Resumen

Electric vehicle (EV) charging management can be im-plemented through centralized or decentralized strate-gies. Strategic coordination between these approaches enhances system efficiency and balances energy loads, thereby supporting the widespread adoption of EVs and fostering a sustainable, emissions-free society. In this study, distribution network operators (DNOs), acting as centralized charging managers, are respon-sible for mitigating the lack of coordination among electric vehicle aggregators (EVAs), which represent decentralized managers. The primary objective of the centralized management in this research is to con-strain each decentralized optimization model, char-acterized using Monte Carlo simulations. Three EV adoption scenarios–comprising 2,000, 2,500, and 3,750 vehicles–are evaluated by comparing decentralized charging management with an unregulated charging baseline in the IEEE 14-bus power system. Improve-ments are required only in the highest adoption sce-nario, where the proposed centralized coordination model is applied. The study models energy trading constraints for each EVA, assigning one aggregator per load-bearing bus in the system. Transmission-level results are analyzed and then synthesized for application in the IEEE 13-bus distribution power system. Findings demonstrate that coordinated centralized and decentralized charging management significantly improves operational conditions in both transmission and distribution networks without necessitating changes to travel behavior.
