Abstract: Aqua farms necessitate a constant power supply to run three-phase induction motors and sustain optimal oxygen levels. However, numerous regions face frequent power interruptions and are limited to a single-phase supply. Consequently, it is essential to convert singlephase power into three-phase power to operate the motors and utilize diesel generators during power failures. Unfortunately, the substantial consumption of diesel fuel presents challenges in aquaculture. To mitigate diesel usage, the incorporation of a photovoltaic (PV) and wind generator system within the aqua farm can prove advantageous. Nevertheless, both wind and solar energy rely on natural conditions and can be erratic. Therefore, a compact battery is also integrated into the system. An effective energy management system is vital to enhance the performance and cost-efficiency of the entire system. The battery is employed during transient periods and can be charged using PV and wind energy. Any surplus energy produced by the wind and PV systems can be fed into the single-phase grid, thereby lowering electricity expenses. DC to DC converters based on sliding mode controllers are integrated to ensure a stable DC-link voltage. The power sourced from the single-phase grid is converted to DC and subsequently elevated to the rated voltage to achieve adequate three-phase AC voltage via an inverter. This inverter output can be utilized to power motor-pump sets for water supply and three-phase induction motors for oxygen circulation in ponds. It is crucial to employ pumps to extract water from underground sources for various applications, including field irrigation and drinking water in aquaculture farms. The main goal of the proposed 10|Page controller is to reduce fluctuations in motor torque, thereby extending the lifespan of system components and decreasing power consumption. To accomplish this, a TS-Fuzzy based speed sensorless direct torque controller is utilized to operate an induction motor through a three-phase inverter. The performance of the proposed system is comprehensively assessed using the MATLAB Simulink platform, and the findings are presented to demonstrate its effectiveness in both steady-state and transient scenarios.
