Abstract
In this paper, a loss optimized and cost effective droop control scheme is proposed for a DC microgrid coupled to a weak rural distribution grid. The active power exchange limits between the DC microgrid and the utility grid have been derived considering the Indian voltage regulation standards as set by Central Electricity Authority at the point of common coupling. In the grid-connected mode, the DC microgrid is connected to the utility grid via a bidirectional interfacing converter (BIC). The proposed scheme ensures an optimal operation of battery energy storage converter (BESC) and BIC in terms of loss and cost. The scheme employs a dedicated communication link based on controller area network (CAN) protocol making the system operation smarter and intelligent. The method guarantees the maintenance of the DC bus voltage at the nominal value under all operating scenarios. The performance of the control scheme has been validated with experiments. Case by case experimental results included.
