HARMONIC DISTORATION IN ELECTRIC VECHILE - CHARGING STATION & MITIGATION TECHNIQUE USNIG AUHF - PASSIVE FILTER

Currently, the world is still heavily depend on conventional non-renewable energy, such as fossil fuels in producing the useful energy. From the world energy consumption statistics, 30% of the overall fossil fuel consumption was spent for transportation sector in 2012. Due to prospective shortage of fossil fuels as well as environmental issues on CO2emission, researchers and vehicle industries have started to focus on the electrical vehicle (EV) system, in order to find an alternative ways to overcome these issues [1-3]. Based on the statistic portal, there are around 200,000 EVs use globally in 2013. In the early 2016, the number of EV has increases to 1.3 million units, and China aims to increase the stock of EV to about 11.9 million units by 2020. There are many advantages of EV compared to traditional combustion vehicle such as environmental friendly, more efficient motor, and require less cost of maintenance.

The increasing number of EV has led to increase in number of charging station (CS). The function of CS is to transfer electric power from an electric source to EV outlets through communication equipment for a safe flow [4]. However, the integration of CS gives negative impact to the distribution system such as power loss increased and violation in voltage profile [4-9]. This is due to the harmonic produced from nonlinear load of EV during charging process at CS. From this effect the passive is design from a desired tunning and the THD I , THD V are get to normalize according to IEEE-519. Let the matlab simulation of EV-CS .

We develop a wonderful passive design for mitigation harmonics from CS . And Research are going on further development of filter and the distoration limit to lower to <5%.
