Abstract

The invention discloses a wind storage primary frequency modulation reserve capacity determination method based on a quartile proportion wind abandoning method. The method comprises the following steps: obtaining the maximum wind power generated power historical data in each time interval during one day in a wind power plant; arranging the data sequentially from small to large, and using the quartile method to divide the data into four parts; giving out the wind abandoning proportion coefficients of the four parts; calculating total reserve capacity provided by a wind storage system; considering the state-of-charge (SOC) of current stored energy, and calculating adjusting coefficient; after considering the stored energy, calculating the actual reserve capacity of the wind power plant according to the adjusting coefficients; and calculating the reserve capacity provided by the stored energy. According to the method, wind power and stored energy can be cooperative with each other to provide reserve capacity.

Description

technical field [0001] The invention relates to the field of wind power primary frequency regulation reserve capacity, in particular to a wind storage primary frequency regulation reserve capacity determination method based on the quartile ratio abandoned wind method provided by the wind power storage joint. Background technique [0002] Wind power is currently the most economical and mature renewable energy power generation technology, and its penetration rate in the power grid continues to increase. However, due to the strong volatility and uncertainty of wind power, there are many problems in actual consumption. Especially in the primary frequency regulation of the power system, the use ratio of traditional thermal power units will decrease, which will lead to insufficient primary frequency regulation capability of the system. Therefore, considering wind power's participation in power system primary frequency regulation has also become a hot research direction at present...
