The infrastructure of the existing utility grid is dominated by outdated equipment to monitor and operate. The implementation of smart charging requires robust communication, controller, and fault tracking systems. A possible solution to meet robustness requires using data-rich monitoring systems to perform necessary forecasting and optimization. Another possibility is upgrading the utility grid by replacing current components with smart components. For example, the conventional transformer can be replaced by a smart transformer. Conventional monitoring systems in substations can be replaced with high-performance systems that can perform monitoring, forecasting, and real-time computation of necessary parameters for fault detection, prevention, and correction. Upgrading the utility grid adds a financial burden to the PSO. Further, renewables integration to the utility grid helps reduce capital expenditure spent on increasing generation [40-43], hence, the PSO prefers to add precision sensors, communication systems, and data storage devices to upgrade rather than replacing the components.

The possibilities of changing infrastructure are immense. Every addition or upgrade to implement smart charging will help make the utility grid infrastructure smart, thereby improving reliability and stability and helping the PSO perform necessary day ahead or month ahead planning to reduce losses, both power and financial.
