Recent years, the wind power accommodation capacity of power grid is reduced resulting from the changes in the factors such as load conditions, power source structure and grid structure. It is significant to research the subject of wind power accommodation capacity for the sustainable development of wind power technology and the stable operation of power system. Therefore, this paper focuses on assessment measures for wind power accommodation capacity. Firstly, the time-space distribution characteristics of the measured data of wind farm output power are analyzed. Secondly, it provides the time series production algorithm for evaluating wind power accommodation capacity based on the characteristics of wind power and prediction algorithm of minimum/maximum load. Finally, taking one grid for an example, the wind power accommodation capabilities of power grid are evaluated in different quarters and operating conditions. Compared to power grid operation data, calculations indicate that the time series production algorithm can evaluate the wind power accommodation capacity and afford reference data to improve the grid’s accommodation capacity for wind power.
