Load frequency control is one of the most important frequency management mechanisms in the modern power system (LFC). One of the unavoidable issues associated with LFC over a large area is communication delay. The delay may reduce system performance and cause system instability. This study proposes an alternative design approach for creating delay compensators for LFC in one or more control zones. A sufficient and required condition for designing a delay compensator for one-area LFC is stated. It is demonstrated that for multi-area LFC with area control errors (ACEs), if the index of coupling among the areas is less than the cutoff value established by the small gain theorem, each control area can have its own delay controller as in a one-area system. To demonstrate the effectiveness of the proposed technique, simulation studies on LFCs with communication delays in one interconnected area and multiple interconnected areas with and without time varying delays are used.
