Optimal Fractional Order Based on Fuzzy Control Scheme for Wind Farm Voltage Control with Reactive Power Compensation

Table 2

Fuzzy logic rules for voltage controller.

I^λ (e)	e
	PB	PM	EZ	NB	NB
PB	PB	PB	PM	PM	EZ
PM	PB	PM	PM	EZ	NB
EZ	PB	PM	EZ	NM	NB
NM	PM	EZ	NM	NM	NB
NB	EZ	NM	NM	NB	NB

NB is negative big, NM is negative medium, EZ is equal zero, PM is positive medium, and PB is positive big.
