Voltage Stability Using STATCOM During Sudden Increase in Load Demand

Modern power systems are highly complex and are expected to fulfill the growing demands of power wherever required, with acceptable quality and costs. In the Electrical power system area, an exciting opportunity called Custom Power enables at-the-fence solutions for delivery to industrial and commercial customers, value added reliable electric service distortions, and over-voltages. It is now well known that voltage reductions of greater than 15 or 20% and of duration greater than a few cycles lead to significant losses for the increasingly automated processing and manufacturing industry. Sudden increase in load always creates voltage fluctuation. This paper investigates the effect of sudden increase in load with and without STATCOM.
