The transition from fossil fuel-based energy sources involves exploring different sources of energy that can be reliably integrated into the power grid. One such existing resource is the CHPs, which are distributed throughout the US electric grid. The integration of the CHPs into the grid requires technological innovations. One idea is to design an F-CHP converter that would facilitate the CHPs to interconnect seamlessly with the electrical grid. This thesis presents the development and testing of different components of a testbed that would facilitate the testing of the F-CHP converter. It also presents the integration of a PMU and a communication interface for the F-CHP converter. The phasor estimation of the F-CHP PMU has been compared with a commercial PMU and its performance has been validated. / Master of Science / The transition from fossil fuel based energy sources involves exploring different sources of energy that can reliably integrated into the power grid.

<p>У дисертацији је дат концепт микро мрежа и описане постојеће методе у управљању и оптимизацији рада микро мрежа. Предложен је нови централизовани контролер микро мрежe заснован на технологији више-агентног система, који омогућава координацију три режима рада (повезани, острвски и хаваријски) и обезбеђује једноставну конфигурацију и комбинацију оптимизационих критеријума, уз уважавање широког скупа ограничења. Предложени модел примењен је на релевантни тест систем и резултати су приказани уз одговарајућу анализу резултата.</p> / <p>U disertaciji je dat koncept mikro mreža i opisane postojeće metode u upravljanju i optimizaciji rada mikro mreža.
