Interlink Converters in DC nanogrids and its effect in power sharing using distributed control
Smart DC micro/nanogrids have become subject of much attention in recent years due to the increased interest in adding renewable energy sources and electric vehicles to residential and small buildings. Hybrid nanogrids with multiple buses present the potential of supplying different loads with more suitable power. In order to control the power flow between buses, interlink converters are used and appropriate control strategies are required so as to improve the performance of a hybrid nanogrid in terms of power quality (voltage regulation) and energy management in the buses using distributed control strategies. The main goal of this paper is to compare the performance and power sharing in a dual DC nanogrid 48 V 380 V interconnected by an Interlink Converter using two control strategies, namely average droop and constant voltage ratio. Simulation results are presented.
