Abstract：Flexible multi-state switch (FMSS) is connected to the distribution network, which can realize the optimal operation of the distribution network under normal and faulty conditions through active control. The access of FMSS and the increase of distributed generations make the distribution network more dependent on active control. In order to reduce the operation risk of network when control information fails, this paper proposes an optimization method of centralized-decentralized coordinated control strategy for distributed resources considering cyber failures. First, the model of flexible distribution network cyber physical system is established and the control mode under different operation states is analyzed. Then, adaptive FCM clustering method and fault tree analysis method are used to deal with the uncertainties of operation scenarios and cyber failure scenarios. On this basis, a bi-level optimization model of centralized-decentralized control strategy is established with the aim of minimizing the comprehensive risk of voltage deviation and load loss. The model is solved by intelligent optimization algorithm and second order cone programming. Finally, taking three IEEE 33 bus systems connected by FMSS as test example to verify the effectiveness of the strategy.
