The induction motor drive can find widespread application in water pumping applications, particularly those that need for improved control in order to achieve higher levels of performance. In light of this, the study puts forth the idea of integrating a solar photovoltaic (SPV) water pumping system with a single- phase distribution system through the application of an induction motor drive (IMD) that incorporates a multi- mode power sharing concept. For the purpose of transferring power from the SPV to the IMD, a DC-DC boost converter serves not only as a grid interface device but also as a power factor correction unit. It is vital to extract the maximum amount of power from the SPV array in order to ensure good use of the SPV array. An incremental conductance-based maximum power point tracking control has been designed so that this objective can be fulfilled.
The suggested device has a controlling circuit that makes use of the fuzzy logic and fuzzy tuned PI controller. This circuit has the ability to effectively minimize the harmonics of the waveforms in three different modes. This has been contrasted with the scenario involving the PI controller, and performance was evaluated based on the waveforms produced by the system. The proposed topology is created and evaluated with the help of MATLAB/Simulink in three different modes: standalone, grid interfaced, and mixed mode. These modes represent different types of operational conditions.
