WELCOME

Dear All

As General Chairman and on behalf of the organizing committee, I warmly welcome you

to attend the 6th IEEE Southern Power Electronics Conference (SPEC 2021) which was to be held in hybrid form with virtual and in-person attendees at Kigali Marriott Hotel, Kigali, Rwanda, from 6-9 December 2021. However due to the continuing COVID-19 pandemic

the conference will now be held in fully virtual form.

SPEC was founded and sponsored by the Power Electronics Society (PELs) of the Institute of Electrical and Electronic Engineering (IEEE), with the view to promote Power Electronics

and its applications in the Southern Hemisphere, where resources and opportunities to network, share ideas and establish collaborations among members are somewhat limited. SPEC has never been held in Africa and, hence, it is high time that the conference is held

in an African country. Rwanda is arguably the safest country in and Kigali the cleanest city in Africa and the weather is pleasantly warm throughout the year. SPEC 2021 in Rwanda

is, therefore, an ideal opportunity for students, researchers, engineers and academics from all over the world to bring the latest technological advances and applications in Power Electronics to the Southern Hemisphere, and to the African continent to promote the

discipline. World-renowned scholars will deliver keynote and plenary speeches as well as conduct tutorials on topics of global interest. A wide range of technical sessions is also

included in the conference program for participants to make contributions towards advances within the field of power electronics.

Rwanda is a country known for its breath-taking scenery and is often referred to as the land of a thousand hills. View the virtual tour of Rwanda to appreciate the beauty of this

country. The organizing committee will ensure that your participation in SPEC 2021 is productive and your visit to Kigali is a memorable experience.

I look forward to welcoming you at SPEC 2021.

Yours sincerely

Sarath B Tennakoon

General Chair IEEE SPEC 2021

Electric Vehicle Technology Advances

Electric and hybrid vehicles have developed greatly in recent years with most major manufacturers offering electric versions of vehicles across

their range. They are torque and power dense and often rely on fluid cooling to deliver high transient performance during acceleration and

regenerative braking. Most are brushless permanent magnet synchronous machines though other machines, such as the induction machine, are used. This presentation will

review the current state-of-the-art for vehicle drive machines and highlight the key characteristics that are required. With their development comes new analysis techniques

which will also be addressed. Future developments will be discussed. Particularly two-wheeled scooters and motorcycles. These are now common in countries such as China

and may offer a solution to the developing world as a form of cheap and economical transport. In addition, a lot of Africa uses taxis (which are 16-seater minibuses) and there

are plans to develop these for the continent. This talk will present a short historical perspective of how the HVDC and FACTS industry got to its present position, a description

of the present state of the art and predictions of how the grid will evolve in the coming decades.

Current Trends and Future Strategies for Air Transportation

The aerospace industry is facing challenges similar to the automotive industry in terms of improving fuel economy and reducing the emissions and cost. The air

transportation accounts for about 2.5% of global CO2 emissions. In order to reduce the emissions from the aircraft, the industry has seen an increasing research

and technology advancements in more electric aircraft (MEA), electric, and hybrid electric aircrafts. In addition, in order to reduce the traffic congestion and

improve the urban air quality, a number of companies are developing short range electrical vertical take-off and landing vehicles (eVTOL) and flying cars, which

can be used as air taxis or for personal transportation. In MEA, the intent is to move as many aircraft loads as possible to electrical power, resulting in simpler aircraft systems leading to the

potential for lower fuel consumption, reduced emissions, reduced maintenance, and possibly lower costs. The electric aircraft and hybrid electric aircrafts will further reduce the emissions,

improve the efficiency, and provides better controllability for the aircrafts. The advancement of flying cars and eVTOL vehicles is reshaping the future of transportation. In this presentation, the

current trends and future strategies in aircraft propulsion to reduce the emissions and a brief overview of how the power electronics technology is enabling to develop the next generation of air

transportation will be presented.

