Visualizing the Impact of PEV Charging on the Power Grid

The penetration level of Plug-in Electric Vehicles (PEVs) is projected to rise in the future, which will lead to significant stress to the power grid due to frequent charging behaviors and their high power demand. While many studies have demonstrated the static stress caused by PEVs for specific scenarios, there is no software platform available for the visualization of the PEVs’ dynamic impacts at the distribution level of the power grid. This paper presents a software prototype that fills this gap. The prototype allows for easy parameter definition, including driving habits, and PEV types. Its back end allows fast integration and data processing for scattered PEV charging over wide areas. The prototype also considers mitigation efforts by providing built-in algorithms for coordinated charging and location planning of charging stations. The prototype is demonstrated on the IEEE 8500 node test case and power systems within Columbus, OH ranging from 81 to 1230 nodes.
