Research on Power System Restoration Ability Evaluation Method

Real-time evaluation of power system restoration ability helps to make power supply restoration decisions after power outages, and can also provide reference for planning and design of resilient power systems. This paper proposes a priori evaluation method of power system restoration ability to evaluate its own restoration ability, and further establishes a posteriori evaluation method of power system restoration ability considering the effect of restoration measures. In order to simulate the effect of restoration measures, a system restoration control optimization model with the aim of maximizing the expected net income is established. Finally, the IEEE 70 node example system is used to verify the effectiveness of the proposed method.
