Title of speech: Real-time measurement for carbon emissions

Abstract: Reliable and fast calculation of carbon emissions is an important task in achieving emission reduction against climate change. This talk presents an innovative real-time computational framework designed specifically for swiftly assessing carbon emissions originating from industrial load centres. Leveraging non-intrusive load monitoring (NILM) together with real-time smart meter data, this framework offers a robust solution for efficiently quantifying emissions within industrial settings. Through NILEM we can gain invaluable insights into the intricate energy consumption patterns of industrial loads, enabling precise emission calculations with minimal intrusion. The real-time feature further enhances this framework providing decision-makers with tools for strategizing emission reduction measures within industrial operations. Case studies will be given to demonstrate the effectiveness of the framework compared with other common approaches.

Title of speech: Turquoise Hydrogen: A possible solution for renewable energy scarce countries in energy transition period

Abstract: The pursuit of energy availability, affordability, and sustainability has always been paramount in any nation's energy transition plan, echoing the principles outlined in the World Energy Council's Energy Trilemma. This trilemma emphasizes the importance of energy security, equity, and environmental sustainability. The concept of a Hydrogen Economy has emerged as a potent vision, aiming not only to decarbonize the global economy but also to address energy security concerns by leveraging hydrogen, which can be extracted from various sources, including water. Importantly, when hydrogen is used for energy production, it generates water as its sole by-product. However, despite its promise, the Hydrogen Economy remains complex and challenging to implement at scale, primarily due to its reliance on two distinct supply chains: one for hydrogen production and another for energy conversion systems. The widespread adoption of this model hinges on achieving affordable costs for both hydrogen and energy conversion technologies. In countries with limited access to renewable energy resources like Singapore, hydrogen production using renewables is constrained, and importing hydrogen from abroad often proves cost prohibitive. As a result, conventional methods such as steam methane reforming (SMR) remain prevalent, despite their significant carbon emissions. To mitigate the environmental impact of hydrogen production, alternatives like Carbon Capture and Sequestration (CCS) are considered. However, implementing CCS in geographically constrained regions like Singapore presents challenges. Instead, methods such as methane cracking offer a promising solution. By splitting methane (or natural gas) into hydrogen and solid carbon, these processes produce little to no CO2 emissions. The presentation will commence with an overview of Singapore’s long-term energy plan and research focus, followed by an exploration of several major initiatives regarding hydrogen applications. Finally, it will delve into the catalytic decomposition of methane for hydrogen production, serving as an interim solution during the energy transition period.

Title of speech: Frequency Coupling Characteristic Analysis and Stability Improvement of Renewable Power Generation Systems

Abstract: It has been reported that when connected with low short circuit ratio (SCR) grid or diverse grid transmission infrastructure, the renewable power generation systems have some broadband resonance risk such as sub-synchronous resonance (SSR), sub/super-synchronous oscillation (SSO) and high-frequency resonance (HFR). The impedance-based method has been proven to be a useful method to analyze these instability issues. However, the frequency coupling characteristic between positive- and the negative-sequence complicates the stability analysis and improvement for large-scale renewable power system. This report establishes the frequency coupling characteristic model for renewable power system, and locates the dominant factor within each frequency band, then the s-domain nodal admittance matrix and the broadband passivity enhancement considering frequency coupling characteristic are proposed.
