A PSO-based Optimization of a fuzzy-based MPPT controller for a photovoltaic pumping system used for irrigation of greenhouses

The main asset of this paper is among the uses of fuzzy logic in the engineering sector and especially in the renewable energies as a large alternate of fossil energies, in this paper a PSO-based optimization is used to find the optimal scaling parameters, of a fuzzy logic-based MPPT controller, that maximize the efficiency of a photovoltaic pumping system. The tuning of input and output parame...

Experimental Results of Photovoltaic Powered Induction Motor Drive for Pumping

A pumping system powered from Photovoltaic array is modeled and simulated using Matlab Simulink. Detailed evaluation of energy processing in Photovoltaic pumping system is presented. A low voltage DC is stepped by using DC to DC Push -Pull converter. DC output from the PV Cell is converted into high frequency AC using a Push Pull Inverter. This is stepped up to 200v using a high frequency steps...

Modern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant

Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...
