  • A Novel Solid-State Circuit Breaker for On-Board DC Microgrid System
    IEEE Transactions on Industrial Electronics, 2019
    Co-Authors: Yufeng Wang, Xiaobin Zhang
    Abstract:

    The development of the dc Microgrid System on-board has promoted the development of the dc circuit breaker, but short circuit fault may cause serious damage to the System. Many problems exist in the traditional dc circuit breaker such as long periods of fault interruption, complex circuit structure, existing arc, low reliability, and low anti-interference. Aiming to solve these problems, a novel solid-state dc circuit breaker is proposed in this paper. First, this paper analyzes the working principle and process of the circuit in detail according to the results of the simulation based on Saber. Second, this paper gives the criteria on how to choose the parameters of the components correctly in the circuit. The concept of the maximum fault resistance according to the minimum fault current is also introduced. Moreover, this paper analyzes the influence of the minimum fault ramp rate on the circuit performance. Finally, experimental results verify that the performance of this novel solid-state circuit breaker agree with the theoretical analysis.

  • A Novel Solid-State Circuit Breaker for DC Microgrid System
    2018 IEEE International Conference on Electrical Systems for Aircraft Railway Ship Propulsion and Road Vehicles & International Transportation Electri, 2018
    Co-Authors: Yufeng Wang, Xuanlyu Wu, Renyou Xie, Weilin Li, Zhiyong Zhang, Heng Wang
    Abstract:

    The development of the DC Microgrid System has promoted the development of the DC circuit breaker. However, the traditional DC circuit breaker exists many problems such as long period of fault interruption, complex circuit structure, existing arc, low reliability and low anti-interference. Aiming to solve these problems, an improved solid-state DC circuit breaker was proposed in this paper. This improved solid-state circuit breaker uses a transformer instead of LC legs which exist in the traditional Z-source circuit breakers to realize the function of turning off the thyristor. The working principle and designing process are discussed in this paper according to the results of simulation based on Saber. And the operation performance of the improved solid-state circuit breaker is validated by the calculation and simulation results.

  • techno economic potential of a renewable energy based Microgrid System for a sustainable large scale residential community in beijing china
    Renewable & Sustainable Energy Reviews, 2018
    Co-Authors: Shiyue Zhang, Yizhong Chen, Lixia Ren
    Abstract:

    Abstract In this study, the techno-economic potential and optimal configuration are investigated under various renewable energy (RE)-based, stand-alone and grid-connected Microgrid scenarios. HOMER software is employed to assess the physical, operating, and economic performance of the System’s components, and to obtain the most cost-effective configuration pattern. The outputs obtained from the case study for a residential community in Beijing can help the decision maker identify the optimal adoption of renewable energy sources, electricity generation, and economic benefits. Results show that there is a very high potential for applying a predominantly RE-based Microgrid in a residential community in Beijing, which could supply at least 90% of the onsite electricity demand with 47–100% RE sources. In the grid-connected model, the total net present cost (TNPC) of the Microgrid System would be, at most, 57% of the obtained electricity less than that completely from the external grids. Results also indicate that it would be more cost-effective when wind power becomes the main energy source and combined with moderately capacity of solar photovoltaic (PV) in the RE hybrid Microgrid System. Additionally, a System with moderate size of batteries tends to be more ecologically friendly and cost-effective both in the stand-alone and grid-connected models than a System without batteries.
