WS3: Open System for Energy Services in future Smart Grids

Scope & objective:

Today mass presence of distributed energy resources (DERs) connected to the grid is seen as complicating network management and having adverse effects on grid reliability and robustness. Due to the rising presence of DERs in the coming years it is essential to have concepts their sustainable integration into the grid allowing them to provide grid support by offering matching energy services for a given critical grid situation. Such concepts must address the following questions:
•    How can resource providers of DERs such as electric vehicles, photovoltaic systems, wind power plants and combined heat and power plants be enabled to make their resources visible in the energy market on a discriminatory-free basis?
•    How to enable aggregators to access DERs in order to spontaneously aggregate their energy services (e.g. provision of flexibility) and hence relieve stress on the grid?
•    How to ensure that energy is produced, delivered and managed at lowest cost in grids with an ever growing share of renewables?
The European research project OS4ES (Open System for Energy Services) addressed these issues and has built a generic, non-discriminatory and multivendor-capability ICT platform based on international standards for easy cross-linking distributed energy resources with Smart Grid actors and hence facilitating the discovery and use of demand/supply flexibility that is scattered among a multitude of DERs. It provides a complete tool chain that manages the collaboration framework between energy resources in the field and market actors who wish to easily discover, negotiate their usage and dispatch them for providing energy or ancillary services to the respective markets.

The workshop addresses conference delegates eager to get to know a powerful tool for future Smart Grid management with open-source components that can be adjusted to the needs of the respective Smart Grid actor and to see demonstrations of its application. Besides, discussions also considering alternative approaches will help to elaborate the pros and cons of the presented research project concept and enable workshop participants to decide if one or several of the OS4ES open-source components or even the entire platform also fit their needs.

Topics of interest include the following:

•    Energy Service concept and OS4ES architectural design (incl. security)
•    OS4ES data hub for Smart Grid actors and DERs
•    Blockchain concept as an alternative approach for the OS4ES data hub
•    IEC 61850 communication stack and its connection to legacy systems
•    Implementation of the OS4ES architecture in prototypes
•    Demonstration of the OS4ES platform in prototype applications for lab and field tests


Andrea Schröder studied Electrical Engineering at the University of Applied Science in Mannheim. Since October 1995 she has been working with FGH starting in the software development department where she was responsible for programming and maintaining the data base of the power system planning tool INTEGRAL, INTEGRAL trainings and seminars and the enhancement of the German DVG data model for power system calculations. In August 2001 Mrs Schröder moved to the department system studies. There, she performed system studies with INTEGRAL and worked on the FGH-lead EU research project ScadaOnWeb. Since 2005 she has been working in the department power equipment technology and has been involved in various national and international research projects focusing on smart grids and the IEC 61850 standard. Besides, Mrs Schröder is a member of the international working group IEC 61850 TC57 WG17 (Communication networks and systems for power utility automation) and its German mirror committee. In this function, she is currently involved in the German activities of the FNN (forum network technology/network operation - a body of VDE) focusing on setting-up an IEC 61850 data model for a control box for distributed resources rolled-out together with Smart Meters and their corresponding Smart Meter Gateways in Germany from 2017 on.

Jörg Benze studied electrical engineering at the Technical University Darmstadt and obtained a doctorate degree in computer science from the Technical University Ilmenau. He has over 20 years of experience in the telecommunication and internet industry. Since 2006, he works as principal consultant in the areas of innovation and industrial sector business development at T-Systems MMS and currently focuses on (web-) technologies for the future "Internet of Energy", especially "Smart Grid Information Security". He is an expert for service delivery platforms (including the necessary safety concepts) and software testing for the complete life cycle of web-based Smart Grid applications


Wolfgang Renz obtained his Physics Degree with the founder of Synergetics Hermann Haken at the Stuttgart Univeristy. 1983 he was awarded the Borchers medal for his Dissertation in the RWTH Aachen. In total he worked  for 15 years in basic research, at the Rutherford Appleton Lab (Oxford, UK), at the Jülich Research Center and at the Fraunhofer IZB Bonn Birlinghoven. Since 1991 he works in Computer Science, particu-larly in Software Engineering, Simulations and Middleware. In 2009 he co-founded the Energy Informatics working group in the German GI. He has been leading several projects with a focus on smart distributed energy systems, electricity and heat. He is reviewer for several institutions and author of more than 100 publications.

Tim Dethlefs, M.Eng. is a doctoral candidate and research associate at the Multimedia Systems Laboratory (MMLab) at the University of Applied Sciences Hamburg (HAW Hamburg). His research interests include distributed systems and infrastructures for Smart Grids. Currently, he is working for the EU-FP7 project “Open System for Energy Services” (OS4ES). Tim Dethlefs received his Master of Engineering in information- and communication technology (ICT) from the HAW Hamburg in 2014.
