基于VSC-HVDC的风电分散并网下垂控制方法
摘要：
本发明公开了一种基于VSC‑HVDC的分散风电并网下垂控制方法，包括：步骤1、建立单风电场并网的VSC‑HVDC系统结构模型；步骤2，构建用于VSC‑HVDC系统结构模型配电网侧逆变器的定直流电压控制器；步骤3，构建用于VSC‑HVDC系统结构模型风电场侧整流器的交流电压下垂控制器；步骤4，根据配电网分布构建送端采用交流分散模式的多风电场并网的VSC‑HVDC系统结构模型，采用定直流电压控制器控制配电网侧逆变器，采用交流电压下垂控制器控制风电场侧整流器。本发明可给在受端采用交流汇合模式的分散风电场联合协调运行提供有效的解决途径，适用于远距离风电场并网控制。
摘要（英）：

The invention discloses a wind power dispersion and integration droop control method based on the VSC-HVDC. The method includes the steps that first, a VSC-HVDC system structure model for single wind power plant integration is established; second, a constant DC voltage controller for a power distribution network side inverter of the VSC-HVDC system structure model is established; third, an AC voltage droop controller for a wind power plant side rectifier of the VSC-HVDC system structure model is established; fourth, the VSC-HVDC system structure model for multiple-wind-power-plant integration in an AC dispersion mode at the sending end is established according to power distribution network distribution, the power distribution network side inverter is controlled by the constant DC voltage controller, and the wind power plant side rectifier is controlled by the AC voltage droop controller. According to the wind power dispersion and integration droop control method based on the VSC-HVDC, an effective solution can be provided for dispersion wind power plant joint coordination operation in an AC converging mode at the receiving end, and the method is suitable for remote wind power plant integration control.
