   Abstract : Autonomous vehicles are a rising technology that aims to change the way people think about mobility in the future. A crucial step towards that goal is the assurance that malicious actors cannot instigate accidents that could lead to damages or loss of life. READ MORE

5. 9. Microgrid Safety and Protection Strategies

   University essay from KTH/Elektroteknisk teori och konstruktion

   Author : Aryudha Hartono; [2018]
   Keywords : IB-RES; grid-connected mode; islanded mode; short circuit; IED; directional zero and negative sequence current protection; unbalanced load flow; protection coordination; fault ride-through;

   Abstract : One of the challenging issues with the Microgrid is that the bidirectional power flow providedby the distributed generator (DG) which modify the fault current level. Furthermore, theinverter based-renewable energy source (IB-RES) limits the total fault current contributionto the grid due to its thermal capability. READ MORE
