The Research and Innovation Center of Excellence “KIOS” of the University of Cyprus is coordinating a new research project, entitled “GridGnosis: Real Time Monitoring of Power Systems for Enhanced Stability”, which is funded by the Cyprus Research and Innovation Foundation through the Recovery and Resilience Facility. The objective of the project is to develop an integrated monitoring and protection system that will enhance the resilience, reliability and security of power systems.
The real-time and highly accurate monitoring of power system operating conditions, as well as of changing parameters such as transmission line characteristics and system inertia, plays an important role in ensuring the safety and reliability of power systems.
This information not only allows power system operators to be fully aware of the state of system operation, but also ensures the resilience and stability of the grid by allowing remote adjustments to protection systems.
In addition, timely information on the type and location of faults in the power system is of paramount importance for the rapid restoration of the network. Such monitoring and protection functions are becoming increasingly important in modern power systems, which are prone to large disturbances due to their operation close to their natural limits and the high penetration of Renewable Energy Sources (RES), which reduce system inertia.
GridGnosis Platform
To address the above challenges, the GridGnosis project will develop a platform that will incorporate innovative methodologies to accurately estimate (1) the system state, (2) the transmission line parameters and (3) the system inertia.
The platform will also include adaptive protection and management systems aimed at improving existing protection relays for ballast short-circuit clearance on transmission lines and early response to underfrequency phenomena. In addition, fault diagnosis methodologies will be implemented to automatically identify the point and type of short-circuit, allowing rapid restoration of the network.
All methodologies to be developed within GridGnosis will be based on measurements from phasor meters (PMUs) installed in the Cyprus transmission system. Coios will lead the development of methodologies and will play a critical role in their integration into the GridGnosis platform.
The results of GridGnosis will contribute to addressing the challenges faced by power system operators. The implementation of the GridGnosis platform in the electricity grid of Cyprus will enhance the stability of the system, allowing uninterrupted energy supply to end-users. In addition, the project solution will allow for a safer and more reliable penetration of higher RES penetration rates, reducing emissions, thus contributing to a better quality of life in Cyprus.
For the implementation of the project, the University of Cyprus’ KIOS Centre of Excellence will collaborate with the Cyprus Electricity Authority and the Cypriot SME H. Wise Wire Energy Solutions Ltd.
