RT21 | Real-Time Hardware-in-the-Loop (HIL) Simulation: Use Cases and Applications in TNB

This presentation will demonstrate the use of OPAL-RT in Hardware-in-the-Loop (HIL) simulation and its application in Tenaga Nasional Berhad (TNB). The TNB power systems are now increasingly complex, and coupled with large generating units connected on the grid and increasing renewable energy (RE) penetration in the capacity mix projected to reach 31% by 2025, grid operations become more challenging and system reliability might be jeopardized. As such, many real-time applications and protection and control systems, such as Wide-Area Monitoring, Protection and Control (WAMPAC), have been developed to enhance the security and reliability of TNB power systems. It has become a necessity to ensure that the reliability of the developed systems are not compromised. Therefore, HIL simulation has been identified as an effective approach to test and validate each newly developed system prior to the actual system deployment. The presentation will feature advancement made in real-time modelling and simulation of large-scale power systems in the phasor domain, and the integration of various components in the Power System Laboratory at TNB Research to meet the objectives and requirements of HIL.
