Summary In recent years, power lines have gained significant interest for their use in high‐speed communications because of the already deployed power distribution infrastructure. However, to achieve high data rates with reliability in power line communication (PLC), robust signal processing techniques are required to mitigate channel distortion and noise. Orthogonal frequency division multiplexing (OFDM) as a multicarrier modulation technique has been standardized for PLC; however, to further enhance the quality of communication, wavelet OFDM (WOFDM) has been proposed as a suitable choice. In this article, OFDM‐based and WOFDM‐based PLC systems are studied, and overlap frequency domain equalization (OFDE) as a robust and efficient equalization technique is presented. Moreover, to enhance the efficiency of the OFDE, linear precoding (LP) is also suggested for fast Fourier transform and wavelet transform–based filter bank transceivers over the PLC channel. Performance of the proposed LP‐based OFDM‐OFDE and LP‐based WOFDM‐OFDE systems is compared with previously proposed equalization structures in terms of bit error rate, peak‐to‐average power ratio, and computational complexity via computer simulations. Furthermore, the performance of proposed architectures is also compared with classical equalization techniques under impulse noise with different intensities. Results show that not only the proposed LP‐based WOFDM‐OFDE transceiver performs better than the previous equalization models but also the LP‐based OFDM‐OFDE at the expense of slight increment in computational complexity.

“…The powerline communication (PLC) system has become prevalent in the modern day communication technologies assisting other forms of communication standards. It finds application in smartgrids and energy Internet [23]. PLC systems such as the IEEE 1901 standard uses Orthogonal Frequency Division Multiplexing (OFDM) [9], which can be deployed using wavelet transform [5,6] or fast Fourier transform [9].…”

“…In PLC systems, the periodic additive powerline noise may be categorized as being synchronous or asynchronous to the main powerline frequency [11]. In smart-grid networks in particular, PLC systems are perplexed with uncoordinated interferences emanating from neighbouring PLC devices and these may be grouped into the asynchronous impulsive noise (IN) [11,13]. These asynchronous interferences occur randomly in time and have high amplitudes.…”

“…These asynchronous interferences occur randomly in time and have high amplitudes. They may be mitigated using co-existence techniques [7,11] or by applying some memoryless nonlinearity pre-processing at the receiver [10,21,22]. In this study, we concentrate on the use of memoryless nonlinearity pre-processing at the receiver which can be enabled by clipping, blanking or their hybrid (blanking-clipping).…”

In future smart cities, smart grid technologies which are usually enabled by Powerline Communication (PLC) techniques are required. However, data transmission over powerline channel traverses a non-Gaussian media due to the presence of Impulsive Noise (IN) operating at the frequencies of PLC system which can be deployed using the IEEE 1901, that uses Orthogonal Frequency Division Multiplexing (OFDM). These OFDM signals have asymmetric amplitude distribution, which makes it difficult to identify and mitigate the IN presence. Converting the amplitude distribution to a uniform distribution can enhance the ability to mitigate IN when nonlinear IN mitigation techniques such as blanking is applied. In this study, we apply Iterative Clipping and Filtering (ICF) and companding schemes which are Peak-to-Average Power Ratio (PAPR) reduction techniques to enable symmetric amplitude distribution of the OFDM signals. With an optimization search for the optimal blanking amplitude for the two PAPR reduction schemes. Results show that companding scheme achieves 4dB gain in terms of received signal-to-noise ratio better than ICF after the blanking was used to remove the IN.

In recent years, wind plants have undergone major changes due to new technologies developed for smart grids (SG). For its success, it becomes necessary the use of modern information and telecommunication infrastructure with bidirectional data flow. In Brazil, due to the high penetration of data networks based on GSM technology (Global System Mobile), such as GPRS (General Packet Radio Service) and EGPRS (Enhanced GPRS), it has attracted the interest of energy companies to carry out the tasks of measurement, monitoring, and control in SG. The use of cellular technology enables at first a significant reduction in the SG deployment costs while providing reliability and security of the information. In this context, the use of a cellular network for monitoring and control data sharing in intelligent wind farms has recently aroused great interest. This work proposes the analysis of a wireless control system based on GPRS and EGPRS data services for variable-speed squirrelcage induction generators (SCIG) connected to the power grid. The wireless communication system is employed to send the reference power signals to the SCIG controller with the necessary reliability to ensure the power quality provided by the wind turbine. The performance of the proposed system is evaluated by several simulations and tests.
