Impacts assessment of PHEV charge profiles on generation expansion using national energy modeling system

High penetration of plug-in hybrid electric vehicles (PHEVs) in the next 5-10 years is plausible due to the benefits for both environments and end users. With the assumption of a high PHEV penetration, national energy modeling system (NEMS) software package is exploited to predict the growths of power generation plants. As an adjustable knob for the deregulated electricity market, the charging strategy of PHEVs is comparatively studied to gain a comprehensive picture of its impacts. Four typical daily charging strategies are investigated, which are: (1) uniform charging; (2) home-based charging; (3) off-peak charging; (4) vehicle-to-grid (V2G) charging. Electric capacity expansions by fuel types and preferred PHEV load profiles are characterized.
