Fuzzy logic MPPT control for a solar PV module applied to water pumping

Abstract

Abstract:In this paper, the fuzzy logic control for maximum power point tracking (MPPT) of a solar photovoltaic (PV) module in water pumping application is presented. A PV system including a solar module, a DC/DC boost converter, a fuzzy MPP tracker and a resistive load is modelled and simulated for various atmospheric conditions. The P-V and I-V characteristics are first obtained for various values of solar irradiation and temperature. Also, the increased efficiency of the photovoltaic system using MPPT is computed and plotted. The fuzzy control method is compared with the perturb and observe (P&O) method in one hand and with an improved P&O technique using artificial neural network (ANN) in the other. The fuzzy MPP tracker is then applied to the water pumping system composed of a solar panel, DC/DC boost converter, DC/AC inverter, induction motor and centrifugal pump.Keywords: photovoltaic modules; DC/DC boost converter; maximum power point tracking; MPPT; fuzzy logic; perturb and observe; P&O; water pumping system.

Improved Artificial Neural Network Design for MPPT Grid-Connected Photovoltaic Systems

“…A photovoltaic module [35], a DC-DC BOOST converter [28][29][30][31][32][33][34][35], an MPPT controller [35], and a load make up a PV system [35][36][37]. The PVS system is depicted in diagram form in Figure 1.…”

“…Figure 3, displays the electrical circuit of a boost converter [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]: This type of converter can be used as an adapter Sourceload when the load needs a higher voltage than that of the photovoltaic system generator [9-31-39]. Through changing the duty cycle D, it is possible to adapt the source to the load [16].…”

Enhancement of Photovoltaic Pressurized Irrigation System Based on Hybrid Kalman Fuzzy

“…Other researchers have developed MPPT using Cuk [12], Landsman [13], and Zeta DC converters which are controlled by the International Journal of Intelligent Engineering and Systems, Vol. 15 PV output power at k th iterations incremental conductance (INC) method [14]. The disadvantage of conventional INC control in these studies is the relatively large oscillation in the MPP.…”

“…The disadvantage of conventional INC control in these studies is the relatively large oscillation in the MPP. Some researchers apply fuzzy logic controller (FLC) to photovoltaic water pump systems with a fixed hydraulic load, namely lifting water to a reservoir at a fixed height [15]. The method still has significant oscillations during the transition which causes the pump speed to oscillate.…”
