Materials are the heart of engineering systems. Sustainable power grid involves adopting a diversified power generation platform, incorporating wind, solar, and wave energy sources, utilizes submarine cables and direct current transmission and distribution equipment to transfer power energy to the focal points of burden, whose stability heavily depends on the reliability of the power equipment especially the dielectric materials at each key node. In recent years, severe power accidents induced by limited material properties occur frequently, especially in the frontier fields of gas-insulated transmission equipment, UHV converter station, underground power station, energy storage station and so on. As a result, the research and development of high--performance dielectric materials are closely linked to the secure of future power grids.
With the advancement of computer technology and the cross-integration of disciplines as chemical engineering, polymer materials, condense physics, and electrical engineering, novel methodologies and technologies are continuously emerging. Specific progress is demonstrated in research areas such as the substitution of SF6 with eco-friendly gases, measurement/diagnose for new-type composite materials, multiscale simulation, machine learning, and the intelligent manufacturing. Therefore, this session aims to provide a communication platform for researchers, scientists, and engineers to share their cutting-edge discoveries related to high-performance insulating materials, and will foster knowledge exchange and promote further advancements in this field.
