Optimization of a photovoltaic pumping system

Abstract Renewable and clean energy is the guarantee of the continuation of practical life on earth and the preservation of the environment because fossil energy becomes difficult to obtain over time and its resources are limited.Inthis article, solar energy is used as a source of energy production, but the conversion efficiency of this energy is low so we used methods to ameliorate the stability and efficiency of the system such as the differential evolution (DE) algorithm and direct torque control with an intelligent speed regulator based on the particle swarm optimization algorithm, these optimization techniques have proven their characteristics in terms of stability and efficiency of the photovoltaic pumping system which needs to be developed particularly in remote areas where there is no electricity.
