High Impact Local Load Redistribution Attack Without Confidential Network Information

In a Load Redistribution (LR) attack, the attacker manipulates the loads to affect the economic operation of the grid adversely. The existing works in this domain can be grouped into two categories: high-impact non-local LR attacks in which all the loads are manipulated to increase the operation cost of the grid significantly, and low-impact local LR attacks in which only selected loads are manipulated without significantly increasing the operation cost. This letter proposes an iterative approach for high-impact LR attacks in which only selected loads are manipulated to increase the operation cost significantly. The case study on various IEEE test systems validates the effectiveness of the proposed approach.
