چکیده
|
The paper presents the concept of wind power generation system inverter as saf under balanced and un-balanced conditions. pv based systems are practically inactive during the night time,because of the system cannot conserve the energy on the night time. during the night time,the pv-saf provides only the compensation for the reactive power disturbance through the battery bank. the reference currents extract by the fuzzy logic controller based instantaneous active and reactive power (p-q) strategy. when the supply voltages are balanced and sinusoidal,then all controllers converge to the same compensation characteristics. however,when the supply voltages are distorted and/or un-balanced sinusoidal,these control strategies result in different degrees of compensation in harmonics. the p-q control strategy with pi controller is unable to yield an adequate solution when source voltages are not ideal. extensive simulations were carried out; simulations were performed with balance,unbalanced and non sinusoidal conditions. simulation results validate the dynamic behavior of fuzzy logic controller over pi controller.
