Organization within the L.S.E

The L.S.E research program for 2016-2019 period is divided into two projects: AmPer and CoReR

The Qehna group is responsible for the AmPer project and is actively participating in the CoReR project through its investigations in the field of microgridss and multilevel converters for HVDC links.

CoReR : Conduction of grid and micro-grid integrating renewable energies
AmPer : Performance enhancement and fault tolerance of electrical systems
