Non-grid-connected wind power strategic significance and path on the super large scale wind power utilization

Abstract

Wind power integration into the power grid is the only application mode of worldwide large-scale wind farms. The high instability of wind could cause a drastic fluctuation of wind power, which has restrained the contribution ratio of wind power to the power grid within 8–10% if there is no gas-fired power or hydro-power for peak shaving. It has become a tough worldwide problem. In the next 4–6 years with global large-scale wind power development, it is inevitable that the difficulties to integrate into the power grid will appear, which seriously restricts the development of global wind power industry. The proposed new application mode of “non-grid-connected” wind power fully takes into account the wind power characteristics, and breaks the single on-grid application mode of large-scale wind power. By the necessary technical innovation and integration, the non-grid-connected mode directly couples wind power with high-energy consumption industries (such as electrolytic aluminum, chlor-alkali, hydrogen production by water electrolysis, seawater desalination and coal chemicals, etc.), so as to build several green heavy chemical industry parks. It will explore a diversified development method of large-scale wind power to solve the application problem of super-large-scale wind power.
