Book excerpt: "Proliferation of plug-in electric vehicles (PEVs) with poor regulation might impose additional stress on distribution grids and cause severe local grid problems. To alleviate potential negative impacts due to PEV loadings and to avoid costs from installing new generation capacity and postponing network reinforcements, coordinated schemes need to be applied. This thesis focuses on a multidisciplinary study on smart management of PEVs with the aid of advanced information and communication technologies (ICTs). A co-simulation environment is developed in collaboration with the Optical Zeitgeist Laboratory. A coordination scheme is then proposed, with the goals of achieving peak shaving and valley filling and maximum utilization of local renewable energy sources without compromising on vehicle owners' driving needs. The scheme is optimized in terms of different objectives with respect to either charging or discharging periods and multiple charging locations. The study is based on real-world transportation data and a residential network model mapped with a fiber-wireless communications infrastructure. By performing co-simulation, the proposed scheme is examined from the aspect of power engineering, including power demand, losses, and nodal voltage magnitudes obtained from load flow analysis, and simultaneously from the communications perspective such as required channel bandwidth and delay. The scheme is tested in comparison to a benchmark coordinated charging scheme, and its efficacy is also verified in a sensitivity analysis with a higher PEV penetration level." --
