Voltage and Reactive Power Control in Islanded Microgrids
… put on view lots of advantages and concerns for islanded microgrids (IMGs), whether it is initiated for emergency, intentionally planned or permanent island system purposes. From the concerns that have not been addressed yet, such as: 1) The ability of the distributed generation (DG) units to …

Fuel-conserving environmental control strategies for small Islanded microgrids
In this thesis I designed and deployed a control system that subjects Environmental Control Units (ECUs) at U.S. Army Forward Operating Bases (FOBs) to centralized control, and demonstrated how intelligent operation of the ECU load can result in considerable fuel savings. I also developed a …

Power Sharing and Power Quality Improvement in Parallel Connected Power Converters in the Microgrid
… can effectively share the load power demand in islanded microgrids as well as actively mitigate the resonances and harmonics in grid-connected mode. A modified droop control method with a minimum number of current sensors is investigated to accurately share the active and reactive power demand …

Consensus-Based Active and Reactive Power Control and Management of Microgrids
<p>Microgrids incorporating distributed generation and renewable energy sources offer potential solutions to the energy crisis while modernizing traditional grids. Despite cost-effectiveness in some technologies, financial support remains crucial for expensive ones like PV, fuel cells, and storage …

Islanded Operation of Parallel Inverter-interfaced Microgrids with Photovoltaic Systems
… share power proportionally in inverter-connected islanded microgrids; in which different microgrid structures such as inductive (L-type), resistive (R-type), and resistive-inductive (RL-type) are considered. The main aim of designing new controllers in this dissertation is to distribute the load …

Risk Assessment and Optimal Response Strategies for Resilience of Electric Power Infrastructure to Extreme Weather
… of a storm’s landing, and the joint operation of islanded microgrids and repair of damaged components in the post-storm stage. The failure scenarios in this formulation are drawn from our physically-based damage model. The key challenge here is that the size of the optimization problem increases …

Optimal and resilient management of distributed energy resources
… also been facilitated through the deployment of microgrids. Despite their relatively small physical footprint, achieving stable operation of microgrids requires addressing certain stability issues that are far less prevalent in the bulk power grid. In contrast with the bulk power grid, microgrids …
