论文摘要
分销系统将需要新的成本效益的解决方案，以提供网络容量并提高灵活性以适应低碳技术。为了满足这一需求，我们提出了混合多末端软开放点（混合MT-SOP），以有效地提供分配系统互连能力。混合MT-SOP的每条腿都有一个与AC开关（进纸器选择器开关）串联连接的AC/DC转换器，以允许转换器连接到节点处的任何馈线。在三端情况下，不对称转换器的尺寸显示可将可行的功率传输提高多达50％，而圆锥混合构成程序则配制了以最佳选择设备配置和功率传输。一项案例研究表明，与同等大小的MT-SOP相比，混合MT-SOP的增加了转换器的利用率超过三分之一，系统损失减少了13％。
Distribution systems will require new cost-effective solutions to provide network capacity and increased flexibility to accommodate Low Carbon Technologies. To address this need, we propose the Hybrid Multi-Terminal Soft Open Point (Hybrid MT-SOP) to efficiently provide distribution system interconnection capacity. Each leg of the Hybrid MT-SOP has an AC/DC converter connected in series with a bank of AC switches (Feeder Selector Switches) to allow the converter to connect to any of the feeders at a node. Asymmetric converter sizing is shown to increase feasible power transfers by up to 50% in the three-terminal case, whilst a conic mixed-integer program is formulated to optimally select the device configuration and power transfers. A case study shows the Hybrid MT-SOP increasing utilization of the converters by more than one third, with a 13% increase in system loss reduction as compared to an equally-sized MT-SOP.
