Session Abstract
Under the strategic framework of "carbon peaking and carbon neutrality," the construction of clean, low-carbon new power systems featuring the integration of high-penetration renewable energy is advancing rapidly. Within these new power systems, the generation, distribution, and consumption of electrical energy exhibit increasingly prominent direct current (DC) characteristics. Consequently, integrating these components into traditional alternating current (AC) distribution networks introduces challenges such as low efficiency and high energy losses.
By minimizing the AC/DC conversion stages between sources and loads, DC power supply and distribution technology has emerged as a crucial pathway for transforming power supply paradigms, enhancing energy utilization efficiency, and facilitating the broader energy transition. The development and innovation of DC distribution technology directly determine the depth and breadth of this energy transition. It serves as an essential technical mechanism for achieving the efficient accommodation of green electricity and driving the ongoing construction and development of new power systems.
