Opening and information session

Region 8 PES Chapter Chairs Training Croatia 14th October 2024 - ISGT Europe

The transmission systems are heading towards hybrid using high-voltage AC and DC connections. Power electronic converters contribute to significant changes in the operation and control of the system, its stability, and robustness. For the design of a hybrid electrical grid and preparation for its physical deployment, real-time simulations and hardware-in-the-loop testing are a must. This tutorial covers the design aspects of the power electronic converters used for DC applications (MMCs) and control of the power systems with the high penetration of renewable energy sources using the real-time hardware, RTDS©. The tutorial will use RSCAD/RTDS open-source libraries during the “hands-on” sessions in RSCAD/RTDS. The participants will be divided into 10 groups, supported by a computer with installed RSCAD and secured access to RTDS cores. Furthermore, one RTDS NovaCor (10 cores) will be present, and the participants will be able to see its operation and connection.

This panel will present final results of the Norwegian-Swedish research project NEWEPS - Nordic Early Warning Early Prevention System. The research conducted in the NEWEPS project are intended to provide the Transmission System Operators (TSOs) with increased insights into functional and non-functional requirements on Wide-Area-Monitoring-Protection-and-Control (WAMS / WAMPAC) systems. The main focus of the work has been on increased situational awareness for operators, development of novel Energy Monitoring System (EMS) solutions and evaluation of visualization techniques. Towards the end of the NEWEPS project, a road map will be created with the intention to support the development and future implementation of WAMS and WAMPAC systems at the Swedish and Norwegian TSOs. The main messages of this panel relate to the lessons learned, main conclusions and results, and the proposed way towards implementation. At the panel, the following issues to be addressed: • Background and needs of a Wide-Area monitoring control and protection system • Research and development of Voltage stability indicators • Research and development of identification and classification of Natural and Forced oscillations • Research and development of Wide-Area-Control concepts • Research and demonstration of Advanced vizualisation concepts • Research and demonstration of a Platform for monitoring applications and operator interaction

The development of reliable and resilient HVDC dominated power grids in the coming decades presents many challenges, necessitating a range of new analysis tools, models, and control approaches. The Horizon Europe and UKRI funded HVDC-WISE project seeks to address many of these challenges, through the development of an integrated reliability and resilience analysis framework for widespread hybrid AC/DC grids. In this session project participants will discuss methodologies and tool developments, modelling challenges, and control frameworks that have been developed within the project to date.

Vice President, Quanta Technology Panelists: · Dr. Luka Strezoski, University of Novi Sad, Serbia · Ambra Sannino, Vice President R&D Vattenfall, Sweden · Dr. Martha Symko-Davies, NREL, United States · Annika Moman, WSP, Gothenburg, Sweden · Par Lundstrom, Senior Policy Advisor, The Swedish Installation Federation · Brittany McKannay, Director, Electric Engineering, Pacific Gas and Electric Company

There are major discussions worldwide on how the production of clean fuels, such as hydrogen, could facilitate the whole-energy system decarbonization. From a power system perspective, green hydrogen production results in massive grid integration of electrolyzers, that needs to be considered in power system analysis. This tutorial presents the modelling foundations of utility-scale hydrogen electrolyzers with alkaline and proton exchange membrane (PEM) technology, including electrolysis stack models, power electronics interface (PEI) and control, thermodynamics, hydrogen production formulations, and operational constraints in downstream hydrogen process/buffer, required for system-level steady-state and dynamic studies in both transmission and distribution grids. Possible PEIs for grid integration of electrolyzers will be discussed, along with the associated control schemes in particular grid-forming load control. It will be discussed how and to what extent electrolysis plants could impact system stability and operation, from both steady-state and dynamic perspectives
