“…An algorithm for intentional islanding of a power grid satisfying various islanding constraints was presented in [2], [3]. However the algorithm is not applicable to all networks and failed to keep the islands observable in some cases, as shown in the present paper.…”

“…Such a sectionalized system can then be restored gradually to normal operation once the fault is cleared thereby reducing the probability of a Grid blackout. The algorithm proposed in [2] and [3] is modified in this work for better observability of Islands and channel limit considerations are also incorporated. The original algorithm is explained briefly here and the modifications proposed are explained in the following section.…”

In case of a cascading failure, the power grid splits into uncontrolled islands before descending into blackout. Intelligent islanding is an important method to reduce the risk of blackout by preventing propagation of disturbance to other part of the system. Phasor measurement units are now integral part of a power system are very effective in detection of islanding. This paper presents an algorithm for power system intentional islanding to avoid the propagation of faults to healthy sections of the network in case of disturbances by using the synchrophasors measurement. The proposed algorithm has wider applicability and performs better in terms of network observability.

“…This policy has remarkably improved the grid discipline over a period of time. Reliability of generating units from protection side can be improved by the installation of synchronized phasor measurement unit (PMU) for wide area measurement [19,20]. India has installed and successfully operated its first PMU unit system in April 2010 in Northern Region Load Dispatch Center (NRLDC).…”

Indian power sector is at the third stage of reforms now, where energy security and advanced operation and control through new technology to build twenty first century power system is required. Government of India has set its Smart Grid Vision as a part of National Action Plan on Climate Changes.Accelerated Power Development Programme is a backbone and Restructured Accelerated Power Development Programme is a transition to Smart Grid. The Smart Grid Vision of India with three agendas as reliable generation,reliable and advanced distribution system and end of load shedding is explored through various policies and regulatory initiatives taken and milestones achieved. The historical development in institutionalization of the process is also presented. The key performance indices and scope of work is proposed in Indian Scenario to match the smartness of grid.

The Phasor Measurement Unit (PMU) is a contemporary metering device installed on system to enable the power system monitoring and control. PMUs are most accurate and advance time synchronized technology which provides measurements of voltages at the buses and also current phase values which are connected to those buses where these PMUs are located. PMU placement on each bus of a system is difficult to achieve either due to cost factor or due to non-existence limitation of communication facilities in some parts of the system. Moreover, as a consequence of Ohm's Law, when a PMU is placed at a bus, neighboring busses also become observable. This implies that a system can be made observable with a lesser number of PMUs than the number of busses. It is necessary to determine the minimum number of PMUs for entire observability of the power network. The optimal placement of PMUs (OPP) problem can be solved by various techniques. Hence in this paper a comprehensive review is presented on the OPP problems under the characterization of heuristic and mathematical methodologies. Also a comparison between
