Online Optimal Feedback Voltage Control of Wind Farms: Decentralized and Asynchronous Implementations
Yifei Guo, Houlei Gao, Dong Wang, Qiuwei Wu
Abstract
In this letter, we propose an optimal voltage feedback control algorithm for wind farms where the voltage set-point of wind-farm-side voltage source converter (WFVSC) and reactive powers of wind turbines (WTs) are coordinated. The proposed control establishes on the gradient descent and operates in an online fashion. Each WT updates its reactive power based on the local instantaneous terminal voltage and therefore, the proposed control can be implemented in a decentralized manner. Besides, we also address its asynchronous counterpart to enhance the practical applicability in real world.
