Speech Title: Variable Renewable Energy Technology and Modern Energy Systems

Abstract: Renewable energy applications are in quick development and form a very important part of the Green Transition. It is expected the electricity will be the major format of future energy to meet the demands of the society, and main part of the future electricity would be generated from variable renewable sources, such as wind turbines and solar PV panels, which are fluctuating energy sources, not controllable in sources and connected to the grids though power electronic converters. These variable renewable energy generation units are replacing the traditional fossil fuel based synchronous generator units, this change would significantly change the characteristics of power systems and present many challenges.

The speech will describe the development status of variable renewable power generation technologies, discuss the impacts of power electronic interfaced renewable power plants on power systems, and the possible technical solutions, including some recent research results.

Dr.Bai had presided over the completion of a number of projects funded by national 863 program and National Natural Science Foundation of China. He had ever developed the first 1MWth soldi particel receiver and 1MWth solar air receiver system of China. He had published more than 70 academic papers in journals or proceedings. He had more than 40 authorizated national invention patents. 

Solid particles have good absorption performance in the solar spectral range, and have higher volumetric heat capacity for a variety of solid particles materials, which makes solid particles have potential as heat absorbing and storage materials in solar thermal power generation. Some kinds of solid particles could be used in a wide temperature range up to 1300 ℃. Most of solid particles come from a wide range of sources and are inexpensive. Therefore, the research of solid particle receiver has become one of the hotspots in recent years. In this presentation, theoretical analysis and experimental study on the flow and thermal performance of a solid particle receiver of solid particles free falling insides the quartz tube bundles will be presented. The advantages and disadvantages of this type solid particle receiver are summarized, which can provide reference for subsequent research and receiver design.

Associate Professor Nor Asiah Muhamad

Universiti Teknologi Brunei, Brunei Darussalam

With millions of homes and businesses relying on the National Grid, engineering research in high voltage electrical energy systems is very important in protecting from surges, preventing blackouts, and ensuring safety and efficiency from the grid across. My research interest lies in detecting incipient faults for condition monitoring of electrical power equipment as well as at the transmission system to ensure continuous supply from generation to the end-user. Besides that, I also doing research to find and do the improvement of new insulation material developed for high voltage equipment applications. 

Speech Title:Design of Experiment (DOE) Approach for Optimization of Antioxidants Mixtures for Improvement of Natural Ester Transformer Oil Oxidation Stability and Dielectric Strength Properties

Abstract: Natural ester insulating (NEI)  oils have been developed since the early 1990s due to the increasing  environmental, health and safety concerns from the public. NEI oils are  well-known for having high fire and flash points, good moisture solubility,  biodegradable, non-toxicity and non-corrosive. However, NEI oils also have  several drawbacks compared to mineral insulating oil such as low oxidation  stability, high viscosity, low pour point and low resistance to negative  lightning impulse. Previous researchers have discovered that the oxidation  stability of NEI oils can be improved by the addition of mixed antioxidants,  however the right amount of antioxidants mixtures that improve NEI oils  properties are still unclear. Because of this drawback, this research was  carried out to enhance the oxidation stability together with the dielectric  strength of NEI oil with less influence on other insulating oil properties  whilst improving its performance under simulated real transformer condition.

Speech Title: Power Quality Issues at Industrial Facilities

Abstract: A trend towards nonlinear loads and automation is increasing power quality concerns. In general, power quality issues are not visible on the electricity bill, but they have noticeable effects almost every time. A variety of disturbances can adversely affect the quality of power, including transients, voltage sags, harmonics, flickering, and unbalanced power. In an industrial plant, power quality events can result in loss of production, product damage, and equipment failure. In most industrial facilities, power quality monitoring does not become important until a problem is encountered. This is due to the high cost of monitoring devices and the complexity of detecting, analyzing, and fixing power quality problems. Power quality issues need to be resolved by the plant owner. By using comprehensive knowledge of power quality issues and taking action before incidents occur, it is possible to lower the costs and improve the reliability of their production lines.
