Modified Whale Optimization Algorithm for Solar Cell and PV Module Parameter Identification

Algorithm 1

MWOA.

	Initialize the whale’s population X;
	Calculate the fitness of each search agent;
	Leader_pos = the best search agent;
	while (t < maximum number of iterations)
	for each search agent
	Update a, A, C, l and ;
	if ()
	if (|A| < 1)
	Update the position of the current search agent by equation (10);
	else if (|A| ≥ 1)
	Update the position of the current agent by equation (16);
	end if
	else if ()
	Update the position of the current search agent by equation (14);
	end if
	Carry on the Levy flight for each agents using equation (25);
	end for
	Using pattern search to the best agent Leader_pos;
	Check if any search agent goes beyond the search space and amend it;
	Calculate the fitness of each search agent;
	Update Leader_pos if there is a better solution;
	t = t + 1;
	end while
	return Leader_pos;
