Abstract: Aiming at the problem of Mongolian UHV DC into Hubei power grid in 2018 and 2020, the space of peak shaving that can be used by Hubei power grid and can be transmited outside was comprehensively considered, the acceptance capacity of wind power of Hubei Power Grid with Mongolia UHV DC accessing was studied. A wind power acceptance capacity calculation method under the restraint condition based the sysyems peak regulation capability was presented, and the prospect plan of Hubei Power Grid about consumptive outside wind power and the space of wind power development in Hubei province were discussed. The maximum wind power capacities of Hubei Power Grid in wet season, dry season in 2018, dry season in 2020 were calculated. The results indicate the acceptance capacity of wind power is limited during the prospect plan of Hubei Power Network because of the system s peak regulation capacity, the conclusion can provide a reference for Hubei Power grid to get wind power from Western Inner Mongolia and to develop wind power in Hubei province.
