The increasing consumption of the electric energy aimed at develop transmission networks and demand for higher reliability from network; in this regard, wide-area measurement systems using phasor units (PMUs) have revolved trend power network management. In paper, optimal allocation PMUs order to reach perfect observability based on a differential evolution algorithm, is proposed it shown that,...

The phenomenal growth of power system network both in terms of geographical sprawl as well as technological advancements, it requires tools for dealing with the system, wide disturbances that often cause widespread catastrophic blackouts in power system networks. When a major disturbance occurs, protection and control measures play the most important role to prevent further degradation of the s...

ue to the expansion of power systems there is a challenge of real time monitoring and control by placing important parameters at various points for efficient functioning of the power system. There can be drastic changes during hourly load fluctuations, component outages, or network switching. In such conditions, the inclusion of predicted values could degrade the power system state estimation h...

Phasor data concentrators (PDCs) are the critical components of a wide area monitoring system (WAMS) in the smart grid. They are multi-processor devices employed to collect, concentrate, and synchronize phasor data that is from various phasor measurement units and from other PDCs. Because of their present significance and potential criticality for WAMS, reliability of PDCs has become a high pri...

An alternative and simplified procedure is described to estimate the longitudinal resistances of transmission lines based on the real-time load profile. This method proposes to estimate the resistance parameters from the synchronized measurements of complex currents and complex voltages at the sending and receiving ends of transmission systems. The synchronized measurements can be in practice o...