FACTS and DC transmission: History, State of the Art and Future Developments

From the very earliest days of electrical power transmission, in the 1880s, the advantages of DC (as promoted by Thomas Edison) were already

clear but despite this, the “Battle of the Currents” was won by Westinghouse and Tesla’s AC solution, mainly because two 19th century

inventions, the transformer and the circuit-breaker, were much easier to realise using AC than DC. Nevertheless, the use of DC in certain, niche

point-to-point transmission applications never completely went away, with the first electromechanical conversion systems installed in the

1890s and electronic AC/DC conversion starting to appear in the 1930s. Today, HVDC is widely used for point-to-point power transmission

applications where very high powers need to be transmitted for long distances, and the first commercial applications of meshed HVDC grids and medium-voltage DC (MVDC)

for reinforcement of distribution grids, are starting to appear. With the drive for ever-increasing levels of renewable energy generation, along with drastic changes in

consumption patterns as transportation and domestic heating are electrified, much greater use of DC for both transmission and distribution are inevitable. At the same time,

limitations of “traditional” AC power systems led to the introduction of “Flexible AC Transmission Systems” (FACTS), a set of technologies that are complementary to those

used in DC transmission systems. Since the AC power grid is unlikely ever to disappear completely, FACTS remains more important today than it ever has been, with new

technologies such as the Unified Power Flow Controller starting to gain a foothold alongside more well-established technologies such as SVCs and series capacitors.

This talk will present a short historical perspective of how the HVDC and FACTS industry got to its present position, a description of the present state of the art and predictions

of how the grid will evolve in the coming decades.

Advanced Signal Processing, AIs and Machine Learning in Condition Monitoring,

Prognostic and Diagnostic of Power Electronic Converters and Batteries

Renewable energy systems, modern grid, transportation electrification, and other applications, all depends heavily on Power Electronic

converters and Batteries. Degradation, aging, mechanical stresses, temperature changes, all contribute to shorter system lifespans and more

failures. To address these issues, several advanced condition monitoring techniques have recently been developed. However, there are several fundamental challenges in

condition monitoring and health diagnostics of power electronic converters and batteries. These are related to suitability for online and real-time implementation,

implementation cost, aptitude to deal with abrupt real-time changes, reducing the effect on the power converter outputs, estimation/prediction accuracy, computation

complexity of the proposed algorithms, and so on. Advanced signal processing, AIs, and ML techniques have been found to provide superior solutions for addressing the

aforementioned issues with fast dynamic performance, cost-effective, high accuracy modelling and estimation, good tracking ability to system changes, health monitoring,

and fault detection. This talk highlights our recent advances in adaptive control techniques, AIs, ML, system dentification and parameter estimation algorithms for condition

monitoring and control of power electronic converters and batteries.

Tutorials

Monday 6th December | 9.00 am-12.00 pm (GMT + 2)

Tutorial 1 – Grid Forming Inverters: A Control Design Overview

Dr. Behrooz Bahrani and Dr. Mohammad Hasan Ravanji, Grid Innovation Hub, Monash University, Australia

Electric power systems are increasingly being augmented with inverter-based resources (IBRs). While having a growing share of IBRs, conventional synchronous generator-based

voltage and frequency control mechanisms are still prevalent in the power industry. Therefore, IBRs are experiencing a growing demand for mimicking the behavior of synchronous

generators, which is not possible with conventional grid following inverters (GFLIs). As a solution, the concept of GFMIs is currently emerging, which is drawing increased attention

from academia and the industry. GFMIs were primarily developed to establish voltage and frequency in islanded microgrids. However, owing to their capabilities, they can be

employed as a promising solution for providing power system services via IBRs. In this tutorial, different control approaches for GFMIs are discussed in detail. In this regard, first, the

inner control loops, including the pulse-width modulator, current control loop and voltage control loop, are described. Then, various primary controllers employed to provide

frequency services for the system, including droop controller, filtered droop controller and virtual synchronous generator (VSG) control are introduced and elaborated. Recently

commissioned projects in Australia, the UK, and the US are taken as examples to highlight the trend in the power industry in adding GFMIs to address issues related to weak grid

scenarios. Research directions in terms of voltage control, frequency control and system strength improvement are also discussed. This tutorial is intended for researchers and power

system engineers exploring solutions to the emerging problems with high penetration of IBRs, focusing on GFMIs.

