Anti-vulnerability evaluation method and system for urban power grid

The invention discloses an anti-vulnerability evaluation method and system for an urban power grid. The anti-vulnerability evaluation method comprises the steps of S1, establishing an urban power gridvulnerability index evaluation system according to urban power grid characteristics; s2, recognizing and evaluating the urban power grid from a power supply structure, a power grid structure, power grid operation, communication coupling and external supply through an urban power grid vulnerability index evaluation system, and obtaining the vulnerability and vulnerability area of the urban power grid; s3, acquiring power failure loss of the attacker and/or the defender by taking the attacker and/or the defender as a set target according to the vulnerability and the vulnerability area; and S4,carrying out corresponding simulation decision making according to the power failure loss. 本发明公开了一种用于城市电网的对抗脆弱性评估方法及系统，对抗脆弱性评估方法包括：步骤S1：根据城市电网特征建立城市电网脆弱性指标评价体系；步骤S2：通过城市电网脆弱性指标评价体系从电源结构、电网结构、电网运行、通信耦合以及外部供给对城市电网进行识别和评价，并获得城市电网
