Wind Energy (WE) penetration levels in rural grids are limited due to the Power Quality (PQ) issues owing to the inconsistency in the wind speed and low short circuit ratios. This is further aggravated due to the day-by-day increase in non-linear loads. This paper proposes a methodology to enhance WE penetration levels by mitigating PQ issues using distribution static compensator (DSTATCOM) controlled by the Adaptive Linear Element-Least Mean Square (ADALINE-LMS) algorithm. The proposed adaptive control algorithm estimates the active and reactive weight components of load currents by considering the changes in wind generation, DC-link voltage and grid voltage. These weights are used to generate reference current signals to switch the DSTATCOM to mitigate PQ disturbances. The proposed method has been implemented for the enhancement of WE penetration in the rural grid under the non-linear load. The results obtained by simulation in MATLAB studies have been validated using the experimental studies. These studies established the effectiveness of the proposed method for enhancing WE penetration level in rural grid up to 25%.

使用 ADALINE-LMS 控制分布静态补偿器提高农村电网的风能渗透水平


由于风速不一致和短路率低导致电能质量（PQ）问题，风能（WE）在农村电网中的渗透水平受到限制。由于非线性负载的日益增加，这种情况进一​​步加剧。本文提出了一种通过使用由自适应线性元最小均方 (ADALINE-LMS) 算法控制的分布式静态补偿器 (DSTATCOM) 缓解 PQ 问题来提高 WE 渗透水平的方法。所提出的自适应控制算法通过考虑风力发电、直流母线电压和电网电压的变化来估计负载电流的有功和无功权重分量。这些权重用于生成参考电流信号来切换 DSTATCOM 以减轻 PQ 干扰。所提出的方法已被实施用于增强非线性负载下农村电网中的WE渗透率。 MATLAB 研究中的模拟获得的结果已通过实验研究得到验证。这些研究证实了所提出的方法对于将农村电网中 WE 渗透率提高至 25% 的有效性。
