Table 5

Comparative analysis with the existing systems.

Reference	Configuration	Controller	Peak overshoot			Settling time
			ΔF1	ΔF2	ΔPtie	ΔF1 in Hz	ΔF2 in Hz	ΔPtie in p.u.MW
[19]	Two areas nonreheat thermal power system	DE-based 2DOF-PID regulator	0.0144	0.00598	0.00711	11.1	7.2	13.8
[20]	Two area nonreheat thermal power system	ACO-based PID regulator	1.1 × 10^−6	0.0002	0.0001	29.62	37.20	50.41
[26]	Two areas reheat thermal, hydro, gas, and nuclear power plant	TLBO-based AGC system with output feedback SMC	0.0016	4.301 × 10^−4	8.050 × 10^−5	1.52	1.54	1,24
[22]	Two areas reheat thermal, hydro, gas, and nuclear power plant	LUS-TLBO-based fuzzy PID controller	0.000551	0.000219	0.0000826	5.26	2.96	2.36
Proposed	Two areas thermal-hydro	PDFF with FPA	20.5	18.6	35.7	0.239	0.147	0.054

The significance of the bold values given in Table 5 is that in the proposed method, settling time is much less when compared to other conventional systems.
