With the global financial crisis, the new energy industry is brewing new economic growth points, as well as strategic commanding point of a new round of international competition. The development of large-scale non-grid-connected wind power application techniques has been breaking the bottleneck of traditional grid-connected technology. In terms of the wind power proportion in the entire power grid, this development has significantly reduced the failure rate of wind turbine, as well as avoiding the impact load on the power grid. Based on the analysis of non-grid-connected wind power investment fields, market prospects, government policy, technical and risk countermeasure, this article explains the investment value and competitive advantage of non-grid-connected wind power applications in the development of new energy industry.
