A Blocking Control Strategy of Cascading Failure for Cyber-physical Power Systems Considering Energy Storage
In the context of the high integration of information technology into power systems,an optimization strategy considering energy storage configuration for blocking control was proposed to mitigate the risk of cascading failures in cyber-physical power systems.Firstly,based on the observability and controllability of the power system,the multi-level interaction mechanism of information and physics was con-structed,and the evolution process of cascading failure dominated by overload was clarified according to the interaction among systems.At the same time,the influence of energy storage connected to the power system on cascading failure blocking control was considered based on the existing regulatory means.The blocking control was described as a multi-stage optimal power flow problem,obtaining a cascading failure control scheme that balances safety and economy.The comparison of different control strategies on the IEEE-118 node system demonstrated the effectiveness of the proposed control optimization strategy and analyzed the impact of energy storage scale on blocking control.
