SummaryThis article proposes a hybrid POA‐RBFNN approach for PV (photovoltaic) based grid tied intelligent controlled water pump system. The proposed method is the hybrid wrapper of Pelican Optimization Algorithm (POA) and Radial Basis Function Neural Network (RBFNN) and later it is termed as POA‐RBFNN method. On the basis of bidirectional power grids, this research presents bidirectional power flow control for PV systems. The water pump is driven through a three‐phase synchronous reluctance motor (RSM). A novel Cuk integrated Landsman converter can operate at low duty cycles to provide larger DC voltages with negligible switching losses is used. In addition, to enhance the pumping system reliability, solar panels and electric pumps can be used to their maximum potential. Despite fluctuating weather conditions, the system supplies nominal displacement all over the day and surplus energy to the grid. Furthermore, if one of the sources fails, the pump performance is unaffected. Switching losses are minimized since the Voltage Source Inverter (VSI) operates at a fundamental frequency. In all operational modes, this control delivers unique grid‐side power quality and unity power factor functioning. Here, the performance of the proposed hybrid system is implemented in the MATLAB and is compared with several existing methods.

Two-level inverters are the most basic kind of multi-level inverter (MLIs). Total harmonic distortion diminishes as the number of output levels is increased. In classic MLI topologies, more electronic components are utilized to get higher-level outputs, which raises the cost, complexity, and volume of typical MLI installations. By reducing the use of power components, overall costs can be reduced. Further, the two and three-level inverters produce constant dv/dt output, which increases the stress on the power switches. This research proposed an asymmetric MLI topology that is suitable for PV applications and utilizes a minimum number of components. A selective harmonic elimination-based pulse width modulation (SHEPWM) is implemented for the proposed inverter to eliminate the lower-order dominant harmonics. The non-linear transcendental equations produced by the SHEPWM are solved for the switching angles of the proposed inverter using the Newton-Raphson approach. The performance of the inverter is analyzed based on the THD of output for different operating levels of the inverter. In this research, the NR method yielded a THD of 7.3% at a 0.9 modulation index. Also, the proposed inverter is applied to grid-connected solar PV systems for the analysis of THD.T The THD of the grid voltage is measured as 0.06% and the THD of the grid current is 4.8% with the proposed inverter which is acceptable as per the IEEE519 standards.

“…In addition, because of the variation in high frequency, the total harmonic distortion (THD) of the stator current will increase forward [8]. In order to attenuate these waves, multilevel inverters, also known as MLIs, are used [9]. It was stated that there is a space vector pulse width modulation that may reduce ripples in flux and torque [10].…”

Because water extraction from wells accounts for the bulk of energy consumption in irrigation operations globally, the sustainability and profitability of irrigation are strongly reliant on the energy efficiency of the pumping system. A technique that studies and improves the performance of motors used in well pumping systems is reported in this body of research as having been undertaken. In a similar manner, an experimental investigation of the energy efficiency of two modern systems of induction motor control has been carried out. According to the results, proper control performance is critical to achieving improvements in energy and efficiency. Using DTC-SVM for IM, the purpose of this study is to demonstrate a prototype of a pumping system that is powered by solar energy in the presence of changing radiation levels. Real-time MATLAB/Simulink simulations are used in conjunction with a dSpace 1104 board to carry out the hardware implementation.
