A Self-Adjusting Adaptive AVR-LFC Scheme for Synchronous Generators

An efficient self-adjusting flexible metaheuristic is introduced to develop automatic voltage and load frequency regulation schemes for multi-area power system. It employs non-linear threshold accepting algorithm to find the best combinations of PID control gains using an innovative nonlinear search function. This approach outperformed well established heuristics and other conventional internal model control approaches in terms of the dynamic response, robustness in uncertain dynamical environments, and quality of the solutions.
