Shenzhen's urban distribution network construction is based on the characteristics of a megacity with high load density, high reliability requirements, high power quality, and limited land resources. Aiming to become a world-class digital grid and a benchmark for new power systems, it has established a modern framework integrating "a robust main grid, self-healing distribution network, digital twin technology, and green low-carbon development." The city's power supply reliability and level of intelligence rank among the world's best, fully supporting the development of the Guangdong-Hong Kong-Macao Greater Bay Area and the pilot demonstration zone for socialism with Chinese characteristics.
