Performance-enhancing substances, also known as performance-enhancing drugs (ped), are substances that are used to improve any form of activity performance in humans a well-known example involves doping in sport , where banned physical performance–enhancing drugs are used by athletes and bodybuilders. To suppress these oscillations and maintain power system dynamic performance, one of the conventional, economical and effective solutions is to install a power system stabilizer (pss) however, in some cases pss may not provide sufficient damping for the inter-area oscillations in a multi-machine power system. Stability enhancement of multi machine system using a unified power flow controller mmanikanta prasad1, mravindrababu2 mtech (hve), dept of eee, jntuk this model can be used to examine the effect of small-signal disturbance on the eigen values of the multi-machine power system when a pss or any facts devices are installed at any.
