Ekanayake, "AC-DC Multi-port Domestic Distribution Interface," 2018 Moratuwa Engineering Research Conference (MERCon), 2018, pp. 288-293, doi: 10.1109/MERCon.2018.8421902.http://dl.lib.uom.lk/handle/123/18740The rapid development of PV systems and energy storage techniques have created opportunities for further evolvements on the utility side. On the other hand, the number of conversion stages required to feed inherent and converter controlled dc loads from the ac grid have compromised the efficient operation of the power grid. The proposed multi-port distribution interface combines dc and ac power resources and dc and ac loads with minimum number of power electronic conversion stages thus increases the energy efficiency. This paper presents the development of the converters and the controller functions of the proposed interface which is to be implemented in a domestic scale. Along with the individual simulations the paper includes several case studies where different behaviors of the overall system are discussed.enPV SystemsEnergy Storage DevicesGrid SupplyAc-dc multi-port domestic distribution interfaceConference-Full-textEngineeringEngineering Research Unit, University of Moratuwa20182018 Moratuwa Engineering Research Conference (MERCon)Moratuwa, Sri Lankapp. 288-293Proceedings of 2018 Moratuwa Engineering Research Conference (MERCon)thilini.g@eng.pdn.ac.lkdhanujaya.wijesinghe@eng.pdn.ac.lkkanishkawijerathne.kw@gmail.comprabathb@ee.pdn.ac.lkjbe@ee.pdn.ac.lk10.1109/MERCon.2018.8421902
