With the decision to construct the smart grids around China, the power line communications (PLC) on the low-voltage (LV) distribution networks have become one of the potential technologies to commute the information between the end users and the power provider. Comprehensive and well-founded knowledge of the LV power line channel is the foundation to establish realistic modeling of the channel characteristics. The growing power line communication (PLC) technology is providing new potential for emerging applications such as G3 and Prime. In this paper, we have proposed a OFDM based channel sounding test bed to measure PLC channel within frequency band 100 kHz-2 MHz. A souding signal for the PLC channel is designed and a time-domain measurement method for the time-varying PLC propagation is presented. The experimental results of PLC channel characteristics under different scenarios are and analyzed.

Distributed Energy Resources might have a severe influence on Power Line Communications, as they can generate interfering signals and high frequency emissions or supraharmonics that may cause loss of metering and control data. In this paper, the influence of various energy resources on Narrowband Power Line Communications is described and analyzed through several test measurements performed in a real microgrid. Accordingly, the paper describes the effects on smart metering communications through MAC layer analysis. Results show that the commutation frequency of inverters and the presence of battery chargers are remarkable sources of disturbance in low voltage distribution networks. In this sense, the results presented can contribute to efforts towards standardization and normative of emissions at higher frequencies higher, such as CENELEC EN 50160 and IEC/TS 62749.

The design on the system of low-voltage power line carrier-current communication based on OFDM was finished in this paper. Then model of the system was simulated and the modulation and demodulation of OFDM were realized. The results show that the integral performance can be enhanced with channel code. And the bit error ratio (BER) of the system is different with several sub-carrier wave modulation modes. This system could satisfy the requirement of power line communication basically.

Simulation Results

The popularity of the Power Line Communication (PLC) system has decreased due to significant deficiencies in the technology itself, even though new wire installation is not required. In particular, regarding the request for high-speed throughput to fulfill smart-grid requirements, Broadband Power Line (BPLC) can be considered. This paper approaches PLC technology as an object of simulation experimentation in the Broadband Power Line Communication (BPLC) area. Several experimental measurements in a real environment are also given. This paper demonstrates these experimental simulation results as potential mechanisms for creating a complex simulation tool for various PLC technologies focusing on communication with end devices such as sensors and meters. The aim is to demonstrate the potential and limits of BPLC technology for implementation in Smart Grids or Smart Metering applications.
