Abstract: In recent years, extreme weather has occurred frequently, and the resilience level of the power system needs to be effectively improved. In this paper, we study the energy storage configuration of the power grid in the black start and propose a hybrid configuration scheme of mobile energy storage and stationary energy storage, considering the uncertainty of new energy to enhance the flexibility of the black start of the power grid. Firstly, considering the dynamic operation process of mobile energy storage in the power grid, such as driving state and driving time, the spatiotemporal interaction model and operation scheduling model of mobile energy storage are established. Secondly, the black-start power supply in the power system is analyzed and modeled, the uncertainty of new energy output is considered in the application scenario method, and the ramp-up rate and active power change of thermal power units in the recovery process are analyzed. Then, combined with the operation model of stationary energy storage, the optimal configuration model of hybrid energy storage for the black start of the power system is established with the depreciation of investment cost and operation and maintenance cost of mobile energy storage and stationary energy storage as the objective function. The model considers the load recovery requirements of the system in the black start, responds to the unsafe disturbance of the system from the perspective of load stability, and constructs the recovery model of each unit, node, and line in the black start. Finally, an improved IEEE 30 node example is used to verify the effectiveness of hybrid configuration mobile energy storage and stationary energy storage in improving the power system's resilience in extreme events, which provides reference value for practical engineering.
