Abstract
Moving target defense (MTD) strategies significantly protect power systems against stealthy false data injection attacks. However, traditional MTD approaches in power systems predominantly focus on single-parameter perturbation, leaving gaps in addressing the complexity and unpredictability of attack surfaces. In this work, we present a novel MTD strategy that departs from the traditional approach and utilizes multiple parameter perturbations to enhance the resilience of power systems against cyber threats while ensuring system stability. Our contributions include investigating the impact of individual and combined parameter perturbations on power system stability and performance, utilizing voltage sensitivity analysis to identify critical parameters, and considering the trade-offs between system security and operational constraints. The proposed algorithm dynamically perturbs the selected parameters, incorporating insights from the power flow Jacobian matrix analysis, and continuously adapts the MTD strategy based on the obtained results.
