Title: Power Energy Management in Microgrid
Abstract: The aggravation of global energy crisis has increased the attention for the study of energy efficiency and energy economical by integrating high penetration of renewable energy sources (RES) into the distribution grid network. The microgrid is considered as a future power system network which benefits to the flexibility and reliability of electricity supply as compared to legacy existing conventional power system, which is centralized and unidirectional energy flows. The autonomous and plug-and-play are the leading features for microgrid, which operates in the mode of isolating from the utility grid. This minimizes the dependable to the utility grid and manageable. However, in isolation mode, RES poses great technical challenges for producing a constant power due to the intermittent in the input source. The microgrid needs to maintain the power to balance the demands. Due to low inertia from the microgrid energy sources, uncertainties and unbalances between distributed generation (DG) and load demand would affect severe power imbalances, voltage instability, and grid frequency fluctuation and eventually make the microgrid breakdown. A power energy management control (PEMC) system is a crucial part of the microgrid. Based on the PEMC approaches, the objectives including managing the power flow, intermittent of DGs, resynchronization response to the operating mode, coordinate the microgrid components and operation cost minimization. Up to date, the effort of improving energy management has become widely investigated in order to achieve the optimize energy flow operation in the microgrid. Therefore, this speech wills presenting problem encountered in microgrid and revision of the PEMC as a review in isolated microgrid environment.

Title: Energy Harvesting System for Internet of Things

Abstract: In the 21st century, the design of efficient renewable energy harvesting system is the most important technological challenge due to the increase in global warming and other environmental issues. The advantage of using energy harvesting in WSN nodes is that it reduces the human efforts required to replace the battery of hundreds or thousands of sensor nodes by going out into remote areas for volcano monitoring, glacier monitoring, forest monitoring and battlefield monitoring applications. The energy harvesting enabled WSN nodes increases the overall sensor network operation lifetime. The Wireless Sensor Networks (WSN) are the basic building blocks of today’s modern internet of Things (IoT) infrastructure in smart buildings, smart parking, and smart cities. The WSN nodes suffer from a major design constraint in that their battery energy is limited and can only work for a few days depending upon the duty cycle of operation. The main contribution of this proposal is to propose an efficient solar energy harvesting solution to the limited battery energy problem of WSN nodes by utilizing ambient solar photovoltaic energy. The WSN node is powered by ambient solar photovoltaic (PV) energy and can measure the temperature, light, humidity, and pressure simultaneously. Then, it sends the measured data to the remote WSN node wirelessly using Zigbee wireless communication protocol.

Title: Sliding mode control with the quick reaching law and its application

Abstract: In order to overcome the disadvantages of the conventional sliding mode reaching law, such as the large chattering, the slow convergence rate, an improved quick reaching law is proposed. The reaching law is composed of two terms which can respectively play the leading role when the system is far away from or near to the sliding mode surface. Thus, the system can arrive at the sliding mode surface with the faster convergence rate from beginning to end. Some other advantages of the reaching law, such as converging to the sliding mode surface in a finite-time, and the second-order sliding mode characteristic, are proved. Furthermore, in order to speed up the convergence rate to the equilibrium point along the sliding mode surface, the global terminal sliding mode control based on the quick reaching law is designed. It is used to control the unmanned surface vehicle. Simulation results show that the control method has better control performance than the conventional methods.

Title: Power Electronic Contributions in Renewable Energy Conversion toward Reducing Global Warming

Abstract: Global energy consumption is increasing at a dramatic rate and most of the energy comes from fossil fuels which cause the problem of global warming due to the emission of greenhouse gases. Climate change and the global warming challenges turn up to be like a major threat to the world. Accordingly, the world is going through a crucial energy problem to supply efficient and cost-effective energy to face the rapid rise of energy need and increasing negative environmental impacts. Therefore, new guidelines and technological innovation are necessary to ensure energy security without causing emissions. Power electronics technology offers high reliability, efficiency and has been successfully implemented in different applications to convert renewable energy, conserve energy, improve performance efficiency and mitigate global emissions. This keynote focuses on various aspects of power electronics technologies in converting energy from convention form to a sustainable form which in turn solves the existing global warming problem. The different topologies of power electronics converters are explained on the basis of types, control difficulties, benefits, and drawbacks. Different categories of power electronics controllers utilized for energy conversion are comprehensively reviewed on their structure, algorithm, and mathematical model, strength, and weakness. Furthermore, the review emphasizes the execution of power converters and controllers in different applications and highlights their contribution to save energy and mitigate emissions. All the highlighted insights of this keynote will hopefully lead to increasing efforts towards the development of the advanced power electronics converters and controllers for efficient energy conversion which in turn can reducing of global warming.

Title: The wear characteristics of wet clutch in the DSG vehicle in a 10km driving cycle

Abstract: In order to investigate the wear characteristics of wet clutches in the DSG vehicle during shift process, this paper presents a dynamic analytical model and an experimental test of wet friction pair for simulation and analysis. A detailed dynamic model is established firstly to calculate the dynamic load of the clutches during the shift process of the DSG vehicle. The wet friction pair experiment is conducted to explore the wear behaviours under different conditions. Then, the wear coefficient is deduced according to the Archard law. The experimental results indicate that, when the temperature is constant, the slipping speed has little influence on the wear coefficient, while the contact pressure is on the contrary. Then, an empirical formula is obtained to describe the relationship between the wear coefficient and the contact pressure. Based on the simulation results, the wear amount of the clutches fixed on the input shaft is about 0.8mg, while for clutches on the middle shaft, it is only 0.2mg within a 10km driving cycle.
