Microgrids and Distributed Generation

Abstract

Applicationof individual distributed generators can cause as many problems asit may solve. A better way to realize the emergingpotential of distributed generation is to take a system approachwhich views generation and associated loads as a subsystem ora microgrid. The sources can operate in parallel to thegrid or can operate in island, providing utility power stationservices. The system will disconnect from the utility during largeevents (e.g., faults and voltage collapses), but may also intentionallydisconnect when the quality of power from the grid fallsbelow certain standards. Utilization of waste heat from the sourceswill increase total efficiency, making the project more financially attractive.University of Wisconsin laboratory verification of microgrid control concepts areincluded. 2007 ASCE
