摘要：
Aiming at the critical load restoration using distributed energy storages and generators in distribution networks with multiple types of energy storage after blackouts, considering the operational and functional characteristics of energy type and power type energy storage, a two-stage coordinated restoration method is proposed to realize the coordination and complementary among multiple types of energy storage and achieve better restoration effect. In the first stage, a mixed-integer second-order cone programing for multi-period restoration problems considering operation characteristic of energy type energy storage is built, which can decide load restoration sets in each period and planned power curves for sources, i.e. the optimal allocation scheme of energy in the time dimension is determined. In the second stage, based on the energy allocation scheme given in the first stage, considering fast power support of the power type energy storage, the actual power curves for all sources during the periods of load pick-up are determined, i.e. the refined allocation scheme of power is determined. A modified IEEE 33-bus distribution system is used to verify the effectiveness of the proposed two-stage coordinated restoration method. © 2022, Electric Power Automation Equipment Press.
