“…This lack of consensus stems in part from the fact that the literature contains no comparisons of absolute efficiencies of MPPT algorithms, with all algorithms using optimized parameters and operating on a standardized MPPT hardware. Most of the reported comparisons are made between an MPPT algorithm and a directcoupled system 1,2 or between an MPPT algorithm and a converter designed for a fixed operating point. 3 Others report comparisons of one algorithm with another, but these generally compare an algorithm under test with fully optimized parameters against a baseline algorithm (usually P&O), the parameters of which are not described and appear not to be optimized.…”

Maximum power point trackers (MPPTs) play an important role in photovoltaic (PV) power systems because they maximize the power output from a PV system for a given set of conditions, and therefore maximize the array efficiency. Thus, an MPPT can minimize the overall system cost. MPPTs find and maintain operation at the maximum power point, using an MPPT algorithm. Many such algorithms have been proposed. However, one particular algorithm, the perturb-and-observe (P&O) method, claimed by many in the literature to be inferior to others, continues to be by far the most widely used method in commercial PV MPPTs. Part of the reason for this is that the published comparisons between methods do not include an experimental comparison between multiple algorithms with all algorithms optimized and a standardized MPPT hardware. This paper provides such a comparison. MPPT algorithm performance is quantified through the MPPT efficiency. In this work, results are obtained for three optimized algorithms, using a microprocessor-controlled MPPT operating from a PV array and also a PV array simulator. It is found that the P&O method, when properly optimized, can have MPPT efficiencies well in excess of 97%, and is highly competitive against other MPPT algorithms.

“…Other brushed dc motors such as series shunt and separately exited motors have also been investigated Koner (1995); Fam & Balachander (1988); Atlam & Kuyumcu (2003). In bore-hole and deep-well 194 pumping applications, induction motors Taha & Suresh (1996); Feraga & Bouldjedri (2016) and brushless dc motors Lawrance & Langridge, (1995); Jain, Sarkar & Siddique (2015) are preferred since they require less maintenance. Other types of motors have also been used including single-phase induction motors and switched reluctance motors Metwally & Anis (1995); Vongmanee (2004).…”

Nowadays, water pumping systems powered by solar-cell generators are one of the most important applications. It’s a promising alternative to conventional electricity and diesel based pumping systems, especially for applications like community water supplies and irrigation. This study presents a monitored standalone photovoltaic solar direct pumping system using the Maximum Power Point Tracking (MPPT) algorithm to optimize the solar photovoltaic conversion efficiency. It was done at ISET-Rosso in Mauritania. The experimental setup based on Lorentz PS1200C-SJ8-5 pumping system consists of four photovoltaic (PV) panels, inverter PS1200, BLDC motor, centrifugal pump and a storage tank. The system has been monitored, in order to determine the relationship between: the DC power produced by the PV generator and the solar radiation; the water flow and the DC power and by then the relationship between the water flow and the solar radiation. The effect of ambient temperature and solar radiation on the PV panels was also done under Matlab/Simulink environment and compared to the experimental results. ©2019. CBIORE-IJRED.

“…The drive system are applied to the conservative and the energy saving. One application is the water pumping system supplied by the photovoltaic arrays by different technical control [4,5,6,7,8,9,10] The characteristic of the photovoltaic arrays are exactly nonlinear that the power depended on light intensity change. A voltage from photovoltaic arrays is increased (decreased) follow light insolation.…”

The objective of this paper presents the Photovoltaic (PV) water pumping system with maximum power point tracking (MPPT) by using the optimum slip angle control of the three phase induction motor pump. A field oriented control principle is used in control by changing a magnetizing current (Ids) follow a torque producing current (Iqs) in equality ratio resulting to the ratio of currents are constant. The efficiency of the motor pump is better than the magnetizing current constant. An adjustment of the magnetizing current follows light insolation that means the magnetic flux of motor pump are controlled, so the coreloss are reduced. The experiment results prove the concept of the constant ratio control between Ids and Iqs in order to optimum slip that the efficient of the water pumping system supplied by the photovoltaic arrays are increased. The system consume the maximum power from PV every light intensity level.
