Description
Summary:There is a need to provide multiple Electric Vehicle (EV) charging locations while keeping the grid demand balanced, as with many EVs plugging in to charge at once, there can be a strain on the power grid with the surge in demand response, resulting in overloading of the grid, reduced reserve margins, power instability and finally, reliability issues. There are many options available to help reduce the impact on the grid such as Energy Storage Systems (ESS), Lamppost Charging, Vehicle to Grid (V2G), Smart Charging, Solar Photovoltaic (PV) and Improving Transport Facilities. While it is essential to maintain grid integrity, there is also a need to have good social benefits for EV users, where there is no compromise to how users utilise the system. Research the advantages and disadvantages of many of the strategies that are out in the market and discuss which is the most feasible for deployment in Singapore’s context must be done. To do this, there must be logical and technical details as to why the strategies may or may not be suitable in Singapore, factors such as space constraints, safety, environmental, social, and building infrastructure of a densely populated country must be taken into consideration. This paper explores different charging strategies and methodologies to help ease the burden of mass EV charging on the power grid as well as to maximise profits and social benefits for both EV owners and network providers.
