Autonomous Local Control in Distributed DC Power Systems

202 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2006.Applications considered are supply-side and demand-side management. On the supply side, droop control is examined as a form of autonomous local control that adds damping to stabilize the power system. On the demand side, control strategies are shown for both single bus and multibus systems. In a single bus system, dynamic load interruption is shown to be useful to prevent voltage collapse, when demand exceeds supply, and to be capable of automatic load restoration upon system stabilization. In a multibus system, autonomous local controls can ensure reliable system operation by reconfiguring how the load is supplied to ensure seamless power transfer during fault conditions or partial loss of generation.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
