1、1. Project introduction：
This project aims to use wind power, solar power, DC micro power grid etc. new energy technologies to supply power for those oil pumping units for oil wells on the edge. When pumping unit works, the wind and solar power is priority used,the grid power is as backup. The system is innovative designed without energy storage system with low cost,which also makes contribution to the energy conservation and emission reduction.
