This paper proposes a new approach to control a Shunt active filter (SAF) to
eliminate harmonic currents and compensate reactive power , this approach called
Predictive Direct Power Control (P-DPC) where the Direct Power Control is combined
with a
Predictive Control , PDC controls active and reactive power to get an unity power
factor and when it combined with Predictive Control , the controller can predict future
behavior for all possible voltage vectors , and the best vector is chosen for the next sample
by minimizing a cost function . we connect this filter with a nonlinear load to the grid and
simulate this systemusing Matlab , Simulink and Simpower , the results shows that P-DPC
decrease Total Harmonic Distortion (THD%) of line current and make it sinusoidal and
improve the power factor .
In this paper, we have suggested the STATCOM
(STATic synchronous COMpensator) to connect PV-solar (or
wind) frame to the power system for the Hassia industrial city
which we chose as a case study. This frame will provide the city
with the required power, improve the power quality and inject
the redundant to the power system.
