In a smart power grid integrating different renewable energy sources, conventional monitoring, control and protection systems based on local independent measurements and decisions are not able to consider the overall power grid disturbances and then they are not able to avoid the blackout. The introduction of the advanced Phasor Measurement Unit (PMU) and communication technologies in these grids may provide better ways to detect and monitor rapidly these disturbances and hence protect the overall grid from the propagation of the fast-cascading outages. This talk presents three main points: 
1) Micro-Phasor Measurement Unit: This type of PMU has been developed for Active Distribution Network that can be found in the smart grid. The Micro-PMU is an improvement of PMU performance that can measure real-time dynamic parameters of the distribution part of power system with high precision. It is very suitable for power grid integrating any kind of renewable energy sources. 
2) Application of PMUs to Smart Grid Protection: Some protection systems based on PMUs in the smart grid will be described. Overcurrent relaying system can be enhanced by the information provided by PMUs where both parts of the reliability (security and dependability) can be improved.  
3) Application of PMUs to Smart Grid Control: Moreover, one other class of PMU application in control will be described such as the adaptive centralized load shedding scheme. The advantage of this method is that the amount of load to be shed is not large for all the disturbances unlike the conventional one. Therefore, unnecessary shedding can be avoided which allows both a better service to different consumers and the system collapse prevention.

Pr. Hamid Bentarzi has been faculty member at the Institute (IGEE), University M’hamed Bougara, Boumerdes, Algeria, since 1998. Now, he is full professor in electrical engineering. Besides, he received Bachelor degree in electrical engineering and M. Phil degree in applied Electronics from INELEC, Boumerdes, in 1989 and 1992 respectively. However, he defended his PhD degree in Micro-electronics at the school of engineering ENP, Algiers, in 2004. His research activities are centered upon control and protection systems reliability enhancement using the recent developed technologies. Moreover, he has authored and co-authored more than150 papers and two books.
