Effect of PWTS and AHVDC link on Multi-Area AGC System Considering TIDD Controller

This article presents the effect of a precise wind turbine system (PWTS) and accurate model of HVDC link on multi-area AGC systems. The proposed system comprises one thermal and PWTS unit in all the areas. A novel secondary controller known as tilt-integral-double derivative (TIDD) has been developed. In order to fine-tune the controller and other variables, the bird swarm algorithm (BSA) has been used effectively. The comparison of system dynamics responses with PID, TID, and TIDD controller concluded that the system with TIDD outperformed. The study of PWTS integration on system dynamics concluded that PWTS improves the system’s dynamic performance. Moreover, the integration AHVDC link with AC tie-line revealed significantly improved in dynamics responses. Further, the sensitivity analysis has been performed to test the proposed TIDD controller’s robustness under different loading conditions.
