Hybrid Harmony Search Based D-TIF Controller for Load Frequency Control of Multi Area Power System

The focus of the current effort is load frequency control (LFC), which aims to supply consumers with high-quality power with little variation in frequency and tie line power. Strong intelligent control mechanisms have been used to fine-tune the parameters of the suggested derivative with tilt integral filter controller (D-TIF) in order to achieve this goal. An illustrative and practical solution for the LFC of two area-interconnected power systems is obtained using a novel optimization technique known as the hybrid harmony search differential evolution algorithm (HHSDE). Workable models for the investigated power systems include nonlinearities such generator rate limitations, boiler dynamics, and governor dead band (GDB). In comparison to other current traditional systems like the proportional-derivative-integral (PID) controller and the tilt-integral-derivative (TID) controller, the recommended D-TIF controllers are more resilient. In terms of peak overshoot, integral time square error (ITSE), and settling time, the preferred D-TIF controller provides a better dynamic response. By contrasting the HHSDE algorithm with other algorithms that have been reported in the literature, its efficacy is demonstrated. To test the HHSDE algorithm's capabilities, the robust and penetrative behaviour of the upset power system is also examined.
