AI Technical Summary

Technical Problem

Traditional agricultural irrigation operations put enormous pressure on rural power grids. Especially during the irrigation cycle, the disorderly nature of centralized electricity and water use increases farmers' costs and power grid safety issues. Meanwhile, the widespread adoption of photovoltaic power generation in agriculture has failed to effectively coordinate the conflict between electricity and water use.

Method used

A two-layer interactive game framework between the power distribution network and the agricultural irrigation park is constructed. The model is solved by particle swarm optimization and CPLEX toolbox to optimize time-of-use pricing and reconfiguration schemes, thereby achieving optimal decision-making in the agricultural irrigation park. Combined with photovoltaic access, the contradiction between electricity and water use is balanced, and the agricultural irrigation method is optimized.

Benefits of technology

This has enabled the transformation of agricultural irrigation water use from extensive and inefficient to economical and efficient, supported the safe and reliable operation of rural medium and low voltage power distribution networks, reduced the pressure on the power grid, and enhanced the win-win benefits for both parties.
