论文摘要
分布式能源（DER）在分销网络中的渗透不断增加，已将传统的被动负载总线转变为可以为传输系统提供网格服务的活动总线。为了利用分销网络中的DERS，这封信通过利用大型发电机和DER来制定了传输和分布（T＆D）系统合作问题，该系统可以在传输级别实现经济调度，并在分配水平上进行最佳电压调节。提出了一种原始的双重梯度算法来共同解决T＆D系统的优化问题，并将基于分布式的基于市场的梯度算法等效用于实际实施。通过与7个不同分布网络相连的IEEE 39-BUS系统的数值示例来证实结果。
The increasing penetration of distributed energy resources (DERs) in the distribution networks has turned the conventionally passive load buses into active buses that can provide grid services for the transmission system. To take advantage of the DERs in the distribution networks, this letter formulates a transmission-and-distribution (T&D) systems co-optimization problem that achieves economic dispatch at the transmission level and optimal voltage regulation at the distribution level by leveraging large generators and DERs. A primal-dual gradient algorithm is proposed to solve this optimization problem jointly for T&D systems, and a distributed market-based equivalent of the gradient algorithm is used for practical implementation. The results are corroborated by numerical examples with the IEEE 39-Bus system connected with 7 different distribution networks.
