【 摘 要 】

The microgrid accessing to active distribution network can improve the reliability of the system, meanwhile supply partial load in place of high voltage distribution network. An assessment method of substation capacity credit of microgrid is proposed to evaluate the capacity value of grid-connected microgrid based on the principle of equal reliability. The secant method and the sequential Monte Carlo method for state transition are used to solve the model. To verify the effectiveness of the method proposed in this paper, the credible capacities of different microgrid types in various typical connection modes of a high voltage distribution network are quantitatively analyzed in the case study, which can provide a reference for the capacity planning of an active distribution network substation and grid structure selection.
