ABSTRACT Despite all the efforts made so far, reaching ambitious NetZero targets in electricity grids seems far-fetched due to stability-related challenges brought about by limitations, volatility and intermittency of renewables. The behaviour of invertor-based resources (IBRs) in response to system disturbances is fundamentally different than that of synchronous generating units. Recent examples and expected trends demonstrate that the operation of system integrity protection schemes (SIPS) will be adversely affected by the increasing integration of renewables into power systems. This is why it is essential to understand the nature of IBR’s impact and its consequences. The MIGRATE (Massive InteGRATion of power Electronic devices) project was a Horizon-2020 EU-funded research project, carried out by a consortium of 24 partners (eleven TSOs, twelve universities/ labs and one manufacturer) aimed at finding solutions to technological challenges brought about by renewables. Work package 4 of MIGRATE focused on “Protection schemes in transmission networks with high penetration of IBRs”. The main aim of the work package was to investigate the performance of existing SIPSs that are deemed more vulnerable to high penetrations of renewables. Based on responses from MIGRATE TSO partners, three SIPSs were identified as important and chosen for further scrutiny by the work package. These protection schemes were: • Under frequency load shedding (UFLS) • Under voltage load shedding (UVLS) • Power swing tripping (PST) In this special session, we will show that holding onto legacy SIPSs can greatly contribute to falling behind NetZero solutions. The panellists will present the main project results in terms of challenges, opportunities and future of SIPSs as well as a series of SIPSs solutions proposed in the Project. Conclusions drawn from our research will be presented to share our views on how best we can upgrade existing SIPSs in order to reduce the risk of catastrophic blackouts and push toward future low-carbon networks
