The state-owned Power Grid Company of Bangladesh (PGCB) is going to modernise its National Load Dispatch Center (NLDC), which will help enhancing efficiency of transmission of 60,000MW of electricity by 2041, official said. To this end, the government has taken various types of initiatives. Out of these, ‘free governing mode of operation’-FGMO will be introduced in power transmission line to protect national grid. Initially 10 power plants will come under the modern technology, officials said.
Bangladesh Power Development Board (BPDB) and PGCB will implement the new system within 6 months. PGCB was established under National Load Dispatch Center (NLDC) for a centralized coordination among generation, transmission and distribution of the existing power system. The other objects are operating each power station and substation at an economically profitable unit, reduce operational loss to save the electrical motors from being burnt-out due to excessive variation in voltage and frequency and to improve communication between all the electrical installations in the existing power system through modern SCADA techniques & Communication network.
A power division official said that the transmission system will undergo radical changes with the implementation of the FGMO. It will help to control power transmission system.A PGCB official said that currently many functions of the power transmission systems are working manually. After implementation of FGMO, the whole process will run automatically. The FGMO will have a fixed frequency of power transmission, which would be 49 HZ to 50.5 HZ.
The NLDC will set a daily demand of electricity and the power will be generate according to the demand. There will be an automated review of this demand and generation every 15 minutes. This method can prevent unwanted accidents. As a result, there will no chance to shut down all power plants, like power outages or blackouts across the country.
Earlier on November 2014, a blackout occurred in the country. The electricity was disconnected for more than 24 hours all over the country. Then the government took various initiatives to protect the national grid. However, FGMO is the most advanced method, through which the power plants can be controlled centrally.
However, the government is concerned over power transmission to the grid as the demand and supply gap widens during peak and off-peak season. The difference between peak and off-peak season is around 6,000MW to 7,000MW. The gap is likely to be more widened as the mega power plants like Rooppur Nuclear Power Plant in Pabna will be commissioned in the next two to three years.
It will create a major problem to the state-owned Power Grid Company of Bangladesh (PGCB) to make a stable supply of power to the grid, official said. A reliable and modern distribution system will help power transmission system, they said, adding that proper integration measures for renewable will also help grid stability.
