In this paper, the efficacy and value of using corrective control supported by transient assistive measures (TAM) is quantified in terms of the cost savings due to less constrained operation of the system. The example TAM is a rapid modulation of the power order of the high-voltage direct current (HVDC) links in the system so as to improve transient stability during corrective control. A sequential...
Through a mount of simulations of power system emergency control, it is confirmed that action time of emergency control affects the transient stability of power system. This paper introduces control time component in the consideration of the existing emergency control model which is based on the dynamic security region(DSR). This paper quantifies the degree of system instability parameter after shedding...
This paper presents Generator Aggregation which is an important technique in power system analysis. This method relies on faults and variation of voltage in power transmission system. Voltage and frequency will vary when fault occurs in the power system. Fault study can be simplified by using generator aggregation. Inertia aggregation techniques which are based on processing assessment of the fault...
