Keynote Lecture: Optimal Voltage Ride-Through of IBR-Dominated Power Systems

Abstract: With the increasing penetration of inverter-based resources (IBRs), disconnecting IBRs from the system “at first sign of trouble” could exacerbate system instability under large voltage disturbances (sag, swell and unbalance). Several large blackouts or interruption events in relation to the improper operation of IBRs under voltage disturbances have been reported in recent years. Although a consensus has been reached that IBRs should be able to ride through various voltage disturbances while providing dynamic voltage support (DVS) to the grid, it is still not clear how to achieve the optimal DVS. This talk will share our recent research efforts in improving the DVS performance of IBRs under abnormal voltage conditions. Three critical questions are answered via optimisation. 1) What is the maximum DVS capability of a single IBR? 2) How to implement the maximum DVS without relying on the knowledge of grid model parameters? 3) How do multiple IBRs interact with each other in a network? The optimisation-based methodologies open up an effective way to explore sophisticated control strategies of IBRs under large disturbances, and the research findings complement and even challenge our physical intuition.

Keynote Lecture: Operation and Control of the New Power Systems Based on Hierarchical Clusters

Abstract: The development of new power systems will inevitably lead to major changes in the patterns of the power systems. With the constantly growing renewable energy penetration and the widespread application of power electronic equipment, the types of energy sources and loads accommodated in the power systems will continuously increase in the future and the complexity of operation and control will also rise sharply. This paper describes a new paradigm of the large-scale power systems divided into multi-level smaller-scale power systems containing distributed resource clusters. Each resource cluster has the capability of electric power supply, consumption and exchange, and manages to achieve power balance and autonomously optimal operation. This paper proposes the three-layer network (energy network, information network, value network) architecture and overall research design of the new hierarchical cluster power systems. At the energy network level, the technical characteristics and patterns of the new hierarchical cluster power systems are proposed, and China’s current relevant policy support is introduced. At the information network level, after introducing the problem of distributed sensing and information fusion in the new power systems, the focus is put on the application of swarm intelligence and cooperative control theories and technologies (especially the frequency control problem). At the value network level, new transaction mechanisms and business models such as distributed resource peer-to-peer transactions and virtual power plants are introduced. Finally, the frontier research directions of new power systems are discussed from the perspective of complex system theories based on multidisciplinary research.

Keynote Lecture: Talkative Power Conversion For Smart Power-Cyber Applications

Abstract: The power electronics converters have been widely used in different fields in terms of smart home, industrial automation, electrical transportation, aerospace, and modern power system (wind energy, photovoltaic system, energy storage system and electrical vehicle charging station, HVDC and various flexible equipment). The smart operation and management of the aforementioned systems relies on a reliable communication system, which is used to transmit the operation information and status to intelligent agents to make an optimal decision for the power electronics converters-interfaced resources, due to the flexible control capability of power converters.
    The talkative power conversion, which embeds the information into power via either reference or carrier-based modulation with zero extra hardware cost, can transfer the power and information simultaneously to enable wired or wireless smart power-cyber applications, with an acceptable communication bandwidth, thanks to the wide band gap devices. The talkative power conversion is an interdiscipline, bridging different realms of knowledges between the electrical engineering and communication engineering, and will open a new era to rethink the topology, modulation and control for power converters, which enable power-cyber functionalities.
