Led by the national dual-carbon strategy, the new energy industry develops rapidly, and hydraulic systems are widely used in wind power, photovoltaic, energy storage, and new energy machinery. New energy equipment requires high stability, load capacity, and environmental adaptability. Hydraulic systems feature high power density and stable operation. In wind turbines, hydraulic pitch and yaw systems ensure stable performance. Domestic enterprises develop reliable and intelligent products suitable for new energy scenarios. In the future, hydraulic technology will integrate deeply with new energy equipment, promoting efficient, low-carbon, and intelligent development for China’s green energy transition.
