Mum was angry with me just now. Because I accompanied with my daughter doing her home work. Mum accused me that we were noisy and waked Erbao up. I don't dare to answer anything. How difficult it is to make Erbao sleep. Mum's effort is waste. That father did do something. Sitting on the pad with Erbao for 10 minutes. That's all one father could do. Don't demand much is the possibility of harmony.

看看月亮背背诗[二哈]
直道相思了无益，未妨惆怅是清狂
山回路转不见君，雪上空留马行处
满堂花醉三千客，一剑霜寒十四州
惟将终夜长开眼，报答平生未展眉
​从此无心爱良夜，任他明月下西楼
空床卧听南窗雨，谁复挑灯夜补衣
I waked, she fled, and day brought back my night.

荷兰代尔夫特理工大学（TU Delft）的研究人员开发一种控制器，通过“有功功率控制（Active power control，APC）”更好地管理风电场能量，有助于提高风电场的效率。

为了跟踪风力机的功率，该方法采用闭环算法，将单个风机视为纯时滞系统。算法具有前馈和反馈回路。前者确保在风机未饱和时跟踪功率，后者在有1个风机（但不是全部）饱和时跟踪功率。

研究人员在高保真风力发电厂模拟器SOWFA上进行了一系列测试，来评估了该控制器。结果表明，与贪婪操作（greedy operation）相比，关闭控制回路可提高发电量。该方法总有功功率跟踪响应显著改善，发电量比基准方法提高了15%。

然而，该团队还观察到该闭环解决方案的有功功率出现了一系列不希望出现的小峰值和振荡。在接下来的研究中，他们将尝试设计一种策略来消除或适应这些振荡，以提高方法的性能和可靠性。

研究发表在arXiv.
