An extended abstract entitled ‘Wide Area Monitoring and Advisory Service for Smart Grids as a 5G-enabled Network Application’ was presented by Smart5Grid partners Daniel Shangov from ESO EAD and PhD Research Associate Irina Ciornei from the University of Cyprus KIOS Research Center of Excellence on June 27th, 2023 at the 31st Mediterranean Conference on Control and Automation (MED2023) – Limassol, Cyprus held between June 26th and 29th, 2023 (MED2023). This work elaborates on the use of 5th generation wireless communication as key technology for enabling secure, scalable, and flexible digital services for electric power and energy stakeholders. Specifically, it introduces the Network Application concept defined by the Smart5Grid Project for rolling out such type of smart grid digital services. A concrete example in terms of development, implementation and testing of Wide Area Monitoring services as a 5G-enabled Network Application in a Hardware-In-the Loop (HIL) testbed is also provided. The integration and testing results discussed in this extended abstract demonstrate the viability of the proposed solution. The extended abstract is included in the MED2023 Proceedings. https://med2023.eu/
