SMART SOLAR-POWERED WATER PUMPING SYSTEM WITH ENERGY STORAGE AND BIDIRECTIONAL POWER FLOW MECHANISM

This study describes a smart solar water pumping system that uses an induction motor drive and has grid-interactive characteristics. Solar PVs (SPV) may power up the irrigation and agricultural loads, reducing the load on the electrical grid. In addition to supplying the rated water discharge, the system is made to feed excess electricity back into the grid. By keeping an eye on the SPV array's power output, the maximum power (MPP) point is reached, guaranteeing optimal use of the device. The system operates in four distinct modes, and a universal control for each mode is suggested. The pump is guaranteed to run continuously even if the grid is not there. The motor that drives the induction motor is a variable frequency inverter (VSI). Additionally, the suggested system uses a voltage source converter (VSC) to enable bidirectional power transmission. The MATLAB/Simulink model of the system shows how well the suggested system integrates the SPV source into the grid, as do the simulated results.
