Abstract

Stability analysis in electrical power systems is based on the study, in dynamic state, of the voltage and frequency, because when there is some contingency it fluctuates drastically due to the primary and secondary controls of the voltage and frequency to the power systems that act on the generators. In order to solve the possible stability problems that may arise in power systems, various techniques have been developed that act on the generating machines for their protection, as well as on the loads for the power cut. The present resarch proposes an alterna-tive methodology for load disconnection by low frequency as an option to save the power system from a possible blackout due to instability caused by a fall in the frequency, managing to improve the results affected by other im-proved techniques, the frequency change range, frequency deviation and the effects of demand disconnection. The proposed methodology was tested in the IEEE 14 bus system.
