The high penetration of distributed energy resources (DERs) causes huge pressure on the operation and management. In this paper, the distribution network is divided into regions based on the sectionalizing switch position. Each region receives the optimization goal from global optimal power flow (OPF) algorithm. Regional optimization algorithm is based on the indicator of feeder control error (FCE)[1]...
With the explosion increasing data in Internet, high performance scalable router has become a hot spot research area both in academe and industry recently. The underlying topology is a very important fold for scalable router. In this paper, we propose a new underlying topology of the scalable router, and name it Compressed 3D-Torus (C3D-Torus). It's more like the 3D-Torus, which is a famous architecture...
Load-balanced architectures appear to be a promising way to scale Internet to extra high capacity. However, architectures based on mesh topology have a node-degree of N, which prevents these architectures from large node numbers. This consideration motivates us to study the properties of node degree and its impact on the corresponding load-balanced architectures. In this paper we first show the asymptotically...
A new AC-DC-AC matrix converter topology based on Sepic is proposed. The basic configuration of the new topology and its fundamental principle are firstly introduced, the analytic expression on the function of voltage transfer ratio and duty cycle is analyzed, and the rationale of double-loop control strategy is clarified. Finally the validity and feasibility of the new topology are tested by means...
