In according with the volatility of renewable energy such as wind power in China，large-scale of which cannot be consumption by grid，the non-grid-connected wind power theory is proposed in this paper.The high energy consumption load is transformed into smart load which can adapt to the fluctuation of energy，greatly improve the utilization of renewable energy.The paper discuss the essence and connotation of non-grid-connected wind power?theory，and the?application of non-grid-connected wind power theory，for China’s?energy saving and emission reduction，proposed?a new path to improve the utilization rate of network efficiency and renewable energy.
