TCN deploys system to swiftly detect, respond to national grid collapse

The Transmission Company of Nigeria (TCN) says it has deployed a digital system called generation dip/loss detection system (GLDS) to swiftly detect and respond to sudden drops in power generation.

Ndidi Mbah, TCN’s spokesperson disclosed this in a statement on Wednesday.

The development comes at a time of recurring national grid collapse.

On April 15, the national electricity grid experienced a system collapse, leading to a nationwide blackout.

This was the third national grid collapse in 2024 after the grid, on February 4, collapsed for the first time this year, before the country suffered another nationwide blackout on March 28.

According to Mbah, to make efforts to enhance grid management, its engineers have recently deployed GLDS, which provides advanced tools for real-time monitoring and analysis of grid performance.

“This new innovation stands as a testament to the Transmission Company of Nigeria’s (TCN) commitment to advancing grid management capabilities,” TCN said.

“Designed to empower the National Control Center (NCC) in Osogbo, GLDS provides grid controllers in NCC with advanced tools for real-time monitoring and analysis of grid performance. Its intuitive interface allows for the setting of parameters, continuous monitoring of power generating stations, and comprehensive reporting functionalities, enabling swift responses to grid disturbances.

“GLDS incorporates sophisticated data analytics and machine learning algorithms to analyze real-time data and identify patterns associated with sudden generation loss. 

“By leveraging anomaly detection techniques, GLDS can promptly alert grid controllers on deviations from normal grid behaviour, facilitating proactive intervention to prevent widespread disruptions.

“Furthermore, TCN ensures seamless communication between GLDS and IoT cloud servers, enabling a more rapid response and coordination of mitigation strategies. 

“This connectivity underscores TCN’s commitment to enhancing grid resilience and ensuring the uninterrupted delivery of electricity to consumers across Nigeria.

“Previously, TCN engineers had developed an in-house design that leverages on loT technology as an innovative solution in response to the challenge of limited visibility of power generators. 

“The lot devices, which were strategically deployed across power stations and some substations, facilitate the collection of near real-time data, including power generation levels and grid performance metrics.

“The loT enabled the expansion of visibility of power generating stations from 6 to 27, this has helped TCN significantly improve its ability to monitor grid load and identify potential issues before they escalate.”

The spokesperson also said the GLDS represent a significant step in bolstering grid stability and reliability.

Mbah added that the initiatives not only empower TCN’s grid controllers with the insights needed to proactively address challenges and minimise disruptions but also demonstrate the company’s dedication to meeting the evolving demands of the Nigerian Electricity Supply Industry (NESI).
