As more and more variable resources and demand response resources being integrated in the power grid, the grid operation is experiencing increasing level of risk. The spreading of a small failure can result a big disaster in many large-scale electric systems. Failure modes and effects analysis (FMEA) is a traditional risk analysis method that has a worldwide recognition across many industries. This paper proposes a formal modeling approach for power grid operation risk, which defines the failure modes as the inherent properties at different system hierarchical levels. It is a structured modeling technique for representing FMEA causal knowledge in unified mathematical language, which in turn provides the framework for organizing the failure modes, the causes and effects more systematically. Using the iterative search process operated on the reasoning matrices, the effects analysis for more than one bottom-level failure event can be realized automatically. The result points out more important focus to handle, advance the treatment order of the failure events, and so improve the efficiency of risk management.
