Abstract: In view of the limited demand of electricity for cotton field irrigation in remote areas of southern Xinjiang, considering the full use of local good light resources, a light-storage combined power supply system for cotton field irrigation was designed. The system was mainly composed of the photovoltaic power generation unit, bidirectional DC-DC converter, converter and energy storage module, etc. While setting the system parameters, the system control strategy was designed, and the system simulation model was built by using the Simulink simulation platform. The simulation results showed that the system could not only respond quickly to photovoltaic power tracking and maintain the stable charging and discharging status of energy storage batteries, but also meet the requirements of cotton field irrigation load with ac output voltage.

Key words: cotton field irrigation, combined optical-storage power supply, control strategy, Simulink simulation
