Time-Synchronized Measurements and Applications for Monitoring of Intelligent Electric Power Systems

For the future smart grid, time-synchronized measurements such as synchrophasor and advanced metering infrastructure (AMI) have been introduced into the existing power grid, which are featured by communication capabilities and higher measuring resolution contrary to the conventional measuring devices. These capabilities will enable us to monitor the grid in real-time manner for efficient and reliable operation of smart grid. In addition, these devices are considered as main sources to generate power system big data for intelligent smart energy services. This paper presents current status of time-synchronized measurements and their applications in big data. Moreover, applications and potentials in power system application are discussed when synchrophasor and AMI are time-synchronized across layers.
