Active and Reactive Power Control of DFIG Wind Power System by Heuristic Controllers

Abstract

Hitherto this paper presents around Active power along with Reactive power clout of a grid allied doubly fed Induction Generator (DFIG) with wind energy system (WES) employing PI & ANFIS controller and ALO (Ant lion Optimization) FOPI (Fraction Order PI) Controller. DFIG is adapted in d-q revolving allusion cage circuit with stator flux oriented, field oriented clout approach. By using a coterminous converter of Variable speed constant Frequency (VSCF) along with active the reactive power and DC tie voltage are controlled at sub and super synchronous speeds. A PI controller has been combined with an ANFIS controller in order to enhance the power controlling capability at steady state and voltage dip conditions and then the results are combined with FOPI controller tuned by a Heuristic Ant Lion Controller to strengthen the work of conventional PI controller. The Active and Reactive Powers can intensify further by casting with an MPPT arrangement depleted by using Cuckoo Search.
