Cooperative Wireless Transmission for Smart Metering

摘要

In order to optimize the power consumption and improve the energy efficiency, the smart grid (SG) provides reliable, efficient and secured electrical power generation and distribution. Smart grid aims to manage and control the consumer demand and provide the needed power. Thus, in smart grid architecture, the information about power supply must be known, in advance, by the operator. This information exchange is generally ensured through wireless communications. In the communication infrastructure, there is no place for transmission errors and high reliability is required. Also, a beforehand estimation of the next minutes consumption is desirable, to prepare the production, especially in the presence of distributed energy resources. In this paper, a Cooperative Wireless Transmission of Smart Metering called (CWT) is proposed to improve the transmission quality by reducing transmission errors and time delays. The objective is to gather the total of power consumption demand from every consumer and convey it simultaneously through a DAP (Data Aggregation Point) to the control center. Simulation results shows that CWT scheme outperforms the time division multiple access (TDMA) in terms of Cooperative Symbol Error Rate (CSER) and Power Metering Delay (PMD).
