Introduction Shenzhen is a national strategic hub city of the Guangdong-Hong Kong-Macao Greater Bay Area and a pioneering demonstration zone of socialism with Chinese characteristics. In order to ensure the reliability of electricity production and life of the citizens, Shenzhen urgently needs to study measures to improve the grid's resistance to natural disasters such as typhoons, lightning and floods. Method Based on the successful experience of power system disaster prevention and mitigation, disaster reduction and relief as the research basis, the basic concepts, basic principles, and construction goals for strengthening local power grid disaster prevention, reduction, and relief were proposed. In addition, this article proposed key measures for building a strong local power grid from the aspects of planning, construction, operation, maintenance, and application of new technologies.
Result Focusing on important users and building a strong power grid covering the main core areas of the city, this article further integrates the connection corridors for fast power recovery, and the main power transmission channels for disaster protection to form a strong local power grid.
Conclusion The research results are conducive to Shenzhen's adaptation to the urban and grid development planning of the Guangdong-Hong Kong-Macao Greater Bay Area. And it is of great significance to the construction of power grids in other important cities and natural disaster-prone areas in China.
