摘要：
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 three-phase voltage source rectifier (VSR). The effectiveness of the proposed control method is verified through simulations.
