and monitoring and protection devices

is a typical cyber-physical system. The coordinated control of each unit in the microgrid mainly relies on the reliable information system. Once the failure of information system happens

the microgrid operation reliability will be affected. This paper presents a method of quantitatively analyzing the influence of the information system component failure and channel quality on the microgrid operation reliability. Firstly

the static link model and the dynamic transmission model of the information system are established. Then the operation process of the microgrid is simulated by the Monte Carlo method. With the expected energy not supplied(EENS)and the loss of load probability(LOLP)as indices

the influence of the information system on the microgrid operation reliability is quantitatively analyzed. In the light of the information system component failure and the channel quality

the sensitivity analysis of the microgrid operation reliability is carried out. Numerical example results verified the effectiveness of the proposed model and method. This work is supported by National Key Research and Development Program of China(No. 2016YFB0900105)
