A novel approach in multi-port DC/DC converter control

Abstract

DC networks and storage systems are able to guarantee high reliability and continuity of supply to DC loads. They are also easily connectable to the majority of renewable sources, such as PV plants, due to the fact that they already work in DC. In this paper a multi-port DC/DC converter topology and a new control strategy are proposed. Following definition of each port's aim, the management algorithm (based on voltage droops) permits control of the power flow among ports, even if some of them are not working.
