Power electronics based energy systems: challenges and opportunities

 

Abstract: Modern electricity network is undergoing a significant transformation with an aim to achieve a sustainable and convenient system through the uptake of alternative energy sources and energy storage systems and more intelligent approach to configuring and managing the network. Power electronics technology plays a key role in integrating the new energy sources and managing the network effectively and efficiently. Power electronics based energy system performs power conversion through different converter topologies and flexible control techniques. With many opportunities arise from the transformation, these power electronics systems are also facing a lot of challenges, such as reliability of internal devices and circuits, energy balancing of battery cells, efficient power point tracking and power conversion for a wide operating range, stability among interconnected modules and power quality issues of the network.  In this talk I will discuss some of these aforementioned challenges and how we can use suitable converter topologies and modified controllers to improve the power electronics systems for building and operating sustainable energy systems.

One the Simulation of a Complex Power System

 

Abstract: A complex power system consists of a variety of electrical components, including generators, transmission lines, transformers, loads, battery storage systems, and power electronics devices. In this presentation, the development of a mathematical model and a computer simulation framework for a complex power system will be discussed. Moreover, the knowledge of internal dynamic states of power generators has shown increasing importance in achieving better control performances in power systems. Due to the hardship of direct measurements, dynamic state estimation methods are employed to obtain the internal states needed for controller designs. Based on the simulation model, the general procedure of utilizing contemporary estimation techniques to acquire the internal dynamic states of generators connected electric grids will also be discussed.

Utilisation of emerging technologies to help sustainably manage issues in rural electricity networks

 

Abstract: Predominantly towards the end of long, radial, MV feeders and with a relatively small density of customers, utilities have found the costs associated with traditional network renewal and upgrades to meet the electricity needs of “high cost to serve” communities increasingly challenging.   However, via the use of computer aided network optimisation algorithms, energy storage, micro-grids and associated enabling technologies, cost effective and sustainable alternative solutions are increasingly becoming possible.     Shervin will present case studies outlining Western Power strategies and projects developed to address challenges in supplying communities at the fringes of the distribution network.  

 

 

Shervin Fani - is a Chartered Professional Engineer with a Bachelor of Engineering from The University of Western Australia.   After graduating in 2003 with a double major in Electrical and Electronics Engineering he spent the early parts of his career in the Communications and SCADA fields, later transitioning to the Electrical dripline where he has been actively practicing for over the last 10 years.   In that time, Shervin has been engaged in a variety of electricity distribution and transmission engineering roles, including power systems planning, standards, protection, maintenance and design.   Having previously held Team Lead and Management positions at Western Power, he is currently employed by the organisation as a Principal Engineer advising on emerging technologies, alternative energy business models and sustainable network development.  As part of his extracurricular activities, Shervin sits on the CIGRE Australia C.6 working group focusing on Distribution Systems & Dispersed Generation.  He is a member Engineers Without Borders, currently leading a joint U.N. / EWB research project investigating off grid power supply for refugee camps.  He also acts as an industry supervisor for postgraduate engineering student’s thesis projects.

Wireless Grid Integration of Electric Vehicles for V2G applications

 

Abstract: Global concerns relating to air-quality, carbon emissions, inefficient transport and depleting fossil reserves are further exacerbated by the rapidly escalating number of vehicles on roads around the world. Amongst numerous efficient and clean vehicle technologies and alternative fuel sources that have been proposed to address these concerns, electric vehicles (EVs) are gaining wider acceptance as the way of the future. This is primarily because EVs are increasingly perceived as the most promising technology for sustainable living with the potential for improving air quality and energy security with demand control using the vehicle to grid (V2G) concept. However, EV technology has its own challenges, particularly in relation to developing an efficient, compact and reliable power interface for both charging and discharging. For this reason, grid integration of EVs and its impact on the grid have become a main focus of current research in both industrial and academic communities. EVs can be charged by wired or wireless means, and the latter, based primarily on wireless power transfer (WPT) technology, is becoming increasingly popular, being convenient, safe, and ideal for both stationary and dynamic (while moving) charging of EVs.

 

Biography: Udaya K. Madawala (Senior Member IEEE) graduated with B. Sc. (Electrical Engineering) (Hons) from The University of Moratuwa, Sri Lanka in 1987 and received his PhD (Power Electronics) from The University of Auckland, New Zealand in 1993 as a Commonwealth Doctoral Scholar. At the completion of his PhD, he was employed by Fisher & Paykel Ltd, New Zealand, as a Research and Development Engineer to develop new technologies for motor drives in washing machines. In 1997, he joined the Department of Electrical and Computer Engineering at The University of Auckland as a Research Fellow. At present, as a Full Professor, he focuses on a number of projects related to renewable energy and wireless grid integration of EVs with bi-directional power flow.


Professor Madawala has over 28 years of both industry and research experience in the fields of power electronics and magnetics. As an IEEE member, he currently serves as an Associate Editor for IEEE Transactions on Industrial Electronics and IEEE Transactions on Power Electronics, and is a member of the Power Electronics Technical Committee and Renewable Energy Committee of IEEE Industrial Electronic Society and Power Electronics Society, respectively. He has over 250 international journal and conference publications, and holds a number of patents on inductive (wireless) power transfer and power converters with several pending. His research interests are in the fields of renewable energy, power electronics and inductive (wireless) power transfer, for which he offers his service as a consultant to industry.

Supercapacitors with high energy density

 

Abstract: Supercapacitors have attracted great attention as potential energy storage devices. Comparing with batteries, supercapacitors can much more quickly be charged. However,their energy densities are much smaller. This talk will focus on the fabrication and properties of some supercapacitors with high energy densities.
