The surge in adoption of renewable vitality pushed by carbon neutrality insurance policies has created operational challenges for giant thermal energy crops. These crops should now accommodate speedy load fluctuations and provide versatile operation, which entails adjusting their outputs quickly because the renewable mills’ outputs fluctuate. Nevertheless, working past unique design specs locations further stress on energy crops, reduces effectivity, and will increase the danger of failure.
Challenges of Versatile Operation in Thermal Energy Vegetation
Thermal energy crops designed for baseload operation face essential challenges with versatile operation, together with:
- Stress and Put on. Frequent startups and cargo modifications result in boiler instability, thermal fatigue, corrosion, and turbine degradation.
- Upkeep Dangers. Prolonged startup/shutdown cycles improve erosion, water hammer impact, and valve injury.
- Higher Want for Preservation. Extended downtime raises the danger of turbine corrosion and requires higher preservation strategies for condensate, feedwater, and cooling methods.
These challenges name for modern options to maintain the ability mills dependable and environment friendly underneath dynamic grid circumstances.
Digital Transformation: A Necessity for Energy Vegetation
Right this moment’s trade traits are dominated by digitization, massive knowledge, synthetic intelligence (AI), cloud computing, mobility, and platform applied sciences. Conventional strategies for managing energy belongings have reached their limits in addressing the challenges raised by carbon neutrality. Digital transformation for energy crops requires processing the huge time-series knowledge from tens of 1000’s of on-site sensors into massive knowledge. Actual-time evaluation is essential for detecting anomalies early, stopping gear failures, and enabling sensible, data-driven decision-making.
Introduction of the IDPP Platform. The Clever Digital Energy Plant Platform (known as IDPP, IDPP Platform, or the Platform) is an AI-driven system that collects, standardizes, shops, and makes use of huge time-series sensor knowledge from essential gear comparable to boilers, generators, and mills. It makes this knowledge available to satisfy the varied wants of plant operators.
Developed over 5 years by Korea Electrical Energy Company (KEPCO) at its Analysis Institute (KEPRI), IDPP addresses the urgent challenges of effectivity maximization, reliability enhancement, value discount, and fault prevention in massive energy crops intensified by an elevated want for versatile operation. The IDPP integrates Web of Issues (IoT) sensor knowledge and applies AI algorithms, and the operators can create their very own functions (Apps) that entry the Platform’s knowledge to hold out duties comparable to situation monitoring, fault prediction, and efficiency analysis.
Key Capabilities and Positions of the IDPP. In contrast to conventional methods that relied on relatively outdated, developer-centric knowledge assortment and evaluation strategies, the IDPP (Determine 1) is user-oriented and engages up-to-date applied sciences. The IDPP Platform collects large-scale operational knowledge in real-time, and makes use of AI and algorithm-based evaluation to detect early indicators of abnormalities, enabling predictive upkeep. Sensor knowledge from plant gear is first gathered by means of the distributed management system (DCS), transmitted to a real-time database (RTDB) server, and saved in parallel utilizing open-source applied sciences comparable to Kafka, Druid, and Hadoop.

Up to now, greater than 30 Apps have been developed utilizing the IDPP Platform, with extra underneath steady improvement. Current Apps embody:
These Apps spotlight the IDPP’s superior capabilities in bettering operational reliability and effectivity in energy plant administration. |
Confirmed Observe Data
By 2023, IDPP had been carried out throughout 19 thermal energy crops operated by KEPCO’s 5 technology subsidiaries (GENCOs), protecting a mixed capability of seven.5 GW. The Platform collects a powerful 7.3 trillion knowledge factors yearly at sub-second intervals from roughly 230,000 on-site sensor tags. Just lately, IDPP expanded its protection to a further 9 models in Korea, bringing the entire capability to about 17 GW.
The GENCOs are having fun with a major profit by implementing the IDPP, together with optimization of vitality manufacturing and substantial value discount, reinforcing KEPCO’s dedication to innovation and operational excellence.
Worldwide Recognition
KEPCO’s IDPP Platform was featured in a white paper titled “Virtualizing Energy Methods: How Digital Twins Will Revolutionize the Power Sector” that was revealed in October 2024 by the Worldwide Electrotechnical Fee (IEC), a worldwide requirements group that develops and promotes worldwide requirements for electrical, digital, and associated applied sciences. The IEC launched the next key options of IDPP, emphasizing KEPCO’s success in bettering the accuracy of sensor knowledge and enhancing operational effectivity in energy crops:
- AI-friendly, real-time sensor knowledge administration platforms.
- Siren-X, an early warning system.
- AI-based standing prognosis.
- IoT-based prognosis.
- Asset efficiency administration.
These developments display KEPCO’s management in integrating cutting-edge applied sciences to optimize energy technology operations.
Increasing Horizons
KEPCO goals to develop IDPP’s utility throughout all energy belongings in Korea to optimize energy plant operations and obtain carbon neutrality. Whereas at present centered on thermal energy crops, the Platform’s capabilities maintain potential for different energy provide gear producing massive operational datasets. For example, knowledge facilities the place energy outages can result in substantial losses require real-time, correct monitoring and prevention of energy provide gear failures.
On the worldwide stage, KEPCO is actively pursuing alternatives in abroad markets. Discussions are ongoing with utilities that search smarter asset administration options to boost gear reliability and cut back prices. These efforts are setting the stage for the IDPP to achieve traction worldwide, reinforcing KEPCO’s place as a pacesetter in modern vitality options.
