Plenary Lecture: MicroGrid Designer：User-Friendly Design, Operation and Control Assist Tools for Resilient Microgrid and Autonomous Community

Abstract: In this decade, many countries experienced natural and accidental disasters such as typhoons, floods, earthquakes, and nuclear plant accidents causing catastrophic damage to infrastructures. Since the end of 2019, all the countries in the world are struggling in the Corona Virus and pursuing the countermeasures including inoculation of vaccine and change of our life style and social structures. All these experiences made the residents in the regions keenly aware of the needs for new infrastructures that are resilient and autonomous so that vital life-lines are secured in calamities. A paradigm shift has been taking place toward reorganizing the energy social service management in many countries including Japan by effective use of sustainable energy and new supply schemes. However, such new power sources and supply schemes would affect the power grid through intermittency of power output and the deterioration of power quality and service. Therefore, new social infrastructures and novel management systems to supply energy and social service would be required. In this paper, user-friendly design, operation and control assist tools for Resilient Microgrid and Autonomous Community are proposed and applied to a standard microgrid to verify its effectiveness and performance.

Prof. Jinjun Liu (IEEE Fellow)
Xi’an Jiaotong University, China

Keynote Lecture: Modeling and Control Design of High-Bandwidth Buck Converters

Abstract: High-bandwidth control of DC-DC converters can further improve the dynamic response of systems and reduce the size and cost of power regulation modules when the switching frequency of power semiconductor devices has reached an upper limit due to the restriction from thermal management capability on power losses in specific application. High-frequency modeling is therefore an important theoretical basis for analyzing and designing high-bandwidth DC-DC converters, while there are many shortcomings and disadvantages with past modeling methods. This presentation summaries the state-of-arts work regarding the modeling of high-bandwidth Buck converters under three typical control methods, i.e., constant-frequency average voltage mode control, constant-frequency peak current mode control and constant on-time current mode control. It turns out that, after careful and quantitative handling of the equivalent spectrum extension effect of the modulator, the influence of the switching ripple, and the coupling of the sideband component with the main-band component, corresponding high-frequency analytical models can be obtained with both satisfactory accuracy as well as appropriate simplicity. Based on these models, design methods of high-bandwidth controllers are also proposed and illustrated in details.
