaik co-simulation framework. The main goal of Mosaik is to couple existing simulators in a common environment in order to perform a coordinated simulation of a given (smart grid) scenario.

Holistic testing

The holistic test specification method was developed in ERIGrid to structure and guide the ERIGrid holistic validation approach. This test description method has been adopted into several H2020 projects. The lecture here is based on lectures held at a summer school and ordinary teaching at the Technical University of Denmark.

The slides “How to Formulate a Test Specification” introduce the concept of holistic test specification, in principle, and by example, contrast it from use cases and summarise the related system configuration description method

PHIL and CHIL simulation for education, research and testing

Laboratory education in the power systems domain is usually performed with software simulations and more rarely with small hardware setups with limited capabilities (contrary to other domains e.g. electric machines). On 10 October 2018, RTDS European Users’ Group Meeting took place in Genk (BE), where Panos Kotsampopoulos of NTUA talked about the advantages of PHIL and CHIL simulation for education, research and testing.

Virtual Lab

The Virtual Lab is an online educational simulation tool that mimics the operation of the actual laboratory microgrid of ICCS-NTUA. A mathematical model of the laboratory microgrid has been developed along with a friendly Graphical User Interface. The tool aims to familiarize the user with two aspects of Smart Grids through two distinct experiments: Voltage Control and Microgrid Operation.

Experiment #1: Voltage Control

The main objectives of this experiment are to demonstrate the voltage rise issue that can occur in distribution networks, due to the high production of Distributed Generation (DG) (mainly Photovolta-ics), but also the ancillary services that modern DG inverters offer in order to mitigate the afore-mentioned voltage rise.

Experiment #2: Microgrid operation

The objective of the second experiment is to familiarize the user with the concept of microgrids in both grid-connected and islanded operating modes.
