| Summary: | This paper aims at improving the power quality with
controlling method shunt active power filter in Micro-
grid System. A hybrid compensation system consisting of
an active filter and passive filters in the Micro-grid is
discussed. Passive filter is connected to a distortion
source and designed to eliminate main harmonics and
supply reactive power for the distortion source, while the
active filter is applied to the correction of the unbalance
condition a system and cancellation of the remaining
harmonics. In order to examine the proposed method,
simulations are carried out in the case of the distribution
system with dynamic nonlinear loads and Micro turbine.
Several dynamic nonlinear loads without any filters using
just shunt active filter, passive filter and the proposed
hybrid structure. The performance of the proposed system
was analyzed and simulated via MATLAB software. The
results confirm the validity of the proposed approach to
eliminate undesired harmonic and distortion.
