Keynote SpeechesEmerging Technologies in Power Grid Control and Distributed Energy Storage Systems
Prof. Alireza Bakhshai Abstract: Harvesting energy from renewable energy sources (RESs) is essential in future power systems mainly due to the environmental concerns and sustainability. Despite several advantages coming with the use of RESs, there are still many challenges that need to be addressed for efficient use of them when integrated in the power grid. Some of the main challenges regarding this integration are: reliability and robustness, controllability, and cost-effectiveness. A microgrid can integrate large amount of renewable generation into the bulk power system, and make the power system more reliable, secure, clean and economic. The microgrid control system plays a crucial role in the successful implementation of the future power grids. This talk addresses the most challenging issues in microgrid and future smart grid control and presents emerging technologies to overcome these challenges. The talk starts by presenting an introduction to the microgrid technology, and then reviews its control trends. Then, as the most comprehensive control scheme presented so far, the hierarchical control systems will be reviewed, and the speaker’s current research on this topic will be discussed, and a case study will be considered. Biography: Prof. Alireza Bakhshai is with the Department of Electrical and Computer Engineering at Queen’s University. Dr. Bakhshai received his BSc and MSc from the Isfahan University of Technology, Iran, in 1984 and 1986, respectively, and his PhD from Concordia University in 1997. From 1998 to 2004, he served on the faculty of Electrical and Computer Engineering at Isfahan University of Technology. __________________________________________________________
Design of Power Electronic Converters: Beyond Topology
Prof. Jean-Luc Schanen Abstract: Very often, designing a power converter starts choosing a suitable topology, and the associated control strategy. However, the job of the engineer is far from being finished after this step: all components have to be designed/chosen based on the constraints defined by the converter topology, and specific other requirements have to be fullfilled, as ElectroMagnetic Compatibility Standards. At the end of the day, a promising topology may be not so attractive after this technological design. In this presentation, a global methodology based on the "design by optimization" concept will be illustrated in order to facilitate the technological choices offered to the designer for obtaining the best solution at converter level, which will not necessarily result from the best design of individual components. Biography: Prof. Jean-Luc Schanen obtained his PHD in January 1994, from University of Grenoble Alps. He is Professor at Grenoble Institute of Technology since 2003, and is currently leading the Power Electronics Research group. He is also deputy director of the Engineering school Energy, Water and Environment. __________________________________________________________ New Configurations of Power Converters for Grid Interconnection of Renewable Energy Systems
Dr. Marco Rivera Abstract: According the National Energy Strategy proposed by the Chilean Government in March 2012, the growing technological development in Chile has led to the search of energy efficiency and the penetration of the renewable energies and other generation systems to the electricity supply network. The power converters play an important role for the management of electric energy, providing the interconnection between the generation and the distribution systems. The power converters commonly used today include energy storage elements that add weight, size and failure possibilities. The matrix converters do not have energy storage elements and they are a flexible and efficient alternative to manage energy. These converters have been considered in specific applications such as military, aerospace, wind generation systems among others. However, they have not been deeply studied in applications for grid interconnection of generation systems and/or loads. It is expected that their features: 1) compact and simple power circuit without energy storage elements; 2) bidirectional flow capacity; 3) generation of high quality voltages with arbitrary amplitude and frequency; 4) sinusoidal currents generation; 5) operation possibilities with unitary displacement power factor, allow for more robust systems, with smaller size and better performance than traditional configurations. The main objective of this presentation is to propose power converter configurations to allow the grid interconnection of different types of generation systems and/or loads with a cheap, clean and sustainable transmission and distribution structure for the country. Biography: Dr. Marco Rivera was born in Talca, Chile, in 1982. He received the B.Sc. degree in electronics engineering and the M.Sc. degree in electrical engineering from the Universidad de Concepción, Concepción, Chile, in 2007 and 2008, respectively, and the Ph.D. degree from the Department of Electronics Engineering, Universidad Técnica Federico Santa María, Valparaíso, Chile, in 2011. | ||
