碩士 === 國立臺灣科技大學 === 電機工程系 === 100 === Electric vehicle (EV) chargers are nonlinear power system loads, they will produce the harmonic and cause power quality problems. The purpose of this thesis is to discuss that the severity of background levels of the harmonic voltage, to assessment of how many chargers we can Install. First, studied the uncontrollable rectifier chargers, the way to reduce the harmonic of the uncontrollable rectifier chargers, and controllable rectifier charger`s mathematical and control method, and used the Matlab/Simulink to build the EV chargers, also used the Matlab to generate random parameters, and simulated the charging act of chargers. Next, base on the harmonic’s standard to consider the different scenarios to the simulation, discussion on different background levels of the harmonic voltage, and assessment of amount of the chargers in charging stations. Finally, according to the simulation show the results by statistical chart and cumulative probability distribution chart.In this thesis also compare with simulation and measured data, and they are very similar. Hence the outcomes of this thesis can provide a reference to planning charging station in the future.
