配电网中可再生能源转换系统的连接必须符合保证电能质量和电网辅助要求的规范。传统配电系统中使用多年的控制策略并不总能满足新的运行要求。在此背景下，本文从无源控制的概念出发，研究了风力发电机组的控制问题。特别提出了一种基于无源理论的新方法——功率整形的控制策略。这种方法允许考虑普遍耗散。所提出的策略在极端运行条件下进行了评估，显示了通过电网故障的能力。这样，仿真结果鼓励了功率整形概念在更复杂的分布式发电系统中的应用。
The connection of renewable energy conversion systems in distribution networks must comply with codes for assuring power quality as well as the grid assistance demands. The new operating requirements cannot always be achieved from the control strategies that have been employed for years in conventional distribution systems. In this context, this paper addresses the problem of controlling a wind turbine from passivity control concepts. In particular a control strategy based on a new approach to the passivity theory, known as Power Shaping, is proposed. This approach allows to consider pervasive dissipation. The proposed strategy is evaluated in the context of extreme operating conditions showing capability to ride through grid failures. In this way, the simulation results encourage the application of concepts of Power Shaping in more complex systems of distributed generation.
