Power Flow Simulation of a 6-Bus Wind Connected System and Voltage Stability Analysis by Using STATCOM

Flexible AC Transmission System Device (FACTS); Participation Factor; Static Synchronous Compensator (STATCOM); Eigen Values.

FACTS devices have become significant tools for power flow study now-a-days. It has widely improved the power system reliability, operation capability and safety. It has also improved the robust control of power system. FACTS devices are generally made of power electronics devices and circuits. That’s why FACTS devices have appeared as the most outstanding innovation in the era of power electronics and power system. FACTS devices are of many types: TCSC, SVC, UPFC, IPFC, STATCOM etc. Among all the devices STATCOM has become one of the most important power system components for reactive compensation of power and Voltage stabilizing capability. In this paper we have a 6 BUS power system with a variable speed wind generator connected to a BUS. For the stochastic nature of the wind the BUS voltage becomes degraded. With the help of STATCOM, corresponding BUS voltage has been improved significantly which has been studied and simulated in our paper. We have simulated the whole system with MATLAB PSAT environment and analyzed the voltage response, rotor angle response, eigen values, participation factor etc.
