PV array Control for MPPT Power Generation Under Partial Shading

The aim of this paper is to use an intelligent method for the Maximum Power Point Tracking (MPPT) of a photovoltaic (PV) generation system under partial shading conditions. In fact, the MPPT is achieved by using the intelligent algorithm for finding the global maximum power point. This algorithm combines a traditional MPPT technique (perturb and observe (P&O)) with an artificial neural network (ANN) method. The main goal of this algorithm is to predict the global maximum power point. simulation results show the effectiveness of the algorithm under partial shading conditions.Le but de cet article est d'utiliser une méthode intelligente pour le suivi du Point à puissance maximale (MPPT) d’un système photovoltaïque (PV) soumis à des conditions d'ombrage partiel. Effectivement, Le MPPT est achevé en utilisant l'algorithme intelligent pour trouver le point de puissance maximale global. Cet algorithme combine une traditionnelle technique pour le fonctionnement en MPPT (P & O) avec un réseau neuronal artificiel (ANN). Le but principal de cet algorithme est la prédiction du point à maximum de puissance. Les résultats de simulation obtenus montrent l’efficacité de cet algorithme

Comparative study of back-stepping controller and super twisting sliding mode controller for indirect power control of wind generator

© 2021 Springer. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1007/s13198-019-00905-7This paper presents the application nonlinear control to regulate the rotor currents and control the active and reactive powers generated by the Doubly Fed Induction Generator used in the Wind Energy Conversion System (WECS). The proposed control strategies are based on Lyapunov stability theory and include back-stepping control (BSC) and super-twisting sliding mode control. The overall WECS model and control scheme are developed in MATLAB/Simulink and the simulation results have shown that the BSC leads to superior performance and improved transient response as compared to the STSMC controller.Peer reviewe
