Speech Title: Secure Operation and Control of Smart Urban Power Grids
Abstract: In response to the Carbon Neutrality target, traditional urban power grids have gradually become so-called active distribution networks (ADNs) featured by large-scale integration of distributed energy resources (DERs) such as renewables and electric vehicles (EVs). These massive DERs have dramatically transformed the way in operation and control of modern urban power grids, which has posed insecurity threats and critical challenges to distribution system operator (DSO). On the other hand, the emergence of advanced IoT devices equipped with monitoring, computing and communication functions and power electronic converters have made the modern urban power grids more observable and controllable, enabling smart urban power grids. This presentation will firstly introduce the developing trend and growing challenges for smart urban power grids during the low-carbon transition. To deal with these emerging issues and operational security risks resulted from the decarbonization, the presentation will then move on to some latest developed voltage and frequency regulation techniques and energy management & market tools to effectively accommodate and utilize the increasing DERs and enable the secure operation and control of smart urban power grids.

Speech Title: Soft Open Points in Flexible Distribution Networks
Abstract: Soft open point (SOP) is a novel power electronic device that promotes flexible operation of distribution networks. SOP can rapidly and accurately adjust power flows among connected feeders with multiple voltage levels. Thus, it can flexibly support many scenarios such as high integration of distributed energy resources, efficient operation of distribution networks, and high reliability of power supply. First, this research analyzes the SOP-centered coordinated control to cope with strong source-load uncertainty. The flexible operation based on SOP has been verified on voltage violation alleviation/feeder load balance/source-load interaction etc. Second, the improvement of SOP on the restoration performance of distribution networks is analyzed. The coordinated principles of SOP and conventional restoration means are formulated. The SOP-organized islanding of source-network-storage-load resources is proposed to maintain uninterrupted power supply for critical loads. Finally, the future development direction of flexible operation of SOPs for new-type distribution networks is prospected.

Speech Title: Multi-Physical Field Coupling Degradation Mechanism of Composite Insulation in Cable Terminals
Abstract: Cable terminals represent critical yet vulnerable components in power transmission systems, particularly under high-voltage DC applications and constrained installation environments such as high-speed railways. Statistics indicate that up to 70% of cable system failures originate from terminals, often due to the synergistic effects of electrical, thermal, and mechanical stresses on their multi-layer composite insulation structure. This study systematically investigates the electro-thermal-mechanical coupling degradation behavior of cable terminals under static and dynamic mechanical loads. Through finite element simulation and experimental validation, we analyze the distortion of electric and thermal fields within the insulation under varying bending radii. Results show significant field heterogeneity due to geometric deformation, with enhanced electric field intensity near the skirt region and nonlinear temperature gradients accelerating local aging. A key focus is placed on the evolution of interfacial pressure between silicone rubber (SiR) and cross-linked polyethylene (XLPE) insulation under multi-stress conditions. Thermo-mechanical cycling combined with bending stress leads to accelerated stress relaxation and material chain scission, reducing interfacial pressure by up to 40% after aging. Nonlinear pressure distribution under bending is identified as a core factor driving insulation degradation. Further analysis of surface flashover characteristics under non-uniform interfacial pressure reveals intensified discharge initiation and asymmetric carbonization paths. In-situ infrared spectroscopy and discharge trajectory analysis demonstrate that pressure heterogeneity aggravates solid dielectric polarization and gas-solid discharge channel expansion, reducing flashover voltage by 15–25%. The research provides a mechanistic framework linking macro-scale performance degradation to micro-scale structural changes, supported by molecular dynamics simulations. Findings offer practical insights for optimizing cable terminal design, condition monitoring, and lifespan prediction in complex operational scenarios.
