Abstract

Commonly used interfacing technique of DC renewable energy sources like photovoltaic (PV) solar generators with the high voltage (HV) distribution line employs inverter that increases cost and creates PQ (power quality) problems. A standalone PV generator also needs battery support for energy storage. The proposed scheme in this paper utilizes two zigzag transformers to interface any DC power source with a HV AC distribution line fed from a delta connected 3-phase supply. AC-DC power simultaneously flows through the line. Existing substation batteries are used as energy storage device and no inverters are required.
