Solar photovoltaic-integrated energy storage system with a power electronic interface for operating a brushless DC drive-coupled agricultural load

Abstract

Abstract This article describes the design and construction of a solar photovoltaic (SPV)-integrated energy storage system with a power electronics interface (PEI) for operating a Brushless DC (BLDC) drive coupled to agricultural loads. The proposed system is intended to make use of the electrical power available at under-utilized, pre-installed solar pumps used for irrigation. The PEI allows efficient energy management by charging and discharging depending on available solar power. The BLDC drive is a high-performance motor drive that requires a smooth and stable DC voltage. The bidirectional DC converter provides this while also allowing for efficient energy management between the battery and the solar PV system. The simulation results illustrate that the system is capable of efficiently managing energy between the battery and solar panels, providing a stable DC voltage to drive the BLDC motor. In addition to this, the results demonstrate the feasibility of integrating a solar system with a battery and BDC for driving BLDC in various agricultural applications. The experimental findings validate the simulation outcomes for the proposed setup implemented in pre-installed, untapped SPV systems. The system is able to provide a stable and efficient power source while also allowing for efficient energy management and utilization of solar energy.
