A New Optimum Frequency Controller of Hybrid Pumping System: Bond Graph Modeling-Simulation and Practice with ARDUINO Board

Abstract

Abstract-The strategy of rural development in Tunisia needs to include as one of its priorities: the control of water. In seeking solutions for the energy control dedicated to pumping, it seems interesting to know the benefits of a new technique based on the complementarities of two renewable energy sources such as solar and wind power. The climate's dependence requires a complex modelling and more optimization methods for controlling of hybrid system. Moreover, in recent years, technological progression at hardware and software enables researchers to process these optimization problems using embedded platforms. For this paper, we apply the approach bond graph to model a complex system. Our hybrid pumping installation contains a photovoltaic generator, a wind source, converters and an induction motor-pump group. The numerical closed-loop simulation of the complete model in an appropriate environment allows us to generate an optimisation control whose the appropriate frequency depends on meteorological conditions (wind speed, insulation and temperature). The implementation of this control and the experimental measurements validate the optimum efficiency and verify operation reliability of our hybrid structure.

Energy Management Strategy of a PV/Fuel Cell/Supercapacitor Hybrid Source Feeding an off-Grid Pumping Station

“…By controlling the speed of the machine, we are controlling the flow rate of the water pumped by the moto-pump set [21]. Table 4 contains different technical specifications of both speed drive and moto-pump in study.…”

“…Based on this electrical scheme, the different voltages can be expressed in (10) and the relation between the input and the three output currents is given by (11) [22]. …”

“…The fact that the centrifugal pump presents a proportional relation between its resistive torque and the square of its speed, we can write the total electromagnetic torque of the moto-pump by replacing the new expression of T L in (21) and finally obtain (21) …”

Studying the Influence of Static Converters’ Current Harmonics on a PEM Fuel Cell using Bond Graph Modeling Technique

“…Among these approaches, we chose to use a graphical technique which is the Bond Graph (BG) modeling technique in order to simulate the dynamic behavior of the system [6], [7]. The benefit of this approach is that a complex electrical system for example can be designed as different subsystems, where each one presents one part of the real system, and then make the connection between the ports of these different subsystems in a form of bonds which describe the transfer of energy between the real parts of the system [8], [9].…”
