Abstract:

In a standalone DC microgrid connected with multiple renewable resources and storage elements, parallel dc-dc converters are more commonly used as interfacing unit between renewable energy sources and load. Current is shared between various power converters which are connected in parallel fashion to maintain a stable DC voltage in the grid. In order to ensure better load sharing in DC microgrid applications, droop control technique is more commonly used. But this control technique cannot ensure a decent level of voltage regulation. In order to address this problem, an improvisation is made in the conventional droop control strategy to obtain a better voltage regulation. This in turn improves the reliability of the system under various conditions. Proposed control technique is simulated and results are provided in this paper.
