Smart cities require the development of information and communication technology to become a reality (ICT). A “smart city” is built on top grid”. The implementation numerous smart systems that are advantageous environment improve quality life for residents one main goals new cities. In order reliability sustainability transportation system, changes being made way electric vehicles (EVs) used. As EV use has increased, several problems have arisen, including requirement build charging infrastructure, forecast peak loads. Management must consider how challenging situation is. There been many original solutions these problems. These heavily rely automata models, machine learning, Internet Things. Over time, there more drivers. Electric vehicle at large scale negatively impacts power grid. Transformers may face additional voltage fluctuations, loss, heat if already operating full capacity. Without management, challenges cannot be solved. machine-learning (ML)-based charge management system considers conventional charging, rapid vehicle-to-grid (V2G) technologies while guiding cars stations. This operation reduces expenses associated with high voltages, load fluctuation, loss. effectiveness various learning (ML) approaches evaluated compared. techniques include Deep Neural Networks (DNN), K-Nearest Neighbors (KNN), Long Short-Term Memory (LSTM), Random Forest (RF), Support Vector Machine (SVM), Decision Tree (DT) (DNN). According results, LSTM might used give control in certain circumstances. model’s voltage, losses, stability all improved by compressing curve. addition, we keep our billing costs minimum, as well.
