The forum is jointly organized by Georgian State Electrosystem and Lean Power Solutions with the support of PSCAD and RTDS Technologies and is scheduled to take place in Tbilisi, Georgia, on September 9 – 10, 2025.
This event will bring together transmission system operators from the Black Sea region, along with technical experts, system planners, and decision-makers, to address current challenges and solutions of power system operation. The forum serves as a platform to strengthen regional
cooperation by fostering dialogue, sharing technical expertise, and addressing common operational challenges, the event aims to enhance cross-border collaboration and support the development of a more secure, stable, and interconnected regional power system.
The focus will be on electromagnetic transient (EMT) studies using PSCAD and real-time digital simulation with RTDS. Participants will learn about tools and methodologies that improve system reliability, dynamic stability, and operational readiness in today’s complex power grids. As the integration of renewable energy sources, like wind and solar, accelerates, traditional modelling approaches often fall short in capturing rapid phenomena associated with inverter-based resources, HVDC systems, and FACTS devices. EMT tools are vital for ensuring grid stability, enabling detailed analysis of protection systems, transient behaviour, and control interactions that cannot be observed in phasor-domain (RMS) simulations.
EMT analysis is essential for preventing blackouts by examining rapid, nonlinear events like protection malfunctions and control instabilities and interactions between converters that may lead to cascading failures. It allows TSOs to validate system behaviour under stress, identify vulnerabilities, and implement mitigation strategies. Additionally, EMT analysis encompasses transient events such as lightning strikes, switching operations, and fault-induced overvoltages, making it essential for validating modern power system performance.
RTDS is a vital tool for high-fidelity, real-time simulations across various operational, planning, and testing scenarios. Unlike offline simulation tools, RTDS allows TSOs to simulate complex scenarios in real-time, facilitating the integration and testing of physical hardware through hardware-in-the-loop setups. This feature is particularly beneficial for validating protection and control schemes under realistic conditions, minimizing risks associated with field testing. Key applications of RTDS include testing relays, communication-based protection systems, and control devices like those in HVDC links and grid-following or grid-forming inverters.
