Abstract :
This paper presents a comparison analysis among some methodologies in which aims to solve the selection of pilot buses for Secondary Voltage Control. For this purpose, a brief review of methodologies for both identifying voltage control areas and pilot buses selection are described. The validation of the results is done through the standard deviation applied to the variation of the voltage magnitude of the system buses before and after a given disturbance, reactive power generation and active power transmission losses. In this paper, the disturbance is the application of a load curve applied in reactive power demand of the load buses consists of 168 load levels. Results are presented using the well known IEEE 118 buses system.
