I am glad to write this report on the successful completion of my project as proposed in my contribution for the DEIS Graduate Student Fellowship. I extend my sincere thanks to the DIES Education Committee for granting me the DEIS Graduate Student Fellowship. I am also thankful to my PhD supervisor Prof. Sisir Kumar Nayak for his support and mentoring during the implementation of this project. This fellowship strengthened morale and boosted confidence during my PhD. I got an opportunity to collaborate with Prof. Manu A. Haddad from the Advanced High Voltage Engineering Research Centre, Cardiff University, on this project, whose input helped me improve the way I presented this work. It also helped me network with renowned academicians when I presented my work at the International Conference on Dielectrics (ICD) 2024 in Toulouse, France. I strongly believe that this fellowship helped me grow to new heights in my career.
我很高兴能撰写这份报告，汇报我成功完成了我在申请 DEIS 研究生奖学金时提出的项目。我衷心感谢 DIES 教育委员会授予我 DEIS 研究生奖学金。我还要感谢我的博士生导师 Sisir Kumar Nayak 教授在项目实施过程中给予我的支持和指导。这项奖学金鼓舞了我的士气，增强了我攻读博士学位的信心。在这个项目中，我有机会与卡迪夫大学高级高压工程研究中心的 Manu A. Haddad 教授合作。当我在法国图卢兹举行的 2024 年国际电介质会议（ICD）上介绍我的工作时，它还帮助我与知名院士建立了联系。我坚信，这项奖学金帮助我在事业上达到了新的高度。

To address the swift expansion and critical demand for renewable energy, high voltage direct current (HVDC) electric power interconnections between power grids, nations, and even continents are set to assume a greater significance in ensuring a dependable and resilient power supply than they did in the previous decade. For instance, the inaugural 400-kV DC interconnection, linking Belgium and the UK using cables insulated with cross-linked polyethylene (XLPE), was established in 2019 [1] and has been operational to accommodate fluctuating power requirements, particularly in the UK. This HVDC link between Belgium and the UK, called the NEMO link, was constructed using innovative voltage source converters (VSC). On the other hand, numerous 350- to 450-kV HVDC systems employing conventional line-commutated converters (LCC) remain in the world, and some have been operated for over 25 years. In such LCC HVDC systems, cables insulated with oil-impregnated paper, such as self-contained fluid-filled (SCFF) or mass-impregnated (MI) cables, are used. However, some have deteriorated after a long service due to malfunctions such as oil migration and fatigue fracture of lead sheaths around insulation caused by heat cycles. In general, LCC, probably receiving lighter external stresses than undersea cables, seem to be more robust and require less maintenance than cable systems. Consequently, replacing outdated paper-insulated cables with XLPE cables is a beneficial upgrade, while keeping the same converter.

It is hard to believe that the end of the year is nearly upon us. This year has been filled with several great DEIS events and conferences, including EIC, ICD, and CEIDP. Each event has allowed members to meet in person and, in some cases, to see their long-time friends. In other cases, members had an opportunity to meet new colleagues and bright young minds that will hopefully become new friends. These events are always a sharing of knowledge and experience coupled with social networking.

Polymeric insulation is widely used as the main insulation of power equipment and electronic devices. When DC voltage is applied on the polymer insulation, space charge may accumulate inside and cause electric field distortion. So, space charge accumulation is important for HVDC insulation materials. The origin of the space charge is considered to be from ionization and charge injection. The space charge accumulation is determined by the charge injection, transportation, extraction, trapping, and other factors. The charge injection rate at the electrode/insulation interface is a key factor that determines the charge accumulation inside insulation material.
