Power quality is one of the most prominent challenges hindering the spread and use of direct power control (DPC) in the field of control, especially for induction generator (IG) control. The lower power quality in the case of using the DPC approach is due to the use of hysteresis comparators. This work proposes a new controller to overcome the drawbacks of the DPC approach, such as low robustness and high total harmonic distortion (THD) value of current for IG present in multi-rotor wind turbine (MRWT) based power system. The proposed controller is fractional-order third-order sliding mode control (FOTOSMC), as this controller is used to determine reference values for a voltage. In addition to using the FOTOSMC controller, the pulse width modulation strategy is used to control the operation of the machine inverter. The proposed approach differs from the traditional DPC approach and existing controls. This proposed approach is characterized by high robustness and high performance in improving power quality. The DPC approach based on the FOTOSMC controller was implemented in MATLAB with a comparison to the traditional DPC approach and some related works in terms of response time, jitter, steady-state error, and overshoot. Simulations under different wind conditions are performed to evaluate the designed strategy's performance and robustness against conventional methods, revealing substantial improvements in dynamic response and stability. The results show the superior dynamic performance of the developed algorithm in terms of enhancing the quality of active power (37.99%, 55.04%, and 44.44%) and reactive power (49.17%, 27.27%, and 30.87%) in the two tests compared to the DPC. This control method effectively reduces the THD by 42.35%, 41.25%, and 31.36% compared to the DPC, resulting in a more efficient and reliable wind energy conversion system. This research confirms the effectiveness and efficiency of the proposed approach in renewable energy applications. It promotes the most efficient and sustainable energy solutions, making it a promising solution in other industrial applications.
电能质量是阻碍直接功率控制（DPC）在控制领域推广和应用的最突出挑战之一，特别是在感应发电机（IG）控制方面。采用DPC方法时电能质量较低是由于使用了滞环比较器。这项工作提出了一种新的控制器，以克服DPC方法的缺点，例如基于多旋翼风力发电机（MRWT）的电力系统中IG存在的鲁棒性低和电流总谐波失真（THD）值高的问题。所提出的控制器是分数阶三阶滑模控制（FOTOSMC），因为该控制器用于确定电压的参考值。除了使用FOTOSMC控制器外，还采用脉宽调制策略来控制电机逆变器的运行。所提出的方法不同于传统的DPC方法和现有控制方法。该方法的特点是具有高鲁棒性和在提高电能质量方面的高性能。基于FOTOSMC控制器的DPC方法在MATLAB中实现，并与传统DPC方法以及一些相关工作在响应时间、抖动、稳态误差和超调方面进行了比较。在不同风况下进行了仿真，以评估所设计策略相对于传统方法的性能和鲁棒性，结果表明在动态响应和稳定性方面有显著改善。结果表明，与DPC相比，所开发算法在两次测试中在提高有功功率质量（37.99%、55.04%和44.44%）和无功功率质量（49.17%、27.27%和30.87%）方面具有卓越的动态性能。与DPC相比，这种控制方法有效地将THD降低了42.35%、41.25%和31.36%，从而形成了一个更高效、可靠的风能转换系统。这项研究证实了所提出方法在可再生能源应用中的有效性和效率。它推动了最有效和可持续的能源解决方案，使其成为其他工业应用中有前景的解决方案。
