The present-day power system is a complex network that caters to the demands of several applications with diverse energy requirements. Such a complex network is susceptible to faults caused due to several reasons such as the failure of the equipment, hostile weather conditions, etc. These faults if not detected in the real-time may lead to cascading failures resulting in a blackout. These blackouts have catastrophic consequences which result in a huge loss of resources. For example, a blackout in 2004 caused an economic loss of 10 billion U.S dollars as per the report of the Electricity Consumers Resource Council. Subsequent investigation of the blackout revealed that the catastrophe could have been prevented if there was an early warning system. Similar other blackouts across the globe forced the power system engineers to devise an effective solution for real-time monitoring and control of the power system. The consequence of these efforts is the wide area measurement system (WAMS). The WAMS consists of several sensors known as the phasor measurement units (PMUs) that collect the real information pertaining to the health of the power grid. This information in the form time synchronized voltage and current phasors is communicated to the central control center or the phasor data concentrator (PDC) where the data is analyzed for detection of power system anomalies. The communication of the synchrophasor data from each PMU to the PDC constitutes the synchrophasor communication system (SPCS). Thus, the SPCS can be considered as the edifice of the WAMS and its reliable operation is essential for the effective monitoring and control of the power system. This paper presents a comprehensive review of the various synchrophasor communication technologies, communication standards and applications. It also identifies the existing knowledge gaps and the scope for future research work.

“…Latency requirements for real-time control of distribution networks remains a key research area. The complexity of coordinating remote inputs requires additional constraints and a systematic method to ensure that the use of distributed inputs for control can outperform locally available information [19]. Time latency tolerances can be variable and dependent upon power system characteristics and control schemes but are generally on the order of milliseconds for distributed generation.…”

Executive SummaryCorrect time and timing is one of the foundational elements in enabling the communication and orchestration of technologies for accurate and optimal wide area monitoring, protection and control (WAMPAC) in the power industry. The National Institute of Standards and Technology (NIST) and the International Electrical and Electronic Engineer -Standard Association (IEEE-SA) conducted a workshop to gather inputs from stakeholders to identify, analyze, and provide guidance on technologies, standards and methodologies for addressing the practical timing challenges that are currently being experienced in wide area time synchronization.One of the key drivers for the workshop is the need to prioritize NIST efforts in addressing precision timing needs in power systems. NIST has established a Smart Grid Testbed, which includes the Precision Timing module to support the IEEE 1588 Power Profile efforts and to serve as a basis for timing measurement and security research. The objective of the workshop was to identify the timing challenges, the community of experts, and potential collaborators as well as key research priorities to guide future efforts to ensuring that the integrity, availability, accuracy, and precision of timing requirements are met in power systems.Precision timing synchronization with requirements ranging from one microsecond to hundreds of nanoseconds within and across substations is currently being characterized and monitored by utilities in order to advance capabilities in real-time measurement and control and to reap the economic and environmental benefits of more intelligent and efficient use of generation and storage resources while meeting customer demands. The proliferation of widely deployed smart sensors for WAMPAC, distribution and energy management systems, along with the increasing need for fault detection and location as well as maintaining system stability in real time using spatio-temporal and temporalfrequency analyses, all require precision timing. These new capabilities offer increased flexibility to grid operators, but they also raise new security concerns.Among the concerns expressed include timing discontinuities such as leap seconds, Daylight Savings Time, and GPS Week Number Rollovers. Additionally, the increasing prevalence of jamming and the potential for spoofing is leading security, time and network experts in power systems or other domains to explore alternative propagation methods of traceable time. These include eLOng-RAnge Navigation (eLORAN), Iridium, IEEE 1588 Precision Time Protocol (PTP), Network Time Protocol (NTP), radio (WWVB is the NIST operated time signal radio station near Fort Collins, Colorado.), atomic clocks, and other terrestrial and satellite-based timing propagation solutions.Given the current stage of exploration and characterization for real time control, utilities and system integrators identified the top industry challenge to be integrity assurance, with the first steps being device conformance and interoperability testing, performance mo...

“…The principle of development of Information and Communication Technology (ICT) is the principle of infrastructure development, meaning that this development can touch various basic aspects such as skill development and behavioral skill. Anh, et al [1] argues skills for insightful archipelago along with the accompanying aspects. According to Vijay, et al [7] the ability and individual skills in dealing with change needs to be addressed as a major action in the development of a teacher's career process and the development of character education quality.…”

The purpose of this study is to measure the achievement of IT-based learning in remote areas. The approach in this research uses ethnographic research with interview-based participatory observation method. The result of this research are: (1) the process of identity development and development process, although done to process the creation of an adequate learning development process; (2) the development of character values needs to be maintained in developing a character education process integrated with distance learning conducted by stakeholders; and (3) to develop the learning process in the network, learners are even involved in creating real work for the community. Suggested to the stakeholders for: (1) Development of learning in ICT-based network although developed based on the principle of independence and convenience; the process of developing ICT learning basically needs to be developed based on the needs of learners; and (2) the 21st-century learning culture is a learning culture based on learning in the network. Development of learning in the network though reaching the whole region is no exception remote areas.
