Original abstract
Hydroelectric power plants are increasingly integrated into digitalized, renewable-supported power systems, where voltage regulation, reactive power support, and automated transformer tap control are essential for secure operation. However, this digitalization also expands the cyberphysical attack surface of hydroelectric substations and their associated load-tap changer (LTC) transformers. This chapter presents a remedial control framework for hydroelectric power plants under false data injection (FDI) attacks targeting LTC transformer-based voltage regulation pathways. The proposed framework models the interaction among hydroelectric excitation-driven voltage support, LTC tap-changing actions, cyberinduced measurement manipulation, and adaptive network support. A hydroelectric voltage consistency assessment is introduced to distinguish suspicious cyberinduced behavior from normal renewable-driven fluctuations. The proposed remediation approach suppresses reliance on suspicious control channels while activating trusted hydroelectric support resources, noncompromised LTC corrective actions, and topology-oriented network support. A modified 136-bus renewable-integrated distribution system is used to evaluate the framework under cyberphysical disturbances. Simulation results demonstrate that FDI attacks can degrade voltage profiles across hydroelectric-supportive corridors, while the proposed remedial strategy restores voltage conditions toward secure postremediation operating regions. The chapter emphasizes the role of hydroelectric power plants as active resilience-oriented assets capable of supporting voltage recovery, cyberphysical remediation, and secure operation in hybrid hydro–solar–wind power systems.
