“…In recent years, new energy supply concepts have been introduced. One of them newly introduced in renewable energy systems are smart grid concepts [13][14][15]. In addition, nowadays power-engineering field is facing huge challenges since the growing interest in intermittent renewable energies impose a whole new paradigm of operation.…”

This chapter present one possible evolution is the parallel topology on the high-voltage bus for the renewable energy system. The system is not connected to a chain of photovoltaic (PV) modules and the different sources renewable. This evolution retains all the advantages of this system, while increasing the level of discretization of the Maximum Power Point Tracker (MPPT). So it is no longer a chain of PV modules that works at its MPPT but each PV module. In addition, this greater discretization allows a finer control and monitoring of operation and a faster detection of defects. The main interest of parallel step-up voltage systems, in this case, lies in the fact that the use of relatively high DC voltages is possible in these architectures distributed.PLC systems are installed in HVDC lines using clean inter-wafer circuits, used for insulation and impedance between the DC-DC converter and the power grid. It is possible to view PLC systems as an additional part of each converter, without modifying its basic structure. Nevertheless, the two main steps are driven by a common microcontroller peripheral interface (PIC) controller assuming both the controller's master-slave tracking and control functions. This system is required for communication in small and medium power systems, such as remote reading, fire/ fire alarm control and shutdown. The system is designed with a digital modulator [19] to reduce the workload of the main controller of the DC-DC-PLC converter. These are two independent steps and a single control output reduces the cost of the entire system significantly. PLC system design on the HVDC busRenewable system manufacturers' energy products increasingly differentiate their products by providing more sophisticated and inventive features such as safety, stability, control, comfort, convenience and performance. However, the use of these applications requires high volume data exchange and a reliable data communication network to enable efficient and efficient control over electronic devices. On the other hand, conventional infrastructure systems and distributed decentralized power generation systems transmit on high voltage lines, the PLC system does not affect the quality of energy transmission of the system. In addition, the nodes of the PLC slaves will be integrated in the DC-DC converter corresponding to each generator. Therefore, the design of the PLC system on the high voltage line is the simple, economical and reliable signal transmission.In order to simplify and standardize the electrical system of the renewable energy generators on the HVDC bus, a number of communication standards and protocols have been proposed. Most communication systems on the HVDC bus are modified based on existing commercial communication technologies to meet the HVDC bus automation requirements such as high stability and error correction capability. In general, almost all networks for the HVDC bus are digital networks because of its high stability in terms of noise protection and error correction capability. From distrib...

“…An exhaustive amount of information Page 4 of 6 PV module maximum power point (MPP), which can be detailed by electrical measures like PV module voltage, PV module current and DC bus voltage directly realized by optimizers (as shown in Figure 3b). Tests have consisted in exchanges between the master and two slave units by reading of the slave sensors, the number can extend for the module slaves correspond with the number of the DC-DC converters connect parallel on DC bus [13][14][15][16][17]. A simple potentiometer has been used as an analog sensor and, after ADC conversion, the measurement transferred in a 16 bits format via the DC bus.…”

The multi-sources nature of renewable energy production can be taken into account thanks to involving the solutions of distributed architecture based on individual DC-DC converters, connected to a direct current (DC) bus. Associated to this architecture, to assume simply the communication between the modules, one solution is the use of the DC bus power bus to support the communication between optimizers and a central controller using a power-line communication approach (PLC). The current work consists, at first, in the analysis of the pertinent information necessary to exchange between DC-DC converters and a central controller and, at second, by the development of a new hardware solution for the PLC from the conception of the communication system to the realization of a prototype. The various possible devices connected on the bus or networks are considered as programmable logic controllers, various sensors, microcontrollers and grid inverters. At minima, the information to exchange between the various devices may include the maximum power point of photovoltaic modules (MPP) and the temperature of the individual sources. At first, the ASCII Modbus protocol was chosen in the present work to assume the PLC communication on the DC bus. The interfacing circuitry between the DC bus and PLC controller is achieved by TRSV04 transceiver and power coupling circuit. about the protocol is given on the website [8,9]. Referring to those documents the ASCII mode protocol for PLC slave and master was developed and tested successfully. Experiments consisted in reading two slaves connected to HVDC bus. Reading frames sent by master were composed of thirteen ASCII characters, including longitudinal redundancy checksum byte (LRC), necessary to exchange dependability. As shown in Figure 2, the response frame from slave was composed of fifteen ASCII characters, with the need to compute LRC byte depending on the value of transmitted data before response frame sending. The ASCII characters are described below: Power Line Communication System for Grid Distributed Renewable EnergyReading frame:• Reading request • Momery words address to read• Carriage return and line feedResponse frame:• Reading request • Number of bytes• 6 blank bytes • Carriage return and line feedIn the response frame the blank characters are replaced by the four ASCII characters of the two read data bytes added with the computed LRC.Obviously, received LRC byte was always compared to compute one's, both for master and the two slaves. So LRC byte allows to checked frame integrity: thanks to all this mean possible serious disturbances on DC bus can be instantaneously detected as it was done in our power line communication design on the DC [10][11][12]. Available baud rates are limited by the carrier wave frequency (maximum baud rate equal to about 10% of the carrier frequency) to take account of the receiver filter delay group, and DC power line impedance. Concerning the microcontroller, the only limitations are the highest baud rate of the universal synchronou...

Heterogeneous and hybrid smart grid communication network is a network that comprises of different communication mediums and technologies.Performance evaluation is one of the main concerns in smart grid communication system. In any smart grid communication implementation, to determine the performance factor of the network, a testing of an end-to-end process flow is required. Therefore, an effective testing tool plays a crucial role in evaluating the performance of smart grid communications. Ping is currently one of the most widely used tools. In this paper, a customized ping utility, called Smart Grid Ping, is introduced. This utility provides random ping intervals with user selectable distribution, allowing network administrators to test the reachability and availability of various applications in smart grid communication system.
