According to Mr. Nguyen Anh Dung, Deputy General Director of Hanoi Power Corporation (EVNHANOI), the utility currently manages 66 110/220kV substations with a total capacity of 9,503MVA. Recognizing the critical importance of the capital’s power system, EVNHANOI has been steadily advancing the application of scientific and technological innovations in its operations and management.

To meet the rising demands for quality and reliability in electricity supply, EVNHANOI has implemented distribution grid automation solutions, with equipment and substations connected and monitored through automated systems. This approach has simplified and improved system management and operations, while reducing incidents caused by human errors. Core technologies such as SCADA, DMS, DAS, and OMS serve as the backbone for real-time data collection from the grid, helping to shorten outage durations, minimize power losses, and reduce both maintenance time and costs.

“Equipment installed at substations transmits data on current, voltage, temperature, and anomalies every two minutes. If signs of discharge or overload are detected, the system immediately issues an alert to the control center, allowing early intervention and preventing widespread incidents. At the same time, the integration of digital platforms such as GIS (Geographic Information System), CMIS (Customer Management Information System), and PMIS (Power Management Information System) into a centralized management system has marked a major breakthrough in system operation, maintenance planning, and customer services,” Mr. Dũng explained.

At the customer level, EVNHANOI has already replaced all meters across the city with remote reading electronic meters. Customers now not only receive their monthly bills but can also track their electricity consumption on an hourly basis through the EVNHANOI mobile application.

Thus, the smart grid is no longer just about monitoring; it also offers intelligent analysis, forecasting, and early warnings, enabling the development of real-time optimized operational strategies.

Beyond early warning capabilities, the smart grid enhances load distribution, reduces local overloads, and facilitates the integration of renewable energy sources such as rooftop solar power.

The rollout of smart grid technologies also paves the way for Hanoi’s vision of becoming a smart city, where buildings, electric vehicles, and household appliances are interconnected and controlled according to real-time demand.
