This paper brings forward a new concept of “smart load” in accordance with China’s national conditions. It is the internet of things that combines the smart load with smart grid to constitute the “non-grid-connected multi-energy complementary smart grid system”. The core of the system is to transform a large number of energy-intensive industries in China into the “smart loads” that can be adapted to wind power and other renewable energy and huge fluctuations in grid output power through necessary technological innovation，thus providing Chinese government with a new path that can significantly improve the utilization efficiency of power grid and power generation equipment as well as take full advantage of high-efficient and low-cost renewable energy such as wind power pursuant to China’s national conditions.
