  • Abstract The emergence of plug-in electric vehicles (PEVs) shall bring a significant impact on the existing power system. In this thesis, we propose decentralized energy management strategies for PEVs to mitigate the impact of PEV-charging by using the alternating direction method of multipliers (ADMM) base on smart grid. With the proposed strategies, we can handle the high penetration level of PEVs. However,
    the decentralized algorithm based on the ADMM method requires large numbers of iterations to achieve their optimal solutions. To improve their convergence rate, we divide the whole system into two sub-systems: the user sub-system and the grid sub-system. The user sub-system coordinates the PEV charging(discharging) and aims at maximizing user convenience levels while meeting predefined power demand
    limits. We develop a distributed algorithm to solve the charging(discharging) problem in a decentralized manner. In addition, we exploit driving habit of individual EV user to accelerate the convergence rate. On the other hand, the grid sub-system
    aims at minimizing power generation cost while meeting some circuit-level limits. We also develop a distributed algorithm to solve the optimization problem at the grid side. Finally, several simulations are conducted to verify the efficiency of the proposed energy management strategies.
