研究目的
To analyze the effects of harmonic distortion caused by photovoltaic systems and electric vehicle chargers on low voltage residential distribution systems, considering daily profiles of residential loads, PV generation, and EV chargers with characteristic harmonic spectra.
研究成果
The integration of PV and EV on a low voltage distribution system affects THDv daily profile, with harmonics flow highly dependent on the phase angle. For the simulated penetration levels, THDv remains below standard limits, indicating no immediate problem of harmonics. However, scenarios with higher levels of loads and more variety of nonlinear loads need further evaluation.
研究不足
The study is limited to specific scenarios of low and high penetration levels of PV and EV, and does not explore higher levels of loads or more variety of nonlinear loads. Analysis of triplen harmonics flowing through neutral is under study for further work.
