NDO - Power Transmission Company 3 manages and operates the power grid in 9 provinces of the South Central Coast and Central Highlands. In recent times, the company has had solutions to improve its capacity to manage, regulate and operate the power transmission grid, especially renewable energy sources that are playing an increasingly important role in the national power system.
On February 21, in Da Lat city, Lam Dong province, Power Transmission Company 3 (PTC3), under the National Power Transmission Corporation, organized a workshop on "Coordination of dispatching, management and operation of the transmission grid".
The workshop was attended by representatives of the National Power Transmission Corporation; Departments of Industry and Trade of Gia Lai, Dak Lak, Dak Nong, Lam Dong, Binh Dinh, Khanh Hoa, Ninh Thuan, Binh Thuan provinces; 98 factories, renewable energy companies and hydropower plants in the South Central Coast - Central Highlands provinces.

PTC3 is managing and operating the power transmission grid in 9 provinces of the South Central Coast - Central Highlands, including: Khanh Hoa, Phu Yen, Binh Dinh, Gia Lai, Dak Lak, Ninh Thuan, Dak Nong, Lam Dong, Binh Thuan, with 2,338km of 500kV lines, 3,670km of 220kV lines, and 27 transformer stations; transformer capacity has a capacity of more than 17.2 thousand MVA.
Speaking at the workshop, PTC3 Director Nguyen Cong Thang said that the workshop was an opportunity to analyze the current situation, difficulties and share experiences, finding optimal solutions to ensure that the power transmission system always operates safely, continuously, effectively and stably for economic, political, social, security, defense activities and a stronger Vietnamese electricity market in the new era.
The Director of PTC3 said that the company has had important orientations to improve the capacity of management, dispatch and operation of the transmission grid, especially in the context of renewable energy sources playing an increasingly important role in the national power system. At the same time, it aims for sustainable growth, strong development and far-reaching in the era of the Vietnamese nation's rise, the era of international integration and green, sustainable energy conversion.

Delegates attending the workshop. |
There are currently 98 power plants connected to the grid managed and operated by PTC3; including many types, such as: wind power (27 plants), solar power (21), hydropower (24), biomass (2) and thermal power (4), with a total capacity of nearly 17 thousand MVA. Of these, only 14 plants belong to EVN, the rest belong to investors outside of EVN.
According to the assessment, many factories have diverse connection forms such as transition connection to the transmission grid, to the transformer station busbar, or connection to the 110kV grid of other power companies. This creates great challenges in ensuring stable grid operation, and at the same time requires close coordination between management units and external investors to maintain the safety and efficiency of power transmission.

Ensuring management and operation at the 500kV Di Linh transformer station, Lam Dong province. |
At the workshop, delegates discussed and clarified issues that are prone to power grid failures, the risk of damage to some transformer station equipment, as well as the quality of newly energized equipment; arising issues that need to be coordinated to resolve...
Many opinions say that it is necessary to have an advanced operating force with the ability to react quickly and a reliable monitoring system to be able to quickly detect and handle potential incidents, thereby minimizing the risk of affecting the transmission grid.

In the coming time, PTC3 will focus on enhancing coordination between dispatching and operating units and power plants to ensure synchronous system operation, minimize incidents and optimize generation capacity; strongly apply digital technology, artificial intelligence and automation in monitoring, operating and coordinating the grid to improve efficiency and forecasting ability.
At the same time, promote cooperation with state management agencies, local authorities and enterprises to remove difficulties in mechanisms and policies, especially the issue of transmitting electricity from renewable energy sources to the national power system.
