Webinar Abstract: IEA TCP WIND Task 25 “Design and Operation of Energy Systems with Large Amounts of Variable Generation” compiled Recommended Practices for power system impact studies, traditionally called wind and solar integration studies. This provides research institutes, consultants, and system operators with the best available information on how to model and study power and energy systems with large amounts of wind and solar energy. The Recommendations are presented as checklists that are also useful in benchmarking any integration studies: what has and has not been taken into account when performing a simulation study. The Recommended Practices contain the following sections: Input data; Scenario set up; Adequacy; Operational impacts; Dynamics; Analyzing and presenting the results. Each section highlights the issues with the main recommendations, for small/medium wind and solar shares in the power system and also for wind and solar dominated systems.

In this webinar, Recommended Practices checklists are compared with modelling practices applied in a study of electrification of the transport and industry sectors in Sweden. The challenge of addressing all aspects of wind and solar integration calls for several simulation tools to analyze aspects such as reserve requirements, power flow and resource adequacy. A detailed investigation into consequences of simplifying or omitting parts of the recommended practices is helpful for modelers to prioritize and better understand the limitations of their results. The recommendations should not be too rigid to hinder creativity and development in the field – they can be considered as work in progress, evolving as the model framework and available data develops. Using the recommendations to better understand which questions a study can answer and as basis for discussing modelling results, they can help us build confidence in models as tools to prepare for energy system transformation.

About the Speakers: Dr. Hannele Holttinen is currently Professor of Practice at Aalto University  as well as RDI Lead, Energy systems at CLIC Innovation Oy. Through her own consultancy Recognis Oy she continues coordinating international research on grid integration acting as Operating Agent of IEAWIND Task 25/63 as well as working for G-PST (Global Power System Transformation Consortium) as Pillar 5 lead. She has her MSc and PhD from Helsinki Technical University, where she is Docent since 2014. She worked previously at VTT Technical Research Centre of Finland for more than 25 years in different fields of wind energy and energy system integration research, last years as Principal Scientist. Her main interests are on the impact of wind and solar on power and energy systems. She has chaired IEAWind in 2011-12, and has been active in European Wind Energy Platforms ETIP and TPWIND as well as in Nordic energy research.

Lisa Göransson is associate professor in energy systems at Chalmers University of Technology, Sweden. The focus of her research is dedicated to strategies to manage variations, sector coupling and energy systems modelling. This work is carried out together with  six PhD students under her supervision, and include collaborations with electrical engineering, mathematics, computer science and social science. Her extensive work on strategies to manage variations in the electricity and energy systems has resulted in a functionality-based framework to support the choice of strategies in different system contexts.

Damian Flynn is an Associate Professor in Power System Operation and Control at University College Dublin, Ireland. His research interests focus on power system dynamics, grid integration of renewables, and power generation control. He received MEng (Master of Engineering) and PhD degrees in Electrical & Electronic Engineering from The Queen’s University of Belfast, Northern Ireland. He has published more than 300 research papers, books and technical studies, and he has been involved in various European Union projects, including Migrate, Sysflex, WinGrid and Mopo. He represents Ireland for IEA Wind Task 25 (Design and Operation of Energy Systems with Large Amounts of Variable Generation) and Task 58 (Offshore Energy Hubs).