Tutorial 2 – Lightning Protection of PV Energy Systems: The Scientific Approach

Prof. Chandima Gomes, University of the Witwatersrand, Johannesburg, South Africa

In the last decade, as photovoltaic energy systems rapidly spread over the world, lightning protection of not only them but of all other connected systems has also become a prime

concern of the engineering community. The rapid sophistication of many units of a PV system (eg. inverters replaced by micro-inverters) made them more vulnerable to lightning

effects and consequently became a continuous challenge for protection designers. Unfortunately, in many developing countries, due to various financial constraints and too

aggressive marketing strategies, lightning protection is fundamentally neglected either due to ignorance or concerns of cost reduction. However, in the last few years, the statistics

from Malaysia, India, South Africa etc., show that the overlooking of lightning protection, in the first place, has cost many PV owners, many millions of dollars in the form of complete

destruction of PV systems (due to fire and explosion), equipment damage and degradation, service interruption and downtime. Most often local PV system owners and even local

vendors seek lightning protection after encountering the first or second lightning-related adverse effect. In many African countries, except South Africa, the knowledge and skills of

lightning protection are scarce, thus, it is time-consuming and expensive to import the technology. Therefore, it should be a prime concern of the engineering statutory bodies in

each country to develop lightning protection as entrepreneurship at various business scales. Lightning protection could be divided into two inter-dependent segments; structural

protection and surge protection. The first deals with protecting the buildings and any other physical structures from lightning direct strikes or side flashes. The second covers the

engineering of safeguarding equipment and power/signal networks. Both need a risk assessment to select the most cost-effective lightning protection measures before designing the

protection system. Grounding and bonding also plays a vital role in both structural and surge protection. Although, there is a comprehensive set of standards available for general

lightning protection, the guidelines for safeguarding renewable energy sources, such as PV systems are yet to be fully developed. Developing countries in the tropics encounters an

additional challenge of assessing the risk under much intense lightning ground flash density compared with that in most developed countries. A higher risk demands more robust

protection measures, which in turn enhance the cost of protection. Under these circumstances, it is of prime importance for each country in regions of high lightning flash rates to

develop its internal engineering knowledge base and skilled workforce in this field. It is also advisable to extend these efforts to develop the lightning protection component

manufacturing industry as well.

Tutorial 3 – Multi-phase Induction Machines & Multi-phase Inverters (Topologies, Control and

Applications)

Prof. Kouzou Abdellah, Head of Power Electronics and Power Quality Group, Djelfa University Algeria

Dr. Jaroslaw Guzinski, Gdansk University of Technology, Poland

Prof. Mokrani Lakhdar, Laghouat University, Algeria

Multiphase induction machines and multi-phase inverters are attracting an increasing attention due to their inherent advantages over three-phase machines, e.g. reduced per phase

power rating, improved reliability and increased degrees of freedom. Compared with their counterparts of three phase Induction machines and three-phase inverter, variable speed

multiphase induction machine supplied by multi-phase inverters provide a higher power range by utilizing low-power switching devices, due to the higher number of inverter phase

legs and higher torque density. These properties are in particular important for many applications in which the power supply voltage is limited, the torque oscillation amplitude is

required to be decreased and the fault tolerant ability is required. Indeed, the fault-tolerance capability is one of the most crucial attractive properties of multiphase machines and

multi-phase inverters for almost recent and innovative industrial technologies and applications. Especially, for drive systems with high reliability in non-stop operation conditions,

which are known for high economical and safety repercussions caused by fault occurrence, e.g. in electrical vehicles, traction, ship propulsion, and other safety-critical applications

such as electrical helicopters. The tutorial will deliver the base knowledge on multiphase induction motor drives and Multiphase inverters. The mathematical model, exemplary motor

constructions, drive control methods including speed sensorless control, multi-phase voltage inverter control and furthermore the operation in faulty states will be shown. It is to

note that may be simulation examples will be checked with attendees. So the only requirements that the attendees need to have their PCs with MATLAB software.

