Abstract

The invention relates to a wind power plant AGC and primary frequency modulation coordinated control method and system considering energy storage. The method comprises the following steps: S1, carrying out active power output instruction coordination on a wind power plant considering energy storage; s2, primary frequency modulation control; and S3, AGC control is carried out on the wind power plant considering energy storage. According to the wind power plant AGC and primary frequency modulation coordinated control method and system considering energy storage, it is guaranteed that the wind power plant considering energy storage can coordinate primary frequency modulation and wind power plant AGC, and safe and coordinated operation of a power system and the wind power plant is guaranteed.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind farm AGC and primary frequency modulation coordinated control control method and system considering energy storage. Background technique [0002] In recent years, wind power has been connected to the power system on a large scale, and the frequency regulation capability of traditional units has been further weakened. Therefore, wind farms are required to participate in power system frequency regulation. At present, wind farms mostly adopt automatic generation control (AGC) mode. When wind farms participate in primary frequency regulation of the power system, they often face different performance requirements from AGC. Therefore, primary frequency regulation needs to be coordinated with automatic generation control. [0003] In the prior art, Chinese Invention Patent Application Publication No. CN109066790A provides a wind farm primary frequency modulation an...
