Linear Power Flow Model Based Load Redistribution Attack on Voltage Security

Load redistribution attack (LRA) has been arisen as one of the typical stealth false data injection attacks (FDIA) in modern power systems. Traditional LRA focuses on altering the active power measurement unit on load buses and branches to increase the system operating cost. This paper proposes a new type of LRA that aims to sabotage the nodal voltage of certain target bus. In our new model, attack resources are not only limited to active power, but reactive power is also included to launch a powerful attack. Moreover, a linear power flow model is introduced to reduce the complexity of the model. Simulations on IEEE 30-buses system has proved the effectiveness and advantages of the new attack strategy.
