Özet
In this study, a novel interface topology called T-type isolated multi-port converter (T-iMPC) is proposed for integrating multi electric vehicles (EVs) with energy-consuming homes in DC microgrid. The proposed converter interface is purposed to use energy units of two different EVs for integration and supervise optimal energy flow between EVs and consumer homes. In the designed system, an FCEV and a BEV are implemented as energy units to manage electrical energy for the vehicle-to-home (V2H) concept. In this context, three energy flow modes are considered for the proposed system: (i) FCEV and BEV are suppliers, (ii) FCEV is supplier, BEV is consumer, and (iii) FCEV is the only supplier. In order to validate the efficacy of the converter operation, a control algorithm is developed to keep the output voltages at a balanced state. The proposed topology is examined under various case studies, including the dynamic load profile of homes for one day and different energy supply modes for FCEV/ BEV energy units. Besides, the proposed system is analyzed under various conditions. An assessment and comparison of efficiency involving existing topologies applied in V2H systems are also provided to show the benefits of the proposed converter interface for V2H system in different operating conditions.
