This critical period occurs when generator experiences a condition of lossing synchronization and is known as critical time. The smartgrid system, currently becoming a trend, requires dynamic optimization and realtime measurement techniques, so that, it can improve system reliability and asset management. In this study, the researcher modifies critical trajectory method to obtain a critical period of smartgrid system. Simulations are carried out using the Anderson 9-bus Fouad and IEEE 30-bus test systems. The results indicate that the proposed method can more quickly solve calculations compared to conventional methods. Some of our results are not intuitive.} }
