Abstract
Renewable energy is a cheap, clean and abundant source of energy that can be used to feed isolated loads as well as grid connected ones. Wind energy and tidal energy are two popular forms of renewable energy. The variation of output power with the continuous variation of tides or wind speed can cause significant power quality issues. This paper studies a network presenting a rural load, such as a small village, fed from a hybrid wind/tidal turbines that are connected to a weak grid. The effect of the variation in tides and wind speed on the power quality is illustrated via simulation. The introduction of the Modulated Power Filter Compensator (MPFC) to the network establishes a significant improvement to the power quality. The proposed MPFC is a cheap and robust FACTS based device. It is controlled via a tri-loop dynamic error-driven PI controller. This scheme proved its ability to introduce a significant improvement which is illustrated via comparing the simulation results of the studied network with and without the MPFC.
