Coordinated Power Management for Speed Control of BLDC Motor Powered by wind-Battery-PV for water Pumping Applications

The provision of water through underground sources using pumps is essential for sustaining human life. water pumping systems driven by electrical motor that Powered by standalone hybrid renewable energy sources are becoming famous worldwide due to their special features and applications. In order to reduce consumption from utility grid, the hybrid standalone Power supply system must be designed in a proper way to make a continuous water supply to consumers. Solar Photovoltaic systems (SPSs) and wind Power Systems (/PSs) are the two most abundant sources of renewable energy globally. Depending exclusively on the integration of SPS and wPS may not ensure a consistent energy supply, given their reliance on natural elements and susceptibility to variables like solar irradiance at night or overcast conditions. In order to tackle this problem, incorporating batteries can improve the system's dependability and ensure a consistent Power source for the motor that can operate the water pump. Many places including apartments, over head tanks etc facilitating with plenty of free space that areas can accommodate the installation of hybrid SPS, batteries and wPS. Nevertheless, a successful operation necessitates a well-coordinated energy management system involving the SPS, wPS, battery, motor, and pump. The paper suggests the implementation of a centralized energy management system of proposed water pumping system. To obtain effective operation, a Brushless DC Motor (BLDCM) is considered and designed an efficient control methodology in this paper. Each Power production units is equipped with their corresponding maximum Power point tracker (MPPT) circuits to obtain highest efficiency. A shared dc-link is created by interconnecting all MPPTs and the battery bank using a DC bidirectional circuit. The suggested approach has been confirmed through thorough results acquired from HIL experiments carried out utilizing OPAL-RT units.
