Abstract | To achieve a better frequency control performance for multi-area power systems, this paper proposes a novel decentralized event-triggered control (ETC) algorithm for automatic generation control (AGC) to replace the traditional periodic sampling/communication mechanism. For each control area, decentralized event-triggering conditions that only depend on locally available information are designed for the control center to determine time instants when to sample the frequency and for each communication channel to decide instants when to broadcast corresponding information. Further, a strictly positive dwell time is introduced to prevent Zeno behaviors. Small disturbance frequency stability of the interconnected power network under the developed ETC law is analyzed, and a sufficient stability criterion on the selection of event-triggered parameters is established. Case studies on a three-area test system illustrate the effectiveness and efficiency of our method. |
