| dc.description.abstract | As cheap and affordable variable Renewable Energy Sources (vRES), such as wind farms and photovoltaics, are foreseen to dominate the future energy mix, the abundance of green electricity will allow the replacement of fossil fuels in sectors such as heating, cooling, industrial processes, and transport.
The intermittency and/or low controllability of vRES implies the significant systemic needs of flexible solutions; therefore, the developments of the energy system in general, and the power sector in particular, have led to significant innovation activities in the fields of power system flexibility. At the same time, the complexity and interdependencies of system components and multitude of actors increase the risks of service failures, thus raising needs of stronger and more flexible resilience means and countermeasures.
Power system resilience reflects the impact of severe and/or unpredictable events and 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 systems ability to manage changes; the future wide portfolio of flexibility means and their features can also improve the resilience characteristics of the broader view system of systems, provided that they are integrated in grid planning, grid operation, defence plans, and properly evaluated in the energy market design.
In this paper we are discussing on “How can flexibility also support resilience?”, considering the increased societal needs of a secure electricity supply. | en_US |
