摘要：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.

摘要：Recent years, renewable energy is experiencing a rapid growth, large number of renewable energy sources have been installed and connected to power systems. In addition to the large centralized wind farms connected to transmission grids, many distributed wind turbines and PV panels are operated as distributed generators in distribution systems. Traditional power system is undergoing a transformation and upgrade towards a new-type power system dominated by renewable energy sources. This presentation discusses several applications of artificial intelligence in new-type power systems, including the European and Chinese experiences. Some of our research at Institute of Smart Power and Energy Systems (ISPES), University of Electronics Science and Technology of China (UESTC) will also be introduced.

摘要：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.
