Abstract

Aqua farms necessitate an uninterrupted power supply in order to run three-phase induction motors and sustain optimal oxygen levels. Hence, it is necessary to convert single to three-phase power in order to operate the motors and use diesel generators during power outages. Unfortunately, heavy diesel consumption poses challenges in aqua culture. To address this, integrating a photovoltaic (PV) and wind generator system can help reduce diesel consumption. However, both wind and solar energy are dependent on nature and unpredictable. Therefore, a small-sized battery is also integrated into the system. An effective energy management system is essential for achieving a cost-efficient system with optimal performance. The battery is employed to respond during transitional time periods. The suggested energy management system has the capability to minimize diesel usage by operating at peak efficiency. The battery can be replenished from both PV and wind sources. Any surplus power from these sources can be transferred to the single-phase grid in order to decrease electricity expenses. DC to DC converters, based on sliding mode controllers, are integrated to uphold a steady DC-link voltage. The supply from the single-phase grid is converted to DC and then boosted to the rated voltage to obtain sufficient three-phase AC voltage through an inverter. The proposed controller aims to reduce ripples in motor torque, thereby improving the lifetime of system components and reducing power consumption. An induction motor is controlled using a TS-Fuzzy based speed sensorless direct torque controller and a three-phase inverter to reduce torque fluctuations. The performance of the proposed system is validated using the Hardware – in the – Loop (HIL) on OPAL-RT platform associated with MATLAB/Simulink, and the results are presented comprehensively to demonstrate its effectiveness in both steady state and transient conditions.
