The measurement system called Phasor Measurement Unit (PMU) can be used to better observe, control and protect the power grid but at the transmission level. However, the existing PMU has been adapted to be used in distribution network integrating renewable energies (smart distribution network), which needs a high-precision power measurements. The adapted PMU is named micro-Phasor Measurement Unit (μPMU) that can store synchrophasor measurements and communicate real-time data in distribution level of the power grid.

This keynote presents two main points:

1) Development of μPMU with precise time stamping of measurements via GPS to allow the comparison of voltage phase angle δ (i.e., the precise timing of the voltage waveform) at different locations, on hardware side. On the software side,  development of a new computational framework to manage large, high-density data streams with nanosecond time stamping and online capabilities that avoids the need for phasor data concentrators.

2) Development of many practical applications using this new type of information provided by μPMU in the distribution network context including the integration of intermittent renewable generation such as distributed control, adaptive protection and cyber-security of the electric grid.
