| 摘要: |
| 微电网与配电网互动运行的成本决定了其参与配电网运行的深度和广度。提出了一种基于灵敏度分析的微电网互动运行成本计算方法，首先设计了微电网与配电网互动运行的架构，然后考虑微电网的购电成本、售电收益、分布式电源发电成本，建立了微电网的优化调度模型，并在此基础上建立了考虑配电网互动容量需求的微电网优化调度模型，通过灵敏度分析得到了微电网互动容量与互动成本之间的关系，最后通过典型的微电网算例验证了所提算法的有效性。 |

| Abstract: |
| The cost of microgrid for its interactive operation with distribution network decides its participating depth and width，for which，a calculation method based on the sensitivity analysis is proposed. An interactive operation framework of microgrid with distribution network is designed and an optimal microgrid dispatch model considering the electricity purchase cost，electricity sale revenue and distributed generation cost is established，based on which，an optimal microgrid dispatch model considering the capacity needed by the interactive operation is proposed. The sensitivity analysis is applied to obtain the relationship between the capacity and cost of interactive operation. The study of a typical case verifies the effectiveness of the proposed method. |
