An FRLQG Controller-Based Small-Signal Stability Enhancement of Hybrid Microgrid Using the BCSSO Algorithm

Algorithm 1

Bell-curved squirrel search optimization (BCSSO) algorithm.

	Input: parameters (t) and Y (t)
	Output: optimal parameters
	Begin
	Initialize location ηij = (ηi1, ηi2, ηi3……….ηid) seasonal constants and maximum
	Iteration Maxu
	Define initial location of each flying squirrel by, ψij = ψl + Bs  (ψu − ψl)
	Calculate fitness function
	Set iteration IIt = 1
	While (IIt ≤ Maxit) do
	Generate locations using 3 locations
	Scenario 1:
	If (r1 ≥ ppp); {
	Update the squirrel location
	} else {
	}
	end if
	Scenario 2
	If (r2 ≥ ppp); {
	Update the squirrel location
	} else {
	}
	end if
	Scenario 3
	If (r3 ≥ ppp); {
	Update the squirrel location
	} else {
	}
	end if
	Perform seasonal monitoring by using a seasonal constant
	Calculate fitness function
	Set IIt = IIt + 1
	End while
	Return optimal parameters
