This paper analyses the impact that the introduction of Plug-In Hybrid Electric Vehicles (PHEVs) with different charging strategies have on the operation of power systems with high penetration of renewable generation. For this purpose, a medium-term electricity production model was used in order to perform a detailed analysis of the power system operation when: 1) PHEVs are dumbly charged; 2) PHEVs are smartly charged; and, 3) PHEVs are smartly charged and have vehicle-to-grid (V2G) capability. A reference scenario without PHEVs was also considered for comparison purposes. Results for the three charging strategies demonstrated that smartly charged vehicles improves system operation by flattening the demand curve and reducing operational reserves requirements, especially when V2G strategy is adopted. As a consequence of this, total and average system operation costs are reduced.
