A resource allocation method of smart grid based on heterogeneous network

基于长期演进标准的蜂窝技术是智能电网通信网络常用的技术。然而,当许多智能电网设备同时尝试接入时,会有无线接入网络阻塞现象的出现。异构蜂窝网络是解决这一问题的重要技术,在智能电网中,为了保证电网的稳定性,相量测量单元的实时数据有着严格的时延要求。提出一种联合资源分配和功率控制方案来改善异构蜂窝网络的端到端时延,同时考虑相量测量单元传输的方法。该方法将优化问题转换为混合整数问题,并采用博弈论方法和最优反应动态算法来进行计算。实验表明,与现有方法相比,该方法能显著减小端到端时延。

Cellular technology based on long-term evolution standards is a common technology for smart grid communication networks.However,when many smart grid devices try to connect at the same time,wireless access network congestion would happen.The heterogeneous cellular network is an important technology to solve this problem.In the smart grid,in order to ensure the stability of the grid,the real-time data of the phasor measurement unit has strict delay requirements.This paper proposes a joint resource allocation and power control scheme to improve the end-to-end delay of heterogeneous cellular networks,while considering the method of phasor measurement unit transmission.This method converts the optimization problem into a mixed integer problem,and uses the game theory method and the optimal response dynamic algorithm to calculate.Experiments show that compared with existing methods,this method can significantly reduce end-to-end delay.
