This paper proposes a novel seam-less transfer method for microgrid connected fuel cell inverters (FCIs) between voltage source and current source modes.In order to protect the fuel cell, the FCI output power should be restricted when the microgrid frequency is greatly disturbed.In this sense, the FCI is transfered from voltage source mode to constant current source mode.Meanwhile, the FCI is transfered from constant current source mode to voltage source mode until service can be restored.The proposed method can cooperatively work with well developed virtual synchronous generator (VSG) control algorithm so that these FCIs are able to share load among them as well as subsist under transient events of the system.Theoretical analysis and experimental results validate effectiveness of the proposed method.

传统水平轴风力机攻角调节采用航空器的机翼攻角调节理论,即最大升阻比理论.但是随着对风力机研究的不但深入,两者之间的差异不断显现出来,逐渐发现在最大升阻比状态下,风力机风能利用系数并不能达到最大.为了进一步提高风力机风能利用系数,本文应用叶素动量(BEM)理论对风力机传统攻角调节进行改进.发现适当减小攻角可以使风力机风能利用系数得到一定提高.针对三叶片NACA0012翼型水平轴风力机的算例进一步验证

随机无功备用优化是大规模新能源接入下维护电力系统安全稳定运行的有效手段,针对目前的随机无功备用优化不能控制目标函数风险的缺陷,本文首先建立考虑目标函数置信水平的随机无功备用优化模型,并采用基于样条重构的Nataf变换重构生成风速样本,然后采用蒙特卡洛法将原问题转化为多次的确定型优化运算,最后采用帝国竞争算法对问题进行求解.算例分析的结果表明,相比于传统基于期望值目标函数的随机无功备用优化,本文提出
