Power system stability in wide area network is needed for providing optimal power flow. Though various developments in this regard have been proposed, the complexity and large wide inter connection has limited the stability in power system. The dynamic load conditions and variable power system has increased the stability constraint in power system. With a rapid increase in demanded power, existing power system is integrated with different power generation units, interconnected in multiple zones to supply the demanded power. Due to diverse power system interface, the issue of stability in power system has become critical. Power system stability over small signal is proposed here in the paper. The control design is developed for two area power system. A stability approach using a one-loop and two-loop control strategy in DFIG interface over two area network is developed. The Eigenvalue analysis is done for a two area power system without power system stabilizer and with power system stabilizer.
