摘要

随着电网负荷需求的日常变化,海上和陆上风电场的持续整合为电网提供绿色能源,由于发电侧的额外变化,最近导致了严重的频率稳定性问题。因此,在其他可再生能源装置中,风力涡轮机(WTs)需要调节其输出功率,以减轻发电功率的波动并支持频率稳定。本文采用自适应方法实现模型预测控制(MPC),使WT在风扰动下处于卸载模式。此外,获得WTs的全面运行,满足网格规范要求;为了模拟传统发电机固有的同步和负荷共享特性,在WT转子侧变换器中提出了一种新的成网控制器。该控制方法考虑了转子转速和转子侧变换器的局限性。

Optimal active power control of wind turbines in grid-forming mode
Together with the daily variation of load demand in power grids, the continuous integration of offshore and onshore wind farms to feed the grid with green energy has recently led to a severe frequency stability issue due to the extra variation in the generation side. Hence, wind turbines (WTs), among other renewable energy units are required to regulate their output power to mitigate the fluctuation in generated power and support frequency stability. In this paper, model predictive control (MPC) is implemented in an adaptive way to operate WT in de-loading mode under wind disturbances. In addition, to get comprehensive operation of WTs and meet grid code requirements; we present a new grid-forming controller in the WT rotor side converter to emulate the inherent synchronizing and load sharing property of conventional generators. The limitations of rotor speed and rotor side converter are considered in the proposed control approach.
