Abstract

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.
