Development of generator aggregation technique for power system

Abstract

Generator Aggregation is a technique for power system and this technique is important for analyzing because this method practically ignores the control system that exists in the generator system. Classical aggregation is still able to provide a good approximation on the stability of the system. .The theory of generator aggregation in transmission line systems based on faults and variation of voltage is presented. Voltage and frequency will very when a fault occurs in the power system. Fault study can be simplified by using the generators aggregation. Inertia aggregation techniques which are based on for assessment processing, to locate the location in transmission lines, are proposed in this thesis. The generator aggregation is extracted from the modal stability of voltages at the single and multi machines of the power system network. The technique identifies the fault by using the information contained in the system. 3 generators and 4 buses are modeled in the analyzing to the study. This technique is implemented in MATLAB and the performance is tested on the variation of simulation such as the model aggregated stability of voltage is faster than non aggregated.
