Development of generator aggregation technique for power system

Abstract

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 location in transmission lines are proposed in this paper. The generator aggregation is extracted from the model 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 a simple power system. Three generators and four buses are modeled in this study. This technique is implemented in MATLAB and the performance is tested based on the variation in the voltage profile. Results show that the voltage profile gets stable faster in the aggregated mode, compared to the original condition of the system.
