This work package will address inter-substation communication solutions based on existing infrastructure technology and standards. In addition to this, it will explore the 5^th generation (5G) of mobile wireless networks, taking into account the requirements of state-of-the-art protocols such as IEC61850. Aligned with 5G, Ultra-Reliable and Low Latency Communications (URLLC) should be assessed as a possible solution for meeting the requirements of power system protection, which differ from other smartgrid technologies. In addition, 5G’s support of different networking slices and multi Radio Access Technologies (multi-RATs) will be studied as enablers of a better usage of infrastructures resources while simultaneously complementing the existing network solutions. In this WP topics of interest are:

• Latency and time synchronization, robustness and reliability, scalability and cost efficiency
• Service level agreement (SLA) monitoring and assurance
• Mitigation of communication loss
• Authentication and integrity (cyber security)
• Analysis of state-of-the-art protocols (e.g. IEC 61850, IEEE1588)
• 1 PhD
