Breaking the Hierarchy: Distributed Control & Economic Optimality in Microgrids

by John W. Simpson-porco, Francesco Bullo
"... Abstract—Modeled after the hierarchical control architecture of power transmission systems, a layering of primary, secondary, and tertiary control has become the standard operation paradigm for microgrids. Despite this superficial similarity, the control objectives in microgrids across these three l ..."

of steady-states reachable by droop control. In other words, the adoption of droop control is necessary and sufficient to achieve economic optimization. This equivalence results in simple guidelines to select the droop coefficients, which include the known criteria for power sharing. We illustrate

Optimization and Control of Cooling Microgrids for Data Centers

by Rongliang Zhou, Zhikui Wang, Alan Mcreynolds, Cullen E. Bash, Thomas W, Christian Rocky Shih - Proceedings of ITherm , 2012
"... Abstract — Reliable operation of today’s data centers requires a tremendous amount of electricity to power both the IT equipment and the supporting cooling facilities. As much as half of total data center electricity consumption can be attributed to the cooling systems required to maintain the therm ..."

cooling schemes. The various cooling resource options, together with the mechanisms to distribute and deliver the cooling resource to IT equipment racks, constitute a cooling microgrid. In this paper, we present a holistic perspective for the optimization and control of the data

Economic energy distribution and consumption in a microgrid

by Part Macrocell Level Controller, F. Tahersima, J. Stoustrup, P. Andersen, P. P. Madsen
"... Abstract: Energy management of a small scale electrical microgrid is investigated. The microgrid comprises residential houses with local renewable generation, consumption and storage units. The microgrid has the possibility of connection to the electricity grid as well to compensate energy deficit o ..."

. The top level energy manager is designed to distribute available power resources among the houses or sell the remainder to the electricity grid. Simulation results show the economically optimal energy consumption in the buildings and economically efficient power trading between the houses.

Plug-and-Play Control and Optimization in Microgrids

by John W. Simpson-porco, Francesco Bullo
"... Abstract — A hierarchical layering of primary, secondary, and tertiary control is the standard operation paradigm for bulk power systems. Similar hierarchical decision architectures have been proposed for microgrids. However, the control objectives in microgrids must be achieved while allowing for r ..."

Robust Energy Management for Microgrids With

by High-penetration Renewables, Yu Zhang, Student Member, Nikolaos Gatsis, Georgios B. Giannakis
"... Abstract—Due to its reduced communication overhead and ro-bustness to failures, distributed energy management is of para-mount importance in smart grids, especially in microgrids, which feature distributed generation (DG) and distributed storage (DS). Distributed economic dispatch for a microgrid wi ..."

1 A Centralized Optimal Energy Management System for Microgrids

by Daniel E. Olivares, Claudio A. Cañizares, Mehrdad Kazerani, Senior Member
"... Abstract — The issue of controlled and reliable integration of distributed energy resources into microgrids and large power grids has recently gained considerable attention. The microgrid concept, which basically corresponds to the coordinated operation of a cluster of loads, distributed generators ..."
