    Abstract:

    With the fast development of the economy and society, the reliable supply of electricity has triggered a wide range of concerns. On 15th, February, 2021, a large-scale power outage occurred in Texas, USA due to the extremely cold weather. More than 4.8 million users are affected. This accident has a serious impact on industrial production and people's lives. Firstly, the general situation of the power system in Texas is briefly introduced, and then the specific process of the blackout is described in chronological order. After that, the causes of the blackout event are analyzed from three aspects: grid adequacy, regional support capability, and the market mechanism. Finally, from the perspective of the construction of China's new power system, some inspirations are proposed for the meteorological forecasting technology applications, the power supply structure of the new power system, the flexible resource and integrated operation of the source-grid-load-storage system, and the construction of the grid structure of the power grid. This work provides a reference to help guarantee the adequacy of the power supply in China's new power system.
