Abstract	:	This dissertation investigates local control techniques that are applied to individualcomponents in a dc power system. These local controls operate autonomously using locallyobtained information, sensed at their respective components. Yet, they contribute to overallsystem stability without requiring a central controller or peer-to-peer communication network.In the event of a disturbance in the dc system, whether ephemeral or cataclysmic, autonomouslocal controls enable the system to self-heal in the sense that unaffected components stilloperate. Load priority ensures that if energy is limited, the most important loads havepreferential access. Limited system knowledge, such as the overall health of the system orchange in mission objective, can be used to fine tune the controller performance. However,the controllers still operate autonomously if access to this information is lost. These controlsare ideal for high-reliability, advanced energy systems since they can perform system-levelcoordination and are fault-tolerant.Applications considered are supply-side and demand-side management. On the supplyside, droop control is examined as a form of autonomous local control that adds damping tostabilize the power system. On the demand side, control strategies are shown for both singlebus and multibus systems. In a single bus system, dynamic load interruption is shown to beuseful,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
