Abstract:
Electric vehicles integration in the distribution network are expected to increase the base and peak electric loads on the power system, increases technical losses, increases harmonic distortion and reduces the stability of the power system. Meanwhile, when used with bidirectional inverters as battery chargers, electric vehicles can work in V2G mode as EES and strengthen grid stability. This dissertation discusses how electric vehicles impacts voltage stability, power loss, harmonic distortion and system loading. In addition, the study proposes a design of electrical power supply for battery charging referring to the battery specifications available to the local markets. The model of battery chargers is developed in MATLAB software while distribution network test is conducted on a 34 buses taken from KINIGI feeder of CampBelge substation in northern corridor of nation grid by using ETAP software. The test came up with locating electric vehicles charging stations by taking into account the aforementioned factors, where 4, 1,2,2 and1 vehicles are located at 19, 20,23,25 and 26 respectively.
