| 能源危机、环境问题以及直流负荷比例增大推动了直流配电网的发展，电力电子器件的灵活可控性使得直流配 电网的供电特性有别于传统交流配网，直流配电网络运行优化问题的研究当结合其特殊性。本文全面总结了直流配电 网中分布式电源、储能系统以及交直流AC/DC换流站以及负荷等端口的输出模型，然后以这些输出特性为基础对直流配电网进行网络分析，进而在直流配电网络分析的基础上建立以网络损耗最小为目标的优化模型，优化模型以联 络线功率限值、节点电压限值、各端口输出特性限值为约束条件。案例分析表明所提出的直流配电网络分析方法和优 化模型均是可行的，且可以从实时运行层面达到新能源高效被利用。 |

| Energy crisis, environmental issues and load demand promote the development of the DC distribution network .Flexible controllability of power electronic devices makes DC power distribution grid different from the traditional distribution network in many ways. Research about controllable DC network is supposed to combine with its unique characteristics. In this paper, a comprehensive summary of the output models of di?erent ports including the distributed resources, energy storage systems, AC/ DC converter station and load ports is provided, and then, based on these output characteristics make network analysis towards the DC distribution network .and then on that foundation, establish a optimization model whose objective is to maximize new energy consumptive capacity and minimize the transmission line loss, and whose control variables are the parameters of the port control strategies. Case study shows that the proposed DC distribution network analysis method and optimization model are feasible, and can be reach the highest of new energy utilization in the real-time operational level. |
