The modern power system is becoming more susceptible to electromechanical oscillations and potential stability issues due to the fast-rising rate of variable, low-inertia power sources and unexpected operating conditions. An electromechanical oscillation (EMO) index can be used by control center system operators to obtain operational situational awareness (OpSA) on the stability of the system and to alert them on any potential risks. The benefits of an EMO index based on the integration of frequency response analysis (FRA) and time response analysis (TRA) of EMOs using fuzzy logic is utilized in this paper to assess the system stability for different generation and loading conditions. The OpSA can be utilized by system operators to re-dispatch generation in order to improve and/or maintain overall system stability. Typical results to illustrate the utilization of OpSA for system stability enhancement by system operators is presented on a modified two-area four-machine power system with two solar photovoltaic plants.
