摘要

为协调风电场之间的无功输出,提出一种基于HMPC的电压控制方法,旨在提高大型风电场的高电压穿越和故障后电压恢复能力,并减少风电场控制器的计算任务。在风电场电压分层控制框架的基础上,首先从风电机组的单体控制模型出发建立风电场的整体控制模型,并采用HMPC方法滚动优化风电场输出无功功率;进一步,为提高大规模风电场电压优化问题的计算效率,采用基于交替方向乘子法的分布式求解方法。通过Matlab/Simulink搭建风电场仿真算例验证,结果表明所提HMPC方法相比传统控制方法在最小化风电机组端电压偏差和减少计算量方面具有更高的效率。

Abstract

In order to coordinate the reactive power output between wind farms, a voltage control strategy based on HMPC was proposed, which aims to improve the high voltage ride through and post fault voltage recovery capabilities of large wind farms, and reduce the computational tasks of wind farm controllers. Based on the hierarchical control framework of wind farm voltage, this paper first established the overall control model of the wind farm from the individual control model of the wind turbine, and used the HMPC method to rolling optimize the reactive power output of the wind farm; Furthermore, in order to improve the computational efficiency of voltage optimization problems in large-scale wind farms, a distributed solution method based on the alternating direction multiplier method was adopted. A wind farm simulation example was built using Matlab/Simulink for verification, and the results show that the proposed HMPC method has higher efficiency compared to traditional control methods in minimizing voltage deviation at the end of the wind turbine group and reducing computational complexity.