Tutorial 4 – Modelling and Control of Active Front End Power Converter Connected to Weak and

Asymmetric Networks

Dr. Daniel Siemaszko, Power Electronics and Systems Consultancy, Switzerland

This tutorial aims to give both intuitive and practical understanding on the issues related to the control of Voltage Source Inverters connected to any kind of grids in a general

context of multiplication of decentralized power generation and microgrids. A special focus is provided to weak or isolated networks with a particular attention to synchronization

and harmonics. The implementation of dedicated control on the power converter side together with a careful identification of network perturbations is subject to design and

simulation examples supported by industrial experience and academic approach. The covered topics include network basics (grid modelling, strength, harmonic distortion and

standards), control of power converters (control basics, handling of AC systems), grid synchronization (PLL techniques, handling of weak networks with disturbances) and handling

of asymmetric grids (control techniques for decoupling disturbances).

The Tutorial will be composed half/half with traditional slides and practical demonstrations that the audience can follow and redo on their own computers. Both aspects will allow

interactive discussions and parameter modelling. The models are built and demonstrated with Simba, a simple and powerful simulation environment that is free for academics and

that allows Python automated scripting. The audience should have a computer and possibly an installation of the modelling software that can be found on Simba.io (free for

academics, trail version for industrials). The audience should have some basic knowledge in control of power electronics converters and grid connected power systems. The topics

will first cover introductory aspects suiting the non-specialists, followed by some advanced features suiting the specialists.

Tutorial 5 – Integrated Power Electronics and Machine Learning Solutions for Health-conscious Battery

Management Systems and Fast Charging Applications

Prof. Sheldon Williamson, Canada Research Chair in Electric Energy Storage Systems for Transportation Electrification, Ontario Tech University, Canada

Enhancing the life of Lithium-ion (Li-ion) batteries has been the topic of much interest in the e-transportation industry. In this framework, the role of on-board cell voltage balancing

(with temperature rise) will be presented. This is a critical design aspect, which affects cost, calendar life, state-of-charge, and state-of-health. The design and implementation of

novel DC/DC converters for battery cell-voltage-equalization will be discussed. For the first time ever, this seminar will also introduce a closed-loop cell-charge-balancing technique

that uses instantaneous cell voltage and temperature rise (ΔT) as control parameters. This presentation will go on to cover the design and development of a customized automated

battery system (ABS), which was built to automate the overall testing conditions and reduce human error. Finally, the seminar will cover the all-important topic of temperature-

and health-dependent battery cell modeling, characterization, and cycle life estimation. This part of the talk will include smart core and surface temperature estimation techniques

for health-conscious BMS and will present a model-to-model comparison. A comprehensive review of cell temperature estimation techniques applicable to health-conscious fast

charging and smart BMS will also be presented. Finally, a critical review of machine learning-based data-driven fault detection/diagnosis of lithium-ion battery will also be presented.

Tutorial 6 – Challenges of Integrating Renewable Generation to Power Grids and the Relevance of EMT

Studies

Dr. Dharshana Muthumuni, Managing Director, Power Systems Technology Centre, Manitoba Hydro International, Winnipeg, Canada

Electromagnetic Transient (EMT) simulation plays an important role during integration of wind and other renewable energy-based generation to transmission networks. This is mostly

in view of the fact that renewable generation is connected to grids through power electronic inverters.

A number of dynamic response issues are identified when inverter-based generation is connected to ‘weak’ (low short circuit levels) locations of transmission network.

● The voltage (specially the phase angle) at weak grid locations shows pronounced variations following a system disturbance such as fault clearing. The inverter response is

critically dependent on measuring such phase angle changes (instantaneous response as opposed to rms) accurately through the Phase Locked Loop (PLL) and other signal

measurements at the connection point. Inability of PLL to correctly track the voltage changes has resulted on poor fault recover response of the inverter or tripping of the

unit in violation of grid codes.

● The voltage control at weak locations is challenging. When multiple inverter-based devices are located in close vicinity in a weak grid area, there is a risk of these fast acting

(fast reactive current control) devices interacting in an unstable manner and leading to a multitude of issues, generally classified as ‘control interaction’.

● Key technical issues will be discussed through a technical presentation and PSCAD case studies will be presented to highlight specific concerns. Best practices to follow
