Research Trends in High Voltage Power Transmission

High-voltage transmission is the most pivotal process in the electrical power industry. This critical aspect is enabling efficient and long-distance electricity transfer. It requires a robust infrastructure that can last for decades without causing impairment in human life. Research in this field continually evolves to address efficiency, reliability, and sustainability challenges. Due to global warming, the power transmission system has started to experience some challenges, which could presumably escalate more in the future. These challenges include renewable energy integration, extreme weather conditions, and growing electricity demand. In this paper, research efforts aimed at addressing these challenges are discussed. In particular, we focus on research in grid modernization, regenerative electric energy, grid resilience, policy and regulation, based on the transmission possibility. We conclude by drawing attention to specific areas that we believe need more research.
