Power System Dynamic Modelling and Analysis in Evolving Networks

This Green Book is an essential resource for power system engineers seeking comprehensive information on contemporary power system dynamic modelling and analysis. With today's rapid adoption of inverter-based resources and the resulting changes in power system dynamics, this book compares conventional power systems with evolving power systems characterized by high shares of grid-connected and distributed inverter-based resources. It covers dynamic phenomena, analysis methods, simulation tools and enablers required for secure and reliable system planning and operation.

Starting with an overview of power system studies and associated analysis tools, the book provides modelling requirements for various power system components, including existing and emerging technologies. It includes practical examples from real-world power systems worldwide that act as step-by-step study guides for practising engineers and provides knowledge to apply in their day-to-day tasks. Additionally, the book emphasizes the importance of power system model acceptance testing and validation, providing practical examples of various testing methods.

Written with practising power system engineers in mind, this book minimizes the use of advanced mathematics. However, relevant sources for those interested in learning more about mathematical concepts are provided. Overall, this book is an invaluable resource for power system engineers navigating contemporary power systems.

The Study Committee C4 (Power System Technical Performance) is responsible for advanced methods and tools for analysis related to power systems. Areas of attention include:

Power Quality Performance: Continuity of end-to-end electric power supply and voltage waveform quality (magnitude, frequency, symmetry). Analysis covers emission assessments from disturbing installations, measurement and simulation methods, identification of quality indices, monitoring techniques, immunity of sensitive installations, and mitigation techniques taking into account a co-ordinated approach across all voltage levels.

Electromagnetic Compatibility (EMC): High frequency disturbances on the end-to-end electricity supply and all disturbances (HF or LF) reaching equipment other than through the electricity supply. Studies include measurement and simulation methods. Health effects related to low frequency EMF are however excluded.

Power System Dynamics: Development of advanced tools and new analytical techniques for assessment of power system dynamic/transient performance, security, design of controls and modelling of existing and new equipment, real time stability evaluation and control.

Lightning: Analysis of lightning characteristics and interactions of lightning with electric power systems and equipment, including protection in MV and LV networks against lightning, and their standardisation.

Insulation Co-ordination: Methods and tools for insulation co-ordination and electromagnetic transient analysis in electric power systems and equipment, contributing to optimisation of their cost and reliability.

Zia Emin received his BSc in Electrical & Electronics Engineering from the Middle East Technical University, Ankara, Turkey and MSc and PhD degrees from The University of Manchester, Manchester, United Kingdom. He has worked as a power system engineer specializing in the planning and development of electric power networks, initially with National Grid and later with Parsons Brinckerhoff (later WSP) and PSC. Since 2023 he is working in Electric Power Research Institute (EPRI) as a technical executive. He has extensive knowledge in all aspects of power system modelling including steady-state, frequency and time domain modelling and substantial experience in harmonic performance specifications of power electronic interfaced devices (HVDC converter stations, FACTS, renewable generation connections etc).

He has been active in many CIGRE (International Council on Large Electric Systems) working groups as member, task force leader and convenor within system technical performance area. He received the CIGRE Technical Committee Award in 2013 and the Distinguished Member award in 2014. From 2016 to 2022 he was the chairman of CIGRE SC C4 and its Strategic Advisory Group. In this role as CIGRE Study Committee Chairman he was responsible for the formation, operation, and deliverables of around 40 highly specialized technical working groups. He was also a member of the CIGRE Technical Council at international level and the past chair at national level (CIGRE-UK). Currently he is a member of the CIGRE Strategic Advisory Board.

He is a Fellow of the Institute of Engineering and Technology (IET - UK), a Senior Member of IEEE, a Distinguished and Honorary Member of CIGRE, a European Engineer, and a Chartered Engineer in the United Kingdom.
