Comparative Study of AVR Control Systems Considering a Novel Optimized PID-Based Model Reference Fractional Adaptive Controller

Voltage regulation is a crucial task for electrical grids in the presence of high penetration levels renewable energies. The generator excitation improves stability power system. An essential tool controlling generators automatic voltage regulator (AVR). It advised to use controller increase reliability an AVR. A survey about different types controllers proposed this paper. Then, novel optimized PID-Based model reference fractional adaptive proposed, with detailed mathematical modeling. was compared survey. proved its superiority over other through fast response and low rising settling times. Moreover, smoothly instantaneously tracked dynamic changes.
