智能电网(Smart Grid,SG)中的需求响应管理(Demand Response Management,DRM)是SG的控制单元,用来平衡实时负荷及转移高峰时段负荷.通信对于DRM的准确性和最优性至关重要,在智能电网的邻域网中广泛采用无线网络作为通信网,但是用于无线通信的频谱资源目前未被充分利用.随着模拟广播电视向数字电视的过渡,在电视频谱中产生更多的电视空白(TV White Space,TVWS)频谱.基于此,通过及建立 Underlay 模式下的 TVWS 频谱共享分层网络模型,以提高频谱利用率,并提出基于非合作博弈功率控制算法.数值结果表明,提出的方法可以提高频谱的利用率,有益于发挥DRM的性能.
TV Spectrum Resource Allocation Based on Game Theory in Cognitive Smart Grid
Demand Response Management(DRM)in Smart Grid(SG)is the control unit of SG,which is used to balance real-time load and transfer peak load.Communication is crucial to the accuracy and optimality of DRM.Wireless network is widely used as a communication network in the neighborhood network of smart grid,but the spectrum resources used for wireless communication are not fully utilized at present.With the transition from analog broadcast television to digital television,more TV White Space(TVWS)spectrum is created in the television spectrum.Based on this,the TVWS spectrum sharing hierarchical network model under Underlay mode is established to improve the spectrum utilization rate,and a power control algorithm based on non-cooperative game is proposed.Numerical results show that the proposed method can improve the utilization rate of the spectrum and is beneficial to the performance of DRM.
