摘要：
Microgrid, which integrates distributed generators, energy storage systems, energy conversion devices, load, 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. © 2016 Automation of Electric Power Systems Press.
