Abstract: Based on the definition and principle of power system resilience, combining the traditional energy storage equipment with the demand response, an optimization method of power system operation resilience considering generalized energy storage is proposed. Five attack schemes based on topology are evaluated according to four indexes, and the most disadvantageous attack strategy is selected to simulate the damage of power system. Taking the minimum operating cost of the system as the objective, a combined scheduling model involving wind power station and energy storage unit is carried out. A generalized energy storage scheduling method is proposed to improve the resilience of power grid in operation period in recovery stage, and an optimal model of disaster recovery is established to maximize the system resilience. The optimal recovery strategy is calculated by genetic algorithm. The IEEE 30-bus system is taken as an example to verify the effectiveness of the generalized energy storage in improving the system performance and the resilience of power grid operation.
