Risk Assessment of Smart Grid Cyber Security Based on Multi-Level Fuzzy Comprehensive Evaluation Method

Abstract:

This paper proposes a comprehensive risk assessment index system for Smart Grid cyber security, including five first-level indicators such as entity and environment security, management security, data security, software security and communication security. Every indicator includes specific sub factors. The cyber security risks for Smart Grid are emphatically analysed. The paper integrates AHP with Fuzzy evaluation method, through which the weight of each layer and the risk assessment matrix are determined. Practical case study shows that cyber security level of the Smart Grid is good, but it needs improvement and reinforcement in organization system, data signature, data backup and intrusion detection system.
