Theme: Electrical systems reconfiguration and control

Keywords: fault tolerant control, fault tolerant converters, MLI strategies,  Supervision and control algorithms, power emulators, residential nanogrid, AC and DC smart microgrid, Demonstrator.

 Objectives:

1. Improve systems performances according to the application requirements under operational modes and conditions variations.

a.Design control for severe conditions of use
b.Develop models integrating complex phenomena (Ageing, degradation, etc…) and design control to decrease their negative effect).

2. Ensure continuity of system service under faulty conditions (faulty elements could be sensors, static converters, loads, etc.)

a.Develop fault detection and isolation algorithms,  and reconfiguration of the control and/or the system topology.
b.Develop reconfiguration algorithms for performances improvement during a degraded mode operation.

Application fields : Residential and nano grid residential, microgrid, mutilevel converters for renewable energy generation with HDVC link.

Tools : Emulators, Demonstrators, Digital Simulators
