This paper focuses on control and operation of a small-scale residential dc microgrid supplied by photovoltaic array (PVA), fuel cell (FC) and super-capacitor (SC). The control scheme aims to realize the optimal power allocation, protect FC from fuel starvation, and stabilize dc bus voltage. The dc microgrid can operate in both islanded and grid-connected mode. To make the system work properly during islanding operation, power control and energy management strategy are proposed. When system is grid-connected, power balance is achieved by controlling the threephase voltage source rectifier (VSR). The effectiveness of the proposed control method is verified through simulations.

W artykule skupiono się na zagadnieniu sterowania mikro-siecią DC małej skali w zastosowaniu mieszkaniowym, zasilanej z systemu złożonego z paneli fotowoltaicznych (ang. photovoltaic array), ogniw paliwowych (ang. fuel cell) oraz super-kondensatora (ang. super-capacitor), z naciskiem na optymalizację rozpływu mocy, zapewnienie dopływu paliwa dla ogniw paliwowych i stabilizację napięcia DC. Przeprowadzono analizę symulacyjną algorytmu, gdzie rozważono przypadki pracy wyspowej i podłączenia do sieci energetycznej.
