Keynote Speech: Response-controllable PQ Control for Microgrids: Model-Based Analysis and Physics-Informed Learning

A microgrid may accommodate inverter-based renewable resources for PQ control in both grid-connected and islanded modes. Existing controllers, such as proportional-integral (PI) controllers, require sophisticated gain tuning and do not track the pre-defined trajectory accurately. To have a customized PQ response, we propose a time-varying-gain based PQ control method for microgrids based on a combination of model-based analysis and physics-informed machine learning. With the hybrid approach, inverters can be freely assigned exponential response time constants without manual gain tuning, which benefits microgrid performance under various disturbances.

Keynote Speech: Data Driven Solutions for Future Sustainable and Resilient Energy Systems


As a result of high penetration of power electronics connected generation and load, as well as mixed ac-dc transmission and distribution networks, the nature of dynamics of modern electrical power systems has changed and their operation became a challenge, requesting new approaches for monitoring, protection and control. On the other hand, availability of modern smart technologies, e.g. sensor and ICT technology, opened new paradigms and data driven solutions for coping with new challenges. The presentation is aiming at addressing new data-driven approaches for monitoring, protection and control of future sustainable and resilient energy systems.

Keynote Speech: Grid Modernisation for Smart and Carbon-Neutral Cities


In 2015, countries around the world reached the Paris Agreement to start reducing emissions as soon as possible to deal with the increasingly dominant issue of climate change and achieve the carbon neutrality target. Many countries, including China and the USA, have proposed national strategies to strengthen their power grids to facilitate major government initiatives, such as increasing the penetration of renewable energy as well as the electrification of transportation and other business and industrial sectors. Besides, the initiative of smart cities is promoted to improve the quality of our life. A reliable and sustainable power grid is recognized as a key enabler for smart and carbon-neutral cities. Hundreds of billions of US dollars have been and are being spent on modernising existing power grids. In this speech, the latest developments, challenges and opportunities in grid modernization for smart and carbon-neutral cities will be presented, and some key technologies will then be discussed.

Keynote Speech: Smart, Energy-efficient and Grid-interactive Buildings: Technology Development and Benefits


Effective use of renewable energy resources together with effective energy storage and high energy efficiency could allow low-rise buildings in low density districts to achieve carbon neutrality. However, in high-density cities like Hong Kong, it is obviously impossible for high-rise buildings to achieve carbon neutrality themselves by adopting the same approach. How to achieve carbon-neutrality and what should be effective contributions of high-rise buildings in high-density cities need to be reconsidered. Energy flexibility and efficiency could be the practical and effective contributions of high-rise buildings to contribute to the overall carbon-neutrality by facilitating the high renewable penetrations in power grids. This presentation will discuss the potential approaches for achieving carbon-neutrality and the roles of buildings in high density cities. The research work on building flexibility enhancement and grid-interactive control technologies for unlocking building energy flexibility will be also presented.

Keynote Speech: Construction of New Electricity Market for Entities of Aggregated Distributed Resources —Taking the Hunan power system as an example

Keynote Speaker: Prof Hongming Yang


Nowadays, the power system is translating to a renewable-dominated system, which aims to reduce carbon emissions. As a typical renewable-dominated power system, the Hunan power system meets the risk of power shortages during summers and winters, nevertheless, with a limited renewable energy accommodation. Our research team engages in the electricity market for distributed resources, and devotes to establishing a reasonable new electricity market to increase the flexibility of the system.

Based on the plan-market cooperation, inter- and intra-provincial cooperation, and medium- and long-term and spot market cooperation, the transaction mode for the new electricity market is demonstrated. The special transaction models for wind power curtailment and in-depth peak regulation are presented.

Keynote Speech: Energy Storage Power Conversion and Future Fuel For Electric Vehicles


The electric vehicle is one of the major development of this century. Carbon Neutrality 2050 triggered the rapid development of electric vehicle technology. Energy storage and fuel are the major concerns the future development.     The present Li-ion Battery suffers from recycling and its carbon footprint issue. Hydrogen fuel could be a good choice, but there are numerous issues to be solved because of production, transportation, and safety.   Other energy storage, such as metal-oxide fuel cells, is also a good alternative. Recently the ammonia power electric vehicle has been promoted because it is operated under low pressure and also its potential low cost.

Vehicle technology is based on power electronics. The power circuit, drives, motor, charger, and power distribution are all critical parts for power conversion. In this talk, the new technology of various energy storage, power conversion techniques and new fuel power processing will be discussed.
