A Modified Power System Information-Physics Cooperative Attack Model and Its Influence

This paper establishes a two-layer information physical cooperative attack optimization model from the perspective of attackers and accesses the impact on the power system under this attack. Therein, the upper model describes the strategy of cooperative optimization attack, and the lower model describes the optimal scheduling mechanism of operators. The double-layer optimization model is transformed into a single-layer optimization model by the KKT method, and the Matlab program of the cooperative attack model is compiled. Finally, we analyze the improved IEEE RTS-79 test system to access the loss of load and verify the correctness of the proposed model.
