A New Maximum Power Point Tracking Based on Neural Networks and Incremental Conductance for Wind Energy Conversion System

Abstract

This work presents a new Maximum Power Point Tracking (MPPT) for the connection of the wind turbine system (WT) to the synchronous permanent magnet generator (PMSG). To search the maximum power of the wind turbine, we have proposed a new MPPT which combines two techniques: Artificial Neural Network (ANN) and incremental conductance (IncCond) method. The advantage of ANN-based WT model method is the fast MPP approximation base on the ability of ANN according the parameters of WT that used. The advantage of IncCond method is the ability to search the exactly MPP based on the feedback voltage. In our case the ANN is employed to predict the maximum voltage of the WT, under different values of wind speed, and the control of DC–DC boost converter operation is executed by applying incremental conductance (IncCond) technique. The proposed system includes a wind turbine associated to a permanent magnet synchronous generator (PMSG), a rectifier and a DC-DC converter with MPPT control. The proposed algorithm is tested under MATLAB SIMULINK.

Wind Energy Conversion Systems Based on a Synchronous Generator: Comparative Review of Control Methods and Performance

“…A unique INC technique known as fractional order INC (FO-INC) was introduced to address the issue of instability. To reduce excessive power losses, the MPPT is tracked using a variable step size for rapidly changing feasible wind conditions [55][56][57]. Table 4 highlights the advantages and the disadvantages of the previously discussed MPPT techniques.…”

Control inteligente para optimizar la extracción de potencia y reducir vibraciones en sistemas eólicos offshore

“…Por otra parte, enfatizando en las redes neuronales (NN), numerosos trabajos también aplican este enfoque (Karthik et al, 2020), (Raouf et al, 2023). Por mencionar casos específicos, en (Muñoz-Palomeque, et al, 2023) una red neuronal de base radial (RBNN) es aplicada en la regulación del torque del generador para alcanzar la velocidad requerida del sistema eólico; en (Chandrasekaran, et al, 2020) el control de la extracción de máxima potencia es solventado con una NN en cascada, o en (Tidhaf, 2022) una NN es combinada con el método de conductancia incremental para el control MPPT En este artículo, se hace uso de un controlador híbrido para operar en la región MPPT de un aerogenerador flotante de 5MW. El esquema de control directo de velocidad (DSC) es utilizado como el medio de cálculo de la velocidad referencial del generador.…”
