Reliability and Resilience in Low-carbon Power Systems
Virtual distinguished lecture by Prof. Pierluigi Mancarella
Our understanding of the classical reliability concepts of security and adequacy is increasingly being challenged by: (a) growing shares of inverter-based resources and variable renewable energy technologies that call for new operation and planning approaches, particularly to deal with decreasing levels of inertia and system strength, larger reserve requirements, and increasing volumes of distributed energy resources that are not “visible” to the system operator; and (b) the more frequent occurrence of extreme, high-impact low-probability events (e.g., driven by climate change), with potentially catastrophic impacts.
In this IEEE PES Distinguished Lecture we will discuss how there is a need for introducing new analysis and modelling frameworks to deal with the increasing fragility of low-carbon grids and exposure to extreme events. The key desirable features of such frameworks will be presented for both operation and planning and from both technical and economic/commercial perspectives, along with metrics, methodologies and modelling tools that can help make future systems more secure, reliable and resilient.
The key question that will be asked is whether the grid should be made “stronger” (e.g., through component hardening), “bigger” (more redundant, through investment in new transmission/generation asset) or “smarter” (through new technologies and operational practices).
Besides different examples taken from the speaker’s several international projects in the area, the South Australia “Black System” event of September 2016, the Australian system separation event of August 2018, the UK demand disconnection event of August 2019, and the Texas power crisis of February 2021 will be taken as “textbook” case studies to practically illustrate some of the general concepts presented.

Biography:
Pierluigi Mancarella is Chair Professor of Electrical Power Systems at the University of Melbourne, Australia, and part-time Professor of Smart Energy Systems at the University of Manchester, UK.
Pierluigi obtained the PhD degree in Electrical Energy Systems from the Politecnico di Torino, Italy, was a Research Associate at Imperial College London, UK, and held visiting research positions at Sintef/NTNU in Norway and NREL in Colorado, as well as visiting professorships at Ecole Centrale de Lille in France, the Universidad de Chile, and Tsinghua University in China.
In the last 10 years Pierluigi has been involved in/led some 60 research projects and consultancy and professional activities in the UK, Europe, Australia, and internationally, in the areas of multi-energy systems, grid integration of renewables, energy infrastructure planning under uncertainty, and reliability and resilience of low-carbon networks.
Pierluigi is author of several books and book chapters and over 300 research papers. He is an Editor of the IEEE Transactions on Smart Grid and the IEEE Transactions on Power Systems, an IEEE Power and Energy Society Distinguished Lecturer, the past Chair of the Energy Working Group of the IEEE European Public Policy Initiative, the Convenor of the Cigre Working Group C6/C2.34 “Flexibility provision from distributed energy resources”, the lead of the “Regulatory Framework” Task of the Cigre Working Group C4.47 “Power system resilience”, and the Technical Chair of the 2022 International Symposium on Microgrids. Pierluigi is also the recipient of a 2018 International Newton Prize for his research work on power system resilience to earthquakes in Chile.
