摘要
针对电网信息物理系统可能遭受的恶性数据注入攻击以及海量的测控数据和复杂的运行方式,提出了一种线下优化部署相量测量单元(PMU)的保护方案。以线性恶性数据注入攻击模型为例,首先采用行最简形矩阵转换方法建立了一套攻击者为攻击指定数量状态量的最小代价攻击模型。然后,针对最小代价攻击模型,提出了一种有效防御并保证全系统可观的相量测量单元优化部署策略;为使该保护策略能够运用于大型电网,提出了一种分区自治保护方案。最后通过IEEE 9节点、IEEE 14节点和IEEE 30节点系统算例验证了所提线下保护模型的有效性。
Aiming at the malicious data injection attack&massive measurement and control data and complex operation mode that cyber physical system may suffer,a protection scheme of offline optimized deployment phasor measurement unit(PMU)is proposed.Taking the linear malicious data injection attack model as an example,a set of minimum cost attack model for the attacker to specify the number of states for the attack is firstly established by using the transformation method of row minimax matrix.Then,based on the least cost attack model,an optimal deployment strategy of phasor measurement unit is proposed which can effectively defend and ensure the overall system's observability,which guarantees the system considerable.In order to make the protection strategy applicable to large power grids,a regional autonomous protection scheme is proposed.Finally,examples of IEEE-9 node,IEEE-14 node and IEEE-30 node systems are presented to verify the effectiveness of the proposed off-line protection model.
