摘要: This paper investigates the problem of load frequency control (LFC) for power systems with large delay periods (LDPs), which is often present in practical and makes them unstable. LFC LDPs has been modeled as switched systems, include an unstable subsystem caused by LDPs. The switching strategy used to deal stability criteria are proposed under constraint conditions length ratio LDP ensure exponential stable. Finally, relationship between gains PI controller margin studied simulation results show that method effective.
