전력설비 특허 동향 분석 및 부상기술 동향에 대한 고찰

The electric power facility industry were started with all transmission and distribution devices, from power plants that produce electricity to consumers who use electricity. Major domestic power companies are concentrating on decarbonization, decentralization, digitalization, deregulation, and energy democratization as the policy direction to implement the decarbonization strategy. Although it seems a bit complicated, the reality is that the strategy of increasing the proportion of new and renewable power generation through the expansion of new and renewable business is the main issue. Therefore, as the main DC power source of renewable energy sources is connected to the transmission and distribution system, it is expected that the investment related to the safe system operation and DC facility will continue to increase. In this regard, the renewable and DC-related power facility industry is also expected to grow together. In this paper, based on patent information, the recent patent trends in the electric power facility field of IP5 countries in the United States, Europe, Japan, China, and Korea were analyzed quantitative and qualitative, respectively. The emerging technology trends were analyzed through activity and technology index analysis.
