| 摘要: |
| 配电网负荷增加或分布式电源（DG）的接入将导致供电设备扩容的提前或延迟，从而引起容量成本的变动。根据辐射形配电网潮流特点，推导得到节点注入功率对支路电流影响的灵敏度系数，并结合节点-支路潮流关联矩阵，建立相应的灵敏度系数矩阵，用于计算配电网节点边际容量成本（LMCC）。基于LMCC，在用户自备的产权下，分析评估不同电价体制下的DG容量效益；在电网所有的产权下，建立多类型DG规划模型，并采用粒子群优化算法求解优化模型。算例对比验证了模型和方法的可行性。 |

| Abstract: |
| The load increase or DG（Distributed Generator） integration of distribution network may advance or delay the expansion of power-supply equipment and then cause the change of capacity cost. The sensitivity of branch current to the nodal injection power is deduced according to the power flow of radial distribution network，which is combined with the node-branch power-flow correlation matrix to build the corresponding sensitivity matrix for calculating the LMCC（Locational Marginal Capacity Cost） of distribution network. For the DG owner，LMCC can be used to evaluate the DG capacity benefit under different electricity price systems；for the grid with DGs，it can be used to build a multi-type DG planning model，which is then solved by the particle swarm optimization algorithm. Case study verifies the feasibility of the proposed model and method. |
