A survey on smart grid communication systemmiles h.f. wen 1 , ka-cheong leung 1 , victor o.k. li 1 , xingze he 2 and c.-c. jay kuo 2Concerns with global warming prompted many governments to mandate increased proportion of electricity generation from renewable sources. This, together with the desire to have more efficient and secure power generation and distribution, has driven research in the next-generation power grid, namely, the smart grid. Through integrating advanced information and communication technologies with power electronic and electric power technologies, smart grid will be highly reliable, efficient, and environmental-friendly. A key component of smart grid is the communication system. This paper explores the design goals and functions of the smart grid communication system, followed by an in-depth investigation on the communication requirements. Discussions on some of the recent developments related to smart grid communication systems are also introduced.

Communication Requirements in Microgrids: A Practical Survey

“…Four main functions are necessary to accomplish proper MG operation: advanced monitoring and control (AMC), system protection (SP), demand-side management (DSM), and generation and storage management (GSM) [55]. Depending on the MG structure and operation requirements, some of these functions can be deployed within the EMS [56].…”

“…By replacing a network controller as a single point of failure with ad hoc communications, the reliability of MGs is increased. Nevertheless, given that security is a growing concern, there are recommendations [55], and field implementation examples [76] that use two separate communication networks in S-MGs: one for communication control and the other, physically or logically separated, for the telemetry/data acquisition service network.…”

Software Based Experimental System for Electrical Power Quality Measurement Using the Wireless Sensor Network Modules

“…Today, there is an enormous effort to introduce the concept of smart grids in production, distribution and consumption of electrical power, in order to improve energy efficiency level, reliability and stability of power distribution networks [9,10]. Power quality is very important issue in modern electrical power networks and smart grids, especially at the end consumers in the low voltage distribution networks.…”

Vulnerability Assessment and Experimentation of Smart Grid DNP3

“…Security concerns in the energy sector will be our key driver and the smartgrid technologies will be our primary focus in this research paper. Physical and cyber security are using both physical and cyber components integrated with both legacy systems and new technologies running over TCP/IP platform [1]. Legacy Supervisory Control and Data Acquisition (SCADA) [2,3] were initially designed to be isolated systems that had both dedicated and separate communication links and therefore cyber or physical security was never considered to be a threat.…”

“…Legacy Supervisory Control and Data Acquisition (SCADA) [2,3] were initially designed to be isolated systems that had both dedicated and separate communication links and therefore cyber or physical security was never considered to be a threat. Today's systems [1] and [4][5][6] demand a much higher level of communication to be available in smart-grid automation systems involving components like Intelligent Electronic Devices ( 1 IED's). IEDs [7,8] are designed to automate protection, control, monitoring and metering for the smart grid system in both peer-to-peer and client server implementation.…”
