Abstract: A system and method are provided for a bandwidth manager for packetized data designed to arbitrate access between multiple, high bandwidth, ingress channels (sources) to one, lower bandwidth, egress channel (sink). The system calculates which source to grant access to the sink on a word-to-word basis and intentionally corrupts/cuts packets if a source ever loses priority while sending. Each source is associated with a ranking that is recalculated every data word. When a source buffer sends enough words to have its absolute rank value increase above that of another source buffer waiting to send, the system “cuts” the current packet by forcing the sending buffer to stop mid-packet and selects a new, lower ranked, source buffer to send. When there are multiple requesting source buffers with the same rank, the system employs a weighted priority randomized scheduler for buffer selection.

Abstract: The present invention relates to a method for identifying parameters of a 10 kV static load model based on similar daily load curves. In the present invention, an optimization model for identifying full-period parameters of the static load model is proposed based on a large number of daily load curves with response characteristic, a structure and constraints of the static load model, and two theoretical basic assumptions about loads. Full-period (including 96 moments) static voltage model parameters of 10 kV loads are given through optimization solution. A rule that active power and reactive power of the loads at each moment change with voltage is obtained. In addition, a change rule of load constituents is obtained. The method delivers good applicability, satisfies actual demands, and is suitable for large-scale static model analyses for 10 kV loads.
