This collective work, which includes the contributions of forty academic and industrial authors, is a reference document to discover Power-line communication PLC technology and learn about its latest developments, in particular, multi-sensor technique, or Multiple-Input Multiple -Output MIMO. Leave a comment. For a reliable communication and control, the communication technology used to implement the smart grid must have enough bandwidth to handle two-way data traffic. The technology must also be cost effective considering the sheer size and scale of electrical grids.
Power Line communications PLC is a promising communication protocols for cost effective, secure and reliable realization of smart grids. This paper presents a disquisition on smart grid technologies with emphasis on PLC technologies. The role of PLC in the application of smart grids over the different voltage networks is also covered. It is an excellent platform Established electric grids operate on a vertical structure of for delivering converged communication services, preparing power generation, transmission and distribution with limited for electric vehicles and implementing active consumer control and communication capabilities.
It is clear that the ICT platforms for realizing these power systems results in greenhouse gases emission and smart grids will consist of a combination of technologies and has a low level of security of supply [1, 2]. Vertically software solutions. For smart metering and communications integrated power systems initially use Carrier Frequency applications, key technologies include wireless networks, System CFS for internal communication, remote optical fiber, and internet based technologies [7, 8].

MIMO Power Line Communications: Narrow and Broadband Standards, EMC, and Advanced Processing
Direct access to the utility assets and is primarily responsible for remote measurement and control electricity meters can be realized using internet based of the power system using distributed Remote Terminal Units technologies such as public broadband access and PLC. The RTUs obtain digital data from Intelligent Furthermore, rapid advance in hardware and software Electronic Devices IEDs , which usually consist of development will continue to support more ICT based microprocessor based equipment such as transformers, circuit platforms for active distribution networks, micro grids, energy breakers and capacitor banks.
The SCADA system is also used storage, and grid asset management among other applications for monitoring and control of analogue data associated with . EMS provides software platforms for optimization and control of the electric power system. Some applications of EMS include load forecast, restoration strategy, optimal power flow, economic dispatch and dynamic security assessment .
The major drawback of the SCADA system is the high latency associated with its architectural model coupled with the asynchronous manner in which measurements are captured in the system. In order to implement the various communication and control systems, efficient communications systems are indispensable.

Consequently, the power spectral density covering the spectrum of Ultra Narrowband, Low Data Rate is not constant over the transmission domain, which makes Narrowband, High Data Rate Narrowband and Broadband Communications. The platform for PLC is a cyber — physical reception of signal more challenging. The most important 3 Type 1 noise otherwise known as coloured background noise alternative to PLC for implementing WAN is the use of is characterized by a low spectral density which tends to wireless network infrastructure such as WiMAX Worldwide decrease with increase in frequency.
Type 2 noise narrowband Interoperability for Microwave Access and LTE, which offers noise is a background noise that is caused by amplitude extensive coverage and large bandwidth but must be rented at modulated AM signals especially from broadcast stations.

Some applications impulses results from switching transient circuits in the over the NAN and HAN networks include: substation networks. Type 3 noises have a very network topology, frequency and time. There are two high repetition rate which allows its frequency to be established methods that can be used for the channel approximated as a narrowband spectrum. Thus Type 2 and characterization of high frequency PLC channels namely: measurement based approach and intrinsic parameters Type 3 can be approximated as background narrowband noise approach.

Considering the serious impact of impulsive noise on is illustrated in Fig. The characteristic impedance of the line is expressed as: 2. Some factors affecting the topologies of LV power supply networks include : Network location, subscriber density, network length, and network design. Subscriber density refers to the number of users attached to a voltage network. Network design considers network factors such as segmentation, cabling as well as the type of topology: radial, ring or interconnected. Channel noise, impedance and attenuation are unpredictable and stochastic.
