Design of a Robust Coordinated Power Oscillation Damper for Use with Large-Scale Wind Energy System Connected to a Multimachine Power System

Algorithm 1

Pseudocode for the hybrid GWO-PSO.

	Initialization of the population Xi (i = 1, 2, …, n)
	Initialization of GWO-PSO parameters, i.e., (a, A, C, )
	Calculation of fitness for each wolf in the population
	The top three individual wolves with the highest fitness are recorded as , and respectively
	While (i < maximum iteration)
	For each wolf
	The position of the current individual is updated based on PSO using (29) and (30)
	End for
	The values for a, A, and C are updated
	The fitness value of all individuals is calculated
	, and is updated
	i = i  +  1
	End While
	The position of the alpha wolf, , is returned
