Abstract
Electric Vehicle is increase globally from day to day. The Malaysia government predicted that in years to come, the electric vehicle will play an important role in the daily life of Malaysia citizen. The charging stations however in Malaysia are in critical number. This can cause one place to be a hot spot for people to charge their electric vehicle. The additional electricity demand due to the high rates of electric vehicle charging at hot places is assumed will have an effect and also create many issues on the power system network. This project aims to analyze the impact of charging electric vehicle on Power System Network based on daily usage. The project looked at the voltage regulation limit and the transformer loading to determine the condition of the power system network. To accomplish the objectives, five main case studies were simulated with an additional mitigation simulation. Each simulation is developed and simulated using DIgSILENT-POWERFACTORY with the selected parameters. The software used is to emulate a 16-buses network with loads of houses, street lamp and charging stations. All the case study is simulated and been carefully analyze the outcome results. The outcome results are analyzed and compare with each other to meet all the requirement objectives. At the end of this project, all case study will be compared and indicates which case study with specific loads have a voltage violation. A mitigation simulation is to help to stabilized the voltage violation and the transformer loadings to the acceptable limit which the power system network can be operated. This project paper proof that with the additional electric vehicle charging stations, it will violate the voltage regulation limit and increase the transformer loadings.
