Power system resilience is an overarching concept covering the whole spectrum of the power system, from design and investment decisions to planning, operations, maintenance and asset management functions. Flexibility concerns the power system's ability to manage changes, with flexibility features able to improve the resilience characteristics of the system, provided that they are integrated into grid planning, in defence plans, and evaluated adequately in the energy market design. An analysis of ongoing worldwide initiatives provides relevant insight into ongoing worldwide initiatives. They provide relevant insight into how flexibility can support resilience, showing the prominence and potential values that can be unlocked, with potentially some low-hanging fruits to start. This paper introduces four innovative concepts: Alternative grid development, system integrity protection schemes, the next level of flexibility and LINK holistic approach to flexibility for resilience as solutions contributing to improving future power systems' resilience.
This paper is the result of the work of a joint Task Force between ETIP SNET WG 1 (on Reliable, economic, and efficient energy system) and ISGAN Annex 6 on Power Transmission and Distribution Systems. The final report of the Task Force [9] provides the full details of this work presenting a global view on how flexibility can demonstrate value in improving the resilience of the power system.
