摘要
This paper presents an innovative formulation and implementation for the steepest descent method to minimize the current and voltage fluctuation in power systems. The steepest decent is selected because of its mathematical simplicity. Its main disadvantage is circumvented by proposing a technique that selects proper initial values in order to guarantee its convergence. This technique depends on the Yule-Walker equation. The suggested technique for disturbance extraction is utilized to operate a power conditioner in order to mitigate the current fluctuation, and its performance is compared with the output of the vector control that is commonly used for the mitigation of the current and voltage fluctuation. The presented ideas are conveyed and approved through simulation results using Malab/Simulink. Moreover, some experimental results are provided to affirm the practicality of the presented concepts.
