This paper proposes a converter control method for the system interconnection of an electric vehicle power conditioning system (EVPCS). The proposed system applies cooperative control of the DC link voltage and system power control capable of suppressing the reverse power flow to enable seamless charge and discharge of the EVPCS. The results of both the simulation and experimental verification using an actual equipment demonstrated that the proposed system successfully suppressed the reverse power flow and follow up on the power commands while the EVPCS did not stop due to sudden changes in the load power or significant changes in solar power generation in the photovoltaics.
