Design and Optimal Choice of a Photovoltaic Pumping System for Irrigation Purposes | Chapter 3 | Theory and Applications of Engineering Research Vol. 7

The global demand energy growth and the exhaustion of oil fields and conventional gases have promoted research in the field of renewable energies. Among these sources of energy, the solar is the most important renewable energy source in Morocco. The present project deals with a method of designing a photovoltaic solar pumping system. The aim of this design is to make an optimal choice of the various industrial equipment of this system as well as the choice of the appropriate numerical methods ensuring optimization, regulation and safety. This sizing method is based on the mathematical equations that govern the system as well as the charts of electrical and mechanical quantities. The system in question is composed of three equipments namely: The PV generator, the drive and the motor pump. This design not only makes it possible to design the pumping system to meet the desired technical specifications, but also to ensure compatibility to ensure proper operation and reliability. It is based essentially on the assessment of the water requirements, the calculation of the necessary hydraulic energy, the calculation of the necessary electrical energy that is provided by the PV generator and the optimization of the constituents of the system. In this design, the estimated flow is 3 m3 / h for a total dynamic head (TDH) of 75 m. The design and choice of the industrial equipment are made on a real installation to meet the water needs of the gardens of the Faculty of Science and Techniques of Beni-Mellal.

 

The theoretical sizing technique used guides and makes easier the optimal choice of the station’s equipment. A PV generator of six poly-crystalline modules ElySun250, the solar three-phase inverter HSPL 1500H and the motor pump SP3A-18T are chosen for our pumping station. They are compatible with voltage, current and electrical power. This is essential to ensure proper functioning and avoid any damage or destruction of the purchased system on the installation site.

Investigation on Electronically Coupled Distributed Generation Modeling and Control Strategies for Microgrid Applications| Chapter 2 | Current Topics on Mathematics and Computer Science Vol. 4

 A single-stage power converter capable of both maximum power point tracking and unity power factor dispatching is proposed for electronically coupled dispersed generation. Modeling a solar array (the dispersed generator) and a three-phase grid-connected inverter yields the best control parameters. Inner and outer control loops are used by the inverter's controller to control parameters. The inner control loop translates input from the abc frame to the d, q, 0 frame in order to dispatch at unity power factor. The new technique, which may be used at the primary control level in microgrid applications, tracks the maximum power point in the outside circuit. loop of voltage control (local controller). The active power of single-stage and two-stage power converters is compared, revealing that single-stage is more efficient. In terms of active power yields, a comparison is made between variable and fixed DC reference voltages for the proposed single-stage converter system. The impacts of diverse ambient disturbances on active and reactive power yields, such as changing weather conditions, solar radiation with severe disturbances, and varying PV cell temperature, are explored in this paper. this project A dynamic reference voltage is advised for use. Simulations in Matlab/Simulink demonstrate its efficiency under a variety of radiation and temperature settings. The single-stage power conversion system executes all duties correctly with a unity power factor operation.
