optimization of Sliding Mode Control based on BAT-Algorithm for the DFIG-WT

Abstract

This topic presents a rotor-branch current control (RBC) regarding stator-branch power conduct based on an optimal sliding surface of Sliding Model (SMC) using BAT-Algorithm (BS-SMC) for the grid-tied Doubly-Fed Induction Generator type that connected with wind turbine (DFIG-WT). The BS-SMC is built to regulate the DFIG system in a dq-reference stage rotor-branch current during many operation scenarios to meet the dynamic factors. The simulated BS-SMC test results for a 1. 5MW DFIG-WT are robust to gave a superior dynamic action i.e lowest than 10% overshoot of rotor-branch current and stator-branch power and other dynamic characteristics than common controllers. Furthermore, BAT algorithm enhanced the global searching and the convergence less 10e–4 in tolerance region during iterations.
