近年来，风能一直是最具可持续性的能源之一。风力涡轮机行业已经取得了巨大的进步，支持这一重要来源作为标准的可持续资产。在这项研究工作中，讨论了连接到工业设备的风力涡轮机系统的综合控制，其中已经开发了一种算法，该算法允许控制结构利用连接到电网侧的四桥臂逆变器来注入可用能量，以及作为有源电力滤波器来工作，从而减轻负载电流扰动并提高电能质量。一个四线制系统被认为是与三相和单相的线性和非线性负载。在风力涡轮机的连接期间，除了根据需要提供有功功率和无功功率之外，公用事业侧控制器被设计为补偿在存在无功、非线性或不平衡的单相和同相负载的情况下引起的干扰。当没有可用的风力发电时，控制器的目的是使用直流链路电容器与连接到电网的功率转换器来改善电能质量。所提出的方法相对于其他文献中的主要区别是，所提出的控制结构是基于保守的功率理论分解。这种选择为逆变器控制提供了去耦的功率和电流基准，提供了非常灵活、选择性和强大的功能。在MATLAB中进行了实时软件基准测试，以评估所提出的控制算法的全实时实现的性能。
Wind has been a standout amongst the most other sources of sustainable power over these years. There have been huge improvements in the wind turbine industry supporting this vital source as a standard sustainable asset. a comprehensive control of a wind turbine system connected to an industrial plant is discussed in this research work, where an algorithm has been developed allowing a control structure that utilizes a four-leg inverter connected to the grid side to inject the available energy, as well as to work as an active power filter mitigating load current disturbances and enhancing power quality. A fourwire system is considered with three-phase and single-phase linear and nonlinear loads. During the connection of the wind turbine, the utility-side controller is designed to compensate the disturbances caused in presence of reactive, nonlinear or unbalanced single and intra-phase loads, in addition to providing active and reactive power as required. When there is no wind power available, the controller is intended to improve the power quality using the dc-link capacitor with the power converter attached to the grid. The main difference of the proposed methodology with respect to others in the literature is that the proposed control structure is based on the conservative power theory decompositions. This choice provides decoupled power and current references for the inverter control, offering very flexible, selective, and powerful functionalities. Real-time software benchmarking has been conducted in MATLAB to evaluate the performance of the proposed control algorithm for full real-time implementation.
