摘要：随着电动汽车、光伏发电等越来越多的新型电网交互型设备接入楼宇,以往的楼宇变电站难以处理复杂的能量流动,导致能量传递效率降低、接口复杂化和电能质量变差的现象。为此,提出一种无线电能路由器与电能质量控制方法。首先,为设计高效的能量流动控制方法,提出无线电能路由器构成的等效模型;其次,为了在所有负载、电能质量情况中保持高效的能量流动,对不同负载、电能质量情况进行分类并给出相应的控制参考量;随后,基于所有分类的控制参考量,设计对不同负载、电能质量情况下的功率控制方法;最后,为验证所提结构和控制方法的可行性,设计相对应情况的仿真案例。所提无线电能路由器可以为楼宇提供一种统一接入电网交互型设备的解决方案,具有重要的工程意义。

摘要：Topological phase is an important development and unexplored degree of freedom of traditional band theory[1].Generally,it manifests in physics through the boundary states revealed by the bulkedge *** bulk topology implies various low-dimensional states at the boundary,giving extraordinary approaches to manipulate *** structure that encodes the band topology is the system associated with space–time evolution,such as Floquet topological insulator[2,3].Its quasistatic limit involves time-dependent dynamic adiabatic evolution[4,5].However,dynamic evolution is challenging as it requires fast modulation to overcome the dissipation of state before it is pumped from one edge to another[6].An alternative approach is to use an additional degree of freedom to replace the role of time,and an illuminating system is the weakly coupled waveguides,whose governing equation can be directly mapped to Schrodinger equation with time modulation replaced by wave propagation along the ***,such strategy has been largely explored to realize the pumping of topological boundary states in optics[7,8]and elastic wave[9,10].However,the strategy for acoustics is subtly different as the coupling of the acoustic waveguides is not weak for the fundamental waveguide *** exploring the possibility to realize two-dimensional(2D)topological acoustic pumping in a continuous regime remains an open question.
