Sustainable charging station allocation in the distribution system for electric vehicles considering technical, economic, and societal factors

With a greater emphasis on achieving sustainable objectives, attention has switched to the electrification of the transportation sector. In the modern transportation industry, the burgeoning number of electric vehicles is progressively leading to the phase-out of petroleum-based cars. The quick deployment of electric vehicles, on the other hand, is heavily reliant on the coordinated and rapid construction of an electric vehicle charging ecosystem. The fusion of the electric vehicle charging ecosystem in today's distribution network with penetration of randomly dispersed photovoltaic systems is intricate since it might result in high power losses and voltage variances above permissible limits. This study employs the Grey Wolf Optimization to organize the charging ecosystem in the grid in order to maximize the profits while remaining within the legal bounds of limitations and maintaining user comfort in mind. The study incorporates the human inconvenience factor to provide the better results. The whole research is carried out using an IEEE 33 bus test system, which replicates a balanced radial distribution network for the deployment of electric vehicle charging ecosystems. It has been discovered that strong buses in the system can endure the installation of fast-charging ecosystem up to a certain point. In contrast, deployment of charging ecosystem on weak buses obstructs the functioning of the power system with increased losses, penalties and frequent blackouts.

Automated summary

With a focus on sustainability, attention has shifted to the electrification of the transportation sector. The increasing number of electric vehicles is leading to the phasing out of petroleum-based cars. However, the rapid deployment of electric vehicles relies on the construction of a coordinated charging infrastructure. This study uses Grey Wolf Optimization to organize the charging ecosystem in the grid, maximizing profits while meeting legal bounds and user comfort. It is found that strong buses can handle the installation of fast-charging infrastructure, while weak buses obstruct the power system.
