Frede BlaabjergMoving Forward With the Baton

 by Frede Blaabjerg

From 1985 to 1987, I was a master’s student at Aalborg University, Denmark, working with power electronics and field vector-oriented control of electrical drives. The switching frequency was 20 kHz to make the drive silent, and we were using a combination of MOSFETs and bipolar transistors to obtain such speed in the power stage. Simultaneously, by sampling around 5 kHz, the processor was pushed to the limit by using the Assembler software. At that time, all of the technology we utilized was the state of the art.  Read More...

Ehab ShoubakiAbstract: Currently the bulk of energy generated from fossil fuels, nuclear, geothermal, hydro and some wind resources interface with the grid through rotary machines. An ever-increasing but small portion of generation comes from renewable energy resources distributed across the network that are harvested and dispatched into the grid by power electronics. It is well understood that increased penetration of renewable DERs introduces power quality and system-wide stability issues. This webinar explores the effect of classically controlled DERs on grid stability and future directions for achieving autonomous grid forming capability with power electronics. Read more...
