Abstract
Currently, research on wind power integration capacity based on peak load regulation constraint is mainly aimed at provincial power grids. Regional and provincial power grids are quite different, and wind power integration capacity of provincial grids is of little reference value for regional wind power planning. In this paper, According to the basic principles of wind power capacity assessment, the maximum output factor under certain probability is taken as the regional wind power output coefficient. Then, the assessment method of wind power capacity is proposed for receiving-end and sending-end power grids, considering the interregional tie-line power adjustment and unit maintenance. Finally, the wind power integration capacity of a regional power grid is assessed as an example to prove the validity of the proposed method.
