摘要

摘要: 為了有效地保證智能電網(wǎng)中業(yè)務(wù)的隔離性和解決智能電網(wǎng)無線資源高效分配問題，該文借助網(wǎng)絡(luò)虛擬化技術(shù)，提出一種面向電力無線虛擬專網(wǎng)的資源優(yōu)化分配機(jī)制。首先，根據(jù)電力無線專網(wǎng)的特點(diǎn)，提出電力無線專網(wǎng)虛擬化系統(tǒng)模型，并通過建立網(wǎng)絡(luò)模型抽象物理無線資源，實(shí)現(xiàn)資源共享；然后，綜合網(wǎng)絡(luò)成本、利潤、業(yè)務(wù)隔離性約束、回程容量約束、QoS約束等因素，提出配用電接入網(wǎng)無線資源分配模型，且設(shè)計(jì)一種禁忌搜索的算法，在滿足業(yè)務(wù)隔離和業(yè)務(wù)QoS要求的情況下，解決了配用電無線專網(wǎng)最優(yōu)化虛擬資源分配。仿真實(shí)驗(yàn)表明，該文提出的基于禁忌搜索的電力無線虛擬專網(wǎng)資源優(yōu)化分配機(jī)制，在滿足業(yè)務(wù)QoS要求的情況下，降低了基站能耗，并提高了網(wǎng)絡(luò)運(yùn)行的經(jīng)濟(jì)效益。

Abstract: To guarantee the isolation of the smart grid business and optimize the allocation of wireless resources, an optimal resource allocation mechanism for electric power wireless virtual networks is proposed. First, a virtualization system model according to the characteristics of electric power wireless network is proposed, and abstract physical wireless resource is built to realize resource sharing. Then, a wireless resource allocation model with several factors is designed, which are network cost, profit, service isolation constraint, backhaul bandwidth constraint, and QoS constraints. Finally, a tabu search algorithm based on these models is designed to allocate virtual resource to realize business isolation and QoS requirements. The simulation results show that, the proposed network model and optimal resources allocation mechanism can support QoS requirements, reduce the energy consumption of base stations, as well as improve the economic benefits of the network.
