风力发电研究缓慢的现象，使用一个详细的模型，可以很难执行与传统的离线模拟程序。由于计算能力和高速输入输出，实时模拟器能够在短时间内使用关键组件的详细模型对风廓线进行重复模拟，并允许通过硬件在环（HIL）测试原型控制器。本文讨论的方法，以克服实时模拟风力系统的挑战，其特点是其复杂性和高频开关。采用实时半实物仿真方法研究了一种耦合在风力涡轮机发电机中的混合液流电池-超级电容储能系统（ESS）的稳定性。原型控制器嵌入在一个实时仿真器中，而系统的其余部分在另一个独立的仿真器中实现。详细的风力发电系统模型的仿真结果表明，混合ESS具有更低的电池成本，更长的电池寿命，并提高了其参考ESS的整体效率。
Wind power generation studies of slow phenomena using a detailed model can be difficult to perform with a conventional offline simulation program. Due to the computational power and high-speed input and output, a real-time simulator is capable of conducting repetitive simulations of wind profiles in a short time with detailed models of critical components and allows testing of prototype controllers through hardware-in-the-loop (HIL). This paper discusses methods to overcome the challenges of real-time simulation of wind systems, characterized by their complexity and high-frequency switching. A hybrid flow-battery supercapacitor energy storage system (ESS), coupled in a wind turbine generator to smooth wind power, is studied by real-time HIL simulation. The prototype controller is embedded in one real-time simulator, while the rest of the system is implemented in another independent simulator. The simulation results of the detailed wind system model show that the hybrid ESS has a lower battery cost, higher battery longevity, and improved overall efficiency over its reference ESS.
