A Novel Finite-Time Control Scheme for Enhancing Smart Grid Frequency Stability and Resilience

In this paper, a novel distributed finite-time control scheme is proposed to enhance the resilience and frequency stability of smart grid by utilizing a distributed energy storage system (DESS). The proposed entire framework integrates the traditional governor-based control and excitation control with DESS-based control. The design objectives also address some practical challenges including communication delay, limited DESS capacity or absent DESS, and voltage dynamic and denial-of-service (DoS) attacks. The proposed excitation control can enhance the performance of other existing approaches for utilizing DESS. The IEEE 68-bus power system and East China Power Grid are used to validate the effectiveness of the proposed control framework in enhancing the frequency stability and resilience of smart grid.
