Research on Strategy of DC Micro-grid Control and Protection

    Abstract
  •   Introduction   The control and protection technology of DC microgrid plays an important role in ensuring the reliable and safe operation of DC microgrid. The paper aims to solve the key technologies in the design of DC micro-grid.
      Method  DC bus topology selection， control strategy， and protection configuration scheme were discussed in the paper.
      Result  The selection principle of DC bus topology structure， the control strategy process of DC micro-grid， protection zone and configuration are given in the paper. At the same time， the selection of DC transformer is analyzed and compared.
      Conclusion  The method has been validated in national demonstration projects， and it has performed well since it was put into operation.
