“…The apropos literature has witnessed various works on the novel controller design. Some of the recently published literature incorporates PI/PID structured controllers are dragonfly search algorithm [11], bacterial foraging optimization algorithm (BFOA) [12], particle swarm optimization (PSO) and hybrid BFOA (PSO-hBFOA) algorithm [13], lozi map-based chaotic algorithm [14], firefly algorithm tuned PI controller [15], PIDD2 control approach [16], ant colony optimization for hydrothermal power plant [17], flower pollination algorithm tuned PI-PD cascade control [18], genetic algorithm (GA)/differential evolution (DE) [19], bat algorithm tuned PD-PID cascade control approach [20], improved stochastic fractal search (SFS) algorithm [21], sine cosine algorithm based PI controller [22], DE tuned PI/PID [23], biogeography based optimization tuned I/PI/PIDF [24], teaching learning based optimization algorithm based 2-degree of freedom (DOF) PID (2DOF-PID) [25], disrupted oppositional based gravitational search algorithmpattern search based PID [26], symbiotic organism search algorithm tuned PID [27], hybrid SFSlocal unimodal sampling (hSFS-LUS) based multistage PDF-(1+PI) [28] and imperialist competition algorithm tuned PID controller for PV-thermal and hydrothermal based interconnected power system [29]. A GA-based LFC scheme with the stability evaluation under solar, DG, and battery-based distributed energy sources is demonstrated in Ref.…”
