Abstract: Load frequency control (LFC) of an interconnected three-area power system with HVDC link under deregulated environment in presence of wind system is investigated. Integration of renewable sources in to exiting plants will affect the system frequency and hence design of a suitable controller is needed to maintain frequency within limits. Study of impact of wind penetration in to deregulated environment is a key factor. The secondary PID controller improves the overall system performance during sudden load disturbances and random variations of wind input. The optimal values of PID controllers in all three areas and pitch control in wind system are tuned by using Differential Evaluation (DE) algorithm.
