18 November 2021: IEEE PES Webinar on 'Frequency Stability and Resilience Supports from Hydrogen Electrolysers'
The IEEE PES/PELS WA Chapter is organising a webinar by Mehdi Ghazavi Dozein.
There are major discussions worldwide, and particularly in Australia, as to how production of clean fuels, such as hydrogen, from renewable electricity could facilitate whole-energy system decarbonization. There exist, in fact, great synergies between grid integration of renewable energy sources (RES) and hydrogen production. However, RES is also driving power systems into low-inertia conditions, which might raise frequency stability challenges. Potential consequences include frequency-related outages, such as under-frequency load shedding and/or photovoltaic trip. These frequency instability phenomena may combine with severe changes in active power flows through system interconnectors, which can potentially result in interconnectors’ trip and system split, thereby threatening system resilience too.
This talk presents the capabilities of hydrogen electrolysers in provision of fast frequency response, contingency frequency control ancillary services (FCAS), regulation FCAS, and virtual inertia response, while highlighting the associated technical challenges. This presentation includes modelling foundations and simulation results to illustrate how utility-scale electrolysis plants could support a secure and resilient operation of low-carbon grids for both credible and extreme events, and the role of different converter control design setups and operating conditions and constraints.
About the Speaker
Mehdi is an Associate Lecturer at the Electrical and Electronic Engineering Department, The University of Melbourne. He has recently completed his PhD studies in power systems at the University of Melbourne, Australia. His research interests include power system dynamics and stability, system strength, grid integration of renewables and hydrogen technologies, and control of converter-based resources.
Date and Time
The talk was held online on Thursday 18 November 2021 from 5:00pm - 6:00pm Perth time (AWST).
28 September 2021: IEEE PES Presentation on 'Estimation and Modelling Techniques for Real-time Frequency Stability Assessment in Low Inertia Power Systems'
The IEEE PES/PELS WA Chapter organised a talk by Julius Susanto and Alireza Fereidouni.
Many power systems across the world are experiencing a gradual decline in synchronous inertia levels as synchronous generators are increasingly being displaced by generation interfaced to the grid via power-electronic converters. As inertia levels decrease, the average frequency in the power system is subject to more severe and rapid fluctuations in response to active power disturbances, e.g. from generation or load contingencies. It is therefore becoming more crucial that i) estimates of system inertia are reliable and accurate, and ii) frequency stability can be assessed in real-time.
This presentation will describe the models and tools used for inertia estimation and real-time frequency stability assessments in the South West Interconnected System (SWIS), an islanded power system with declining levels of system inertia due to increasing renewable energy penetration.

16 September 2021: IEEE PES Webinar on 'Power systems analysis, open source and the current challenges, the example of GridCal'
The IEEE PES/PELS WA Chapter organised a technical webinar by Santiago Peñate-Vera.
Our need to decarbonise all our production processes requires us, to come up with ways to substitute steady carbon-based generation (coal and gas) by variable renewable generation (wind and solar plus storage). The fast-paced developments required to meet the decarbonisation goals, forces us to shift from a comparably very simple planning process to a far more complex one based on large amounts of data and cutting-edge simulation and optimization methods. This requires researching and to re-invent many of the processes. For that, our best bet is open-source software. This presentation explores some of the current challenges in power system planning and how the use of open-source software provides a solution to many of these problems. Examples of open-source software, particularly GridCal and its evolution are shown to illustrate the concepts presented.
About the Speaker
Santiago is a senior power systems engineer at the planning department of Red Eléctrica de España (Spanish TSO) in Madrid, Spain. Santiago is M.Eng Industrial and Electrical engineer by the university of Las Palmas of Gran Canaria, Spain and MBA by the university of Barcelona, Spain.

19 August 2021: IEEE PES Presentation on 'Electric Vehicles for Sustainable Developments with a European Perspective'
The IEEE PES organised a virtual talk by Professor Lina Bertling Tjernberg.
The energy system is in a global transition towards a sustainable society. Resource efficiency and environmental concerns push towards change into the use of renewable energy resources and to optimize the energy usage. This transition has been motivated by climate and energy goals and a growth in energy needs. The United Nations adapted a resolution for a sustainable development with 16 goals until 2030 and the European Commission has launched the targets towards 2030 of at least 27% renewable energy in final energy consumption at European level. New power grid developments include possibilities and challenges with generation, delivery, and usage of electricity as an integrated part of the energy system. This involves new forms of usage of electricity, for example, for transportation and demand response, and to the updating of existing electricity infrastructures. For electricity generation, the trend is toward new large-scale developments like offshore wind farms, as well as small-scale developments like rooftop solar energy. At the same time digitalization of society is creating new opportunities for control and automation as well as new business models and energy related services. Another key area for developments are the circular economics, which result in a new dimension for the life cycle cost assessment for all technical systems.
This presentation will focus on the introduction of the electrical vehicles (EVs). The EVs both contributes directly to the reduction of fossil fuel but also as a facilitator in the power grid. The presentation will share experience from the developments in Europe. “EV and PHEV sales in Europe continue to break records in 2020 with a 142% increase of deliveries to over 1,36 million registrations of plug-in vehicles, which is 11.4% of the total European car market, more than triple the share of 2019!
