Transient stability improvement using allocation power generation methods based on moment inertia

Stability is an important issue in the operation of electrical power systems. Transient stability is a study that discusses the state of a power system after a major and rapid disturbance. In this paper, we offer a method to improve the condition of transient system stability. The critical clearing time (CCT) of the system can be increased by rescheduling the power generation based on inertia moment value. Changes in CCT values due to load changes on each bus were also observed. We used WSCC 9 bus system as the test case. The simulation shows that the value of CCT can be significantly improved by rescheduling the active power generation based on inertia moment value.
