  • Power management for DC microgrid enabled by solid-state transformer
    IEEE Transactions on Smart Grid, 2014
    Co-Authors: Xunwei Yu, Xiaohu Zhou, Xu She, Alex Q Huang
    Abstract:

    A novel distributed power management scheme is proposed in this paper for a DC microgrid system, which is enabled by Solid-State transformer (SST). The proposed system includes distributed renewable Energy resource (DRER) and distributed Energy Storage Device (DESD). The proposed distributed control algorithm, which only relies on the local information and guarantees full utilization of each module in the system based on their characteristics, is applied to both SST and DC microgrid. To this end, a simulation platform is developed in MATLAB/Simulink, in which Photovoltaic (PV), fuel cell and battery are selected as the typical DRERs and DESD, respectively. Lastly, several typical case studies are carried out and the simulation results verify the proposed distributed power management.

  • On integration of solid-state transformer with zonal DC microgrid
    IEEE Transactions on Smart Grid, 2012
    Co-Authors: Xu She, Srdjan Lukic, Alex Q Huang, Mesut. E. Baran
    Abstract:

    The contribution of this paper has been focused on investigating a new microgrid architecture that integrates the solid-state transformer with zonal dc microgrids. By utilizing the dc and ac links of the solid-state transformer, both ac and dc networks can access the distribution system, which renders the coordinate management of the power and guarantees high power supply reliability. In addition, the presented system together with the proposed power management strategy can minimize the effect of newly established zonal dc microgrid to the existing power grid, of which promises a better stability. To this end, this paper takes the photovoltaic and battery as the typical renewable Energy resource and Energy Storage Device, and develops a simulation platform for system study. Simulation results are shown to demonstrate the feasibility of the proposal.

  • all in one shape adaptive self charging power package for wearable electronics
    ACS Nano, 2016
    Co-Authors: Hengyu Guo, Min Hsin Yeh, Chenguo Hu, Yunlong Zi, Zhen Wen, Yingchih Lai, Changsheng Wu, Zhong Lin Wang
    Abstract:

    Recently, a self-charging power unit consisting of an Energy harvesting Device and an Energy Storage Device set the foundation for building a self-powered wearable system. However, the flexibility of the power unit working under extremely complex deformations (e.g., stretching, twisting, and bending) becomes a key issue. Here, we present a prototype of an all-in-one shape-adaptive self-charging power unit that can be used for scavenging random body motion Energy under complex mechanical deformations and then directly storing it in a supercapacitor unit to build up a self-powered system for wearable electronics. A kirigami paper based supercapacitor (KP-SC) was designed to work as the flexible Energy Storage Device (stretchability up to 215%). An ultrastretchable and shape-adaptive silicone rubber triboelectric nanogenerator (SR-TENG) was utilized as the flexible Energy harvesting Device. By combining them with a rectifier, a stretchable, twistable, and bendable, self-charging power package was achieved fo...

    Co-Authors: Joonho Bae, Youngjun Park, Minbaek Lee, Seungnam Cha, Young Jin Choi, Churl Seung Lee, Jong Min Kim, Zhong Lin Wang
    Abstract:

    Recently, there has been great interest in wearable and stretchable Energy generation and Storage Devices utilizing nanotechnology for applications such as self-powering nanosystem that harvests its operating Energy from the environment. [ 1 ] Solar, mechanical and thermal Energy can be scavenged from the environment using Devices that were fabricated using fl exible or stretchable substrates. For example, textile-fi bre-based nanogenerators have been demonstrated utilizing ZnO nanowires (NWs) grown on Kevlar fi bres to scavenge low-frequency mechanical Energy. [ 2 ] Twisted fi bre-like electrodes have been used for harvesting solar Energy using the dye-sensitized solar cells (DSSCs) approach. [ 3 ] Once the Energy is harvested from the environment, an Energy Storage Device is required in order to maintain the operation of the system, but it is usually a separated unit from the Energy converters. Flexible batteries. [ 4 ]
