Abstract

The invention relates to a wind farm energy storage optimization configuration method and system considering a dynamic current carrying characteristic. The method comprises the following steps of firstly, generating one or more typical wind farm area environment scenes according to historical meteorological data of a wind farm area, and generating output, in the typical scenes, of a wind generating set cluster in a wind farm and current carrying capacity demands of a design line in the scenes under the full-load condition of the wind farm; secondly, performing calculation to generate the dynamic current carrying capacity of the whole line corridor in the typical scenes; and finally, considering the dynamic current carrying characteristic in constraint conditions, establishing a wind farm energy storage system optimization configuration model, and solving the model to obtain optimal configuration of a wind farm energy storage system. According to the method and the system, the dynamic transmission capacity of the line is taken into consideration, so that the transmission capacity of the overhead transmission line of the wind farm is further exploited, the power transmission capacityof the overhead power transmission line of an electric power system is fully utilized, the asset utilization rate of a power grid can be improved, and the clean energy utilization level of the electric power system can be improved.

Description
