Abstract

The significant development of plug-in electric vehicle (PEV) is a challenge for distribution networks. The PEV charger is an electronic power device that generates large amounts of power over a period of time to charge EV battery. In addition, the EV on board charger (OBC) also produces harmonics due to the process of converting AC grid voltage to DC voltage. Converter as OBCs main device is a source of harmonics which directly connected to the distribution network. In this study, harmonics from single OBC, multiple OBC and PEV penetration scenario were evaluated and compared with the SPLN standard D5.004-1: 2012. From the study results, THD injected to the distribution network is influenced by the percentage of the base load and PEV penetration. The worst possible condition is occurred under low load conditions while high PEV penetration happens. From the simulation results using the distribution network model especially in residential area, the low base load scenario (10.47%) and the high PEV penetration (90.01%) is generating TDD 6.59% and THDv 2.61%. Therefore it is known that the harmonic effects generated by PEV charging to the distribution network still meet SPLN D5.004-1: 2012.
