Abstract

Increasing awareness on environmental issues coupled with escalating prices of petroleum product has led to the development of greener electric vehicle in the last few decades. One of the most promising alternatives to reduce C02 emission and dependency on petroleum product in transportation market is the plug-in hybrid electric vehicle (PHEV). The battery of PHEV can be charged at home or other commercial locations through standard electrical power outlets. In Malaysia, the scenario of charging PHEVs at home is still new. The main objective of this project is to investigate the impact of introducing large amounts of charging activities in an existing residential area such as overloading of electrical network. undue stress due to inadequate line capacity and violation of voltage limits. The research used geographic information system (GIS) simulation software as a tool to investigate the impact of different penetration level of PHEV to the grid in selected residential networks in Malaysia This software is used to model the PHEV charging load to the distribution grid and charging scenarios as an imitation of the Malaysian driving style. The electrical network was created on the real map using Xpower software. The PHEV charging load modelling were created based on the daily load usage and the selected PHEV charging load rated at 3.8kW. Then, the charging scenarios and the respective simulation cases were created to represent the Malaysian driving behaviour and lifestyle focusing on the working days or weekday. The residential network randomly tested by the entire house having the PHEV charging load is called uncontrolled charging or a base case. The uncontroIJed charging strategy is obviously giving effect to the load demand on the transformer, voltage drop and power losses on the cable lines of the power system network. Hence, another strategy is planned to overcome this problem. By using controlled charging strategy and cable resizing strategy, the problem such increasing load demand, voltage drop and power losses of the lines are solved. Later, these simulation techniques of controlling charging strategy can be used as a guideline for the utility company.
