随着大规模新能源接入电网,新型电力系统“低惯量、弱支撑”特征凸显,电网频率调节资源日益稀缺,系统频率稳定问题愈发严峻。先进绝热压缩空气储能(advanced adiabatic compressed air energy storage,AA-CAES)具有容量大、寿命长等优势而受到广泛关注,但由于其储能和释能过程涉及气-热动态耦合过程,调频特性较为复杂,调频潜力还有待挖掘。因此,首先建立AA-CAES系统全工况动态仿真模型,进而基于期望频率动态曲线设计AA-CAES系统调频传递函数,优化目标传递函数关键参数,实现AA-CAES最小动态功率补偿下满足系统频率调节需求。最后通过仿真实验,验证了所提控制策略可优化AA-CAES调频容量的同时减小系统的稳态频率偏差与频率超调量,显著改善频率响应特性,为建设电网友好型AA-CAES电站提供技术支撑。

先进绝热压缩空气储能(advanced adiabatic compressed air energy storage system,AA-CAES)仿真建模及分析是其工程实践的基础。然而,目前模型一般基于理想工况建立,分析结果与实际工况相偏差较大,无法指导工程应用。为此,在传统热力学模型基础上,考虑了空气流动阻力损失和能量转换设备损耗等因素,建立了面向工程应用的AA-CAES模型并以200MW盐穴AA-CAES系统为例进行了分析。同时,对系统效率分析方法进行改进并对其进行了先进㶲分析。结果表明,空气管道㶲损失占总㶲损失比例接近7%,能量转换设备损耗导致电-电效率比轴功效率低5%,二者对系统性能影响较大,在进行工程设计时不可以忽略。系统各部件可避免㶲损失占比均较大,表明系统具有较大的性能提升潜力。各部件㶲损失为其内部㶲损失,与其他部件是否工作在最佳状态关系不大。

作者： Yimin SUN shengwei mei Qiang LU Department of Electrical Engineering Tsinghua University Beijing 100084 China

In this paper, we investigate the global controllability of a class of n-dimensional affine nonlinear systems with n- 1 controls and constant control matrix. A necessary and sufficient condition for its global controllability has been obtained by using the methods recently developed. Furthermore, we generalize the above result to a class of affine nonlinear systems with a block-triangular-like structure. Finally, we will give three examples to show the applications of our results.

控制理论与应用（英文版） 2008年第1期6卷 53-58页

作者： Xiangping NI shengwei mei The State Key Lab of Power Systems Department of Electrical Engineering Tsinghua University Beijing 100084 China

To analyze and control complex networks effectively, this paper puts forward a new kind of scheme, which takes control separately in each area and can achieve the network’s coordinated optimality. The proposed algorithm is made up of two parts: the first part decomposes the network into several independent areas based on community structure and decouples the information flow and control power among areas; the second part selects the center nodes from each area with the help of the control centrality index. As long as the status of center nodes is kept on a satisfactory level in each area, the whole system is under effective control. Finally, the algorithm is applied to power grids, and the simulations prove its effectiveness.
