附:1. Robust Control of Power Electronics in Power Systems(桂勇浩博士)

内容摘要:Recently, due to the rapid development of smart grid, flexible AC transmission systems (FACTS), high-voltage direct current (HVDC) systems, and renewable energy sources (wind, photovoltaic, and fuel cells, etc.), there has been a tremendous increase in the use of power converter (power-electronic converter) systems. In this talk, I will focus the works about control of power converters what I have done at Aalborg University.

At first, I will introduce a novel direct power control method called grid voltage modulated direct power control (GVM-DPC) strategy for a grid-connected voltage source converter. The main advantage is that the GVM-DPC method makes the system be a linear time-invariant system, which enables us to apply various control methods easily.  Secondly, I will present a voltage modulated direct power control (VM-DPC) for three-phase pulse-width modulated rectifier system. With the suggested method, the differential equations describing the rectifier dynamics are changing from a linear time-varying system into a linear time-invariant one.  Then, a novel coordinated control applied to renewable energy source (RES) and energy storage system (ESS) units will be introduced in islanded microgrids without using a phase-locked loop (PLL) system. Lastly, a weak grid connected voltage source inverter is controlled to overcome stability problem caused by PLL.

2. Waste heat recovery of internal combustion engine(梁友才博士)

内容摘要:The thermal efficiency of internal combustion engine accounts for 35-45% only and the rest of the input energy is discharged in the atmosphere in terms of exhaust and jacket water as “waste heat”. Therefore, Waste heat recovery (WHR) has been taken as the most potential technology to make more efficient usage from fuels to achieve environmental improvements. In the first part, I will introduce different heat recovery technologies for different applications. Combined cycle for cascade utilization will be presented in the second part. Although the waste heat recovery of engine has evolved to become a mature technology over the past two decades, it is not applied as widely as it should be. The main challenge is downsize of the system due to the economy issue, especially for the internal engine onboard. Therefore, the state of the art of heat transfer enhancement technologies will be introduced in the third part.

3.Nature-inspired slippery surface design for fluid manipulation (郝崇磊博士)

内容摘要Bioinspired topological mechanical surface science and engineering based on micro-nano processing is a hot topic in current scientific research and engineering applications, involving mechanical engineering, engineering thermophysics, materials, energy and other disciplines, and belongs to the multidisciplinary research fields. For aerospace, energy equipment and the environment, the development of nature-inspired new materials for interface drag reduction, self-cleaning / anti-fouling, heat transfer enhancement and anti-icing has become an important research direction. At present, the related study mostly focuses on the static behavior analysis of the bioinspired interface, and the material development is mostly limited to the manipulation of traditional solid materials such as metal. In practice, many applications involve the dynamic behavior of droplets or liquids on the surface, especially how to accelerate the detachment of liquid from the surface. However, the surface of liquids in traditional solid structures is often limited by the pinning effect of three-phase contact lines. How to break through conventional design theories and manufacturing methods, and to establish new theories and material systems have important scientific and engineering significance. This report will introduce our research work in the field of bioinspired fluid interface, especially in the scientific breakthrough in the fundamental research of droplet microscopic dynamic behavior, and development of a new micro/nano structured liquid-liquid bioinspired interface, providing important insights for applications such as drag reduction, energy harvesting, lens imaging, and enhanced heat transfer.
