    A Measurement and Power Line Communication System Design for Renewable Smart Grids
    (DE GRUYTER POLAND SP ZOO, 2013) Kabalci, E.; Kabalci, Y.
    The data communication over the electric power lines can be managed easily and economically since the grid connections are already spread around all over the world. This paper investigates the applicability of Power Line Communication (PLC) in an energy generation system that is based on photovoltaic (PV) panels with the modeling study in Matlab/Simulink. The Simulink model covers the designed PV panels, boost converter with Perturb and Observe (P&O) control algorithm, full bridge inverter, and the binary phase shift keying (BPSK) modem that is utilized to transfer the measured data over the power lines. This study proposes a novel method to use the electrical power lines not only for carrying the line voltage but also to transmit the measurements of the renewable energy generation plants. Hence, it is aimed at minimizing the additional monitoring costs such as SCADA, Ethernet-based or GSM based systems by using the proposed technique. Although this study is performed with solar power plants, the proposed model can be applied to other renewable generation systems. Consequently, the usage of the proposed technique instead of SCADA or Ethernet-based systems eliminates additional monitoring costs.

    Analysis of the Use of Different Decoding Schemes in LDPC Coded OFDM Systems over Indoor PLC Channels
    (KAUNAS UNIV TECHNOLOGY, 2014) Develi, I.; Kabalci, Y.
    Power line communication (PLC) method is a developing technology that is intended to provide a communication platform by using conventional power lines. In this study, bit error rate (BER) performances of low-density parity-check (LDPC) coded orthogonal frequency-division multiplexing (OFDM) systems have been examined over indoor PLC channels. Performances of different LDPC decoder schemes such as belief propagation (BP), weighted bit flipping (WBF) and implementation-efficient reliability ratio based weighted bit flipping (IRRWBF) decoders were investigated in the modelled system. Different indoor channel scenarios that were generated by using new and more realistic PLC channel model proposal were also employed to evaluate the BER performance analyses. The performed simulations in the PLC channels showed that the LDPC codes can provide significant improvement with a remarkable encoding complexity when the BP or IRRWBF decoder is utilized on the receiver unit.
