    (IEEE, 2018-05) Gunaratne, T; Wijesinghe, D; Wijerathne, K; Binduhewa, PJ; Ekanayake, J; Chathuranga, D
    The 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.
