Analysis of Demand Response Error Cost and Energy Efficiency of Distributed Wireless Communication System in Smart Grid

针对无线通信的能量效率和需求响应误差成本严重影响系统的运行成本,提出一种基于超密集组网结构的无线通信网络,在提升智能电网需求响应管理效率的同时,减少系统的运行成本。首先采用大规模天线的中心基站,保证智能电网需求响应的通信稳定性,然后通过低精度模数转换/数模转换(analog to digital conversions/digital to analog conversions,ADCs/DACs)提高通信系统的能量效率,同时中心基站采用全双工工作模式,进一步降低通信时延。仿真结果表明,在保障需求响应误差成本的前提下,低精度ADCs/DACs可以有效地提升通信网络的能量效率,以降低通信网络的运行成本。

Due to the operation cost of communication system was seriously affected by both energy efficiency and error cost of demand response of wireless communication,a ultra-dense network structure-based wireless communication network,by which the management efficiency of smart grid demand response could be lifted meanwhile the operation cost of the system could be reduced,was proposed.Firstly,a central base station with large-scale antennas was utilized to ensure the communication stability of smart grid demand response.Secondly,by means of low precision analog to digital conversions/digital to analog conversions(abbr.ADCs/DACs)the energy efficiency of communication system was improved,at the same time the full-duplex working mode was adopted to further reduce the communication time delay.Simulation result show that under the premise of ensuring the cost of demand response error the energy efficiency of communication network can be effectively improved by low precision ADCs/DACs to reduce the operation cost of communication network.
