Talk title: Renewable energy sources and smart power systems - minimizing total society cost

Abstract: In Japan, large penetration of distributed generations with RE sources such as photovoltaic (PV) power generations and wind power generations, is going based on government policy which is towards construction of low carbon society aiming at sustainable society. Although these RE sources are free from exhaustion and do not generate greenhouse gas emissions at time of power generation, some of RE sources have a demerit such as output power instability by weather conditions and difficulty of output power forecast. With large penetration of such variable output sources, it will be difficult to maintain supply and demand balance in a total power system. And also, considering RE sources penetrations to customer’s side, it is required to consider new phenomena such as that one way power flow will be changed to both ways power flow, which was not considered in a conventional electric power system’s design philosophy. Due to these backgrounds, to have large integration of RE sources, it is required to make evolution in today’s power systems. They must be changed to smarter power systems, where Information and Communication Technology (ICT) is utilized for cooperation of power apparatus and a total optimization is aimed such as minimizing total society cost. In Japan, challenging Japanese style smart grids has been started aiming at realizing a low carbon society without losing power system’s reliability, economics and resistance to environment.

San Shing Choi

Queensland University of Technology, Brisbane

KeynoteSpeakerBrief bio: S. S. Choi received the B.E. and Ph.D. degrees from the University of Canterbury, Christchurch, New Zealand, in 1973 and 1976, respectively. He subsequently worked in the New Zealand Electricity Department, the National University of Singapore and the State Energy Commission of Western Australia, Perth, Australia. From Oct 1992, he was with the School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore. After relocating to Australia in April 2014, he takes on the position of Adjunct Professor of Curtin University of Technology, Perth and Queensland University of Technology, Brisbane. In this new role, he continues to supervise graduate students and gives research seminars. He is also a visiting professor of several universities, including that of Hohai University, Nanjing, China. His research interests include power system control, renewable energy and energy storage systems. He is the recipient of the IEE Sebastian Z.D. Ferranti Premium for the 1989/90 session, the IEEE Power Engineering Society Surge Protective Devices Committee High Interest Paper Award 2004 and the Best Paper Award of the 2011 IEEE Conference on Innovative Smart Grid Technologies Asia, ISGT, Perth, Australia.

Talk title: Energy Storage: A Necessity for Power Systems Containing Significant Level of Renewable Generation

Abstract: An overview of the motivating factors for renewable generation is given. The roles energy storage systems can assume in this new paradigm of power systems are then explained. Several examples of the application of energy storage technology in grid systems are presented, wherein the objective is either to achieve power bridging, power quality enhancement or renewable power dispatchability. Li-ion battery can be a prime energy storage candidate to help achieve these objectives, particularly operating in conjunction with renewable distributed generators under a micro-grid environment. As suitable battery models are essential for the design and planning of the battery systems in such applications, the development of a Li-ion battery equivalent circuit model is also described. The model can provide certain insights into the internal states of the battery and is amenable for inclusion into the real-time power/energy management system of Li-ion battery banks.

Talk title: Novel Motor Drive Technologies for Permanent Magnet Synchronous Motors

Abstract: Motors consume about 60 % of the electricity consumed by electric apparatus. Hence, high efficiency motors, permanent magnet synchronous motors (PMSMs) need to be made more widely available. Therefore, a rotor position sensorless control is one of the key technologies to make PMSMs widely available. Furthermore, the rotation speed of PMSMs tends to become high due to downsizing and low cost. The speed range of the motors has been extremely extended. As a result, recent PMSMs have a wide variety of characteristics including the nonlinear characteristics. On the other hand, the motor drive technologies have been greatly developing to control these recent motors freely. In this talk, I will present several drive technologies for a wide speed range, a high efficiency and nonlinear characteristics.
