AGC Control introduced to enhance stability of national grid
Thursday, 7 May 2026
To maintain stability of the national power grid frequency, Secondary Control-AGC (Automatic Generation Control)-has been introduced alongside the previously implemented Primary Control-FGMO (Free Governor Mode of Operation) at power plants.
The AGC system has been implemented under the supervision of the National Load Dispatch Center (NLDC) of Power Grid Bangladesh PLC, with the support of the Bangladesh Power Development Board (BPDB) and the participation of power plants concerned, says a press release.
As a result, the stability of the grid frequency has significantly improved, which will facilitate the safe integration and operation of the Rooppur Nuclear Power Plant within the national grid.
To ensure grid frequency stability, Power Grid Bangladesh PLC has implemented a project titled "Bangladesh Power System Reliability and Efficiency Improvement Project." Under this project, the EMS software of NLDC has already been upgraded, and FGMO has been introduced in 30 power plants.
At present, 12 power plants have been incorporated under Secondary Control-AGC (Automatic Generation Control) to further stabilize grid frequency. It has been observed that simultaneous operation of both Primary and Secondary Control at power plants significantly enhances grid frequency stability. This operational activity was conducted on April 28 and 29.
