Experimental test bench for testing DC microgrid control strategies
(IEEE, 2017)
During the last decades the number of microgrids and their research have increased notably, as they offer a high versatility for the integration of distributed generation (DG) units and renewable energies. Among the different ...
Comprehensive analysis of voltage balancing techniques for 5L NPC converters
(IEEE, 2013)
The reduced capability of the 5L-NPC Inverter to balance the voltages of the four DC-bus capacitors makes this converter unattractive for real power applications. This is especially true if the load demands active power. ...
Optimising Maintenance: What are the expectations for Cyber Physical Systems
(IEEE, 2016)
The need for maintenance is based on the wear of components of machinery. If this need can be defined reliably beforehand so that no unpredicted failures take place then the maintenance actions can be carried out economically ...
