A Review of Reliability, Vulnerability and Resilience Analysis of Smart Grid Based on Complex Network

As a safety-critical system, the reliable operation of smart grids is crucial to economic prosperity and social stability, and reliability analysis and evaluation is one of the effective means of achieving this goal. With smart grids continue to grow in size and complexity, complex network analysis are of useful to understand salient properties of complex systems by modeling smart grids as network system. In light of this, many studies analyze the reliable degree of smart grid from multiple scales reliability, vulnerability, resilience, stability, robustness, survivability, etc. Whereas, those concepts are both different and similar to each other, which tend to be confusing for beginners. This paper holds that reliability, vulnerability and resilience are three important concepts which can representatively describe the reliability level of network of smart grid during and after perturbation, and aims to provide a focused overview of complex networks-based reliability, vulnerability, and resilience analysis for smart grid. We hope this survey will bridge academic researchers and industry engineers in adopting appropriate issues for possibly depth future cooperation.
