Query: Can models for long-term decarbonization policies guarantee security of
  power supply? A perspective from gas and power sector coupling   The assessment of adequacy and security of the energy system requires the
detailed knowledge of physical and operational characteristics. In contrast,
studies concerning energy transitions employ stylized models that oftentimes
ignore the technical properties but have a lasting influence on long-term
energy policies. This paper investigates the gap between energy system planning
and operational models by linking these two perspectives: (1) a long-term
investment model with low spatial resolution and high level of aggregation, and
(2) a spatially resolved system security model that captures the
interdependences between the backbone of the electric power sector, i.e., the
electricity and the gas infrastructures. We assess EU decarbonization pathways
of the electricity sector towards 2050 by integrating the investment decisions
of the long-term planning model and the safety performance of the resulting
system operations via the security assessment model. In a large RES deployment
scenario, we investigate two flexibility options: gas power plants and
cross-country transmission expansion. Using the integrated model, we analyze
how the adequacy and security of supply under extreme short-term operational
conditions impact the long-term planning of the energy system and the
investment decision-making. We provide country specific recommendations for UK.
Results indicate weaknesses in the gas-electricity system and suggest
improvements on capacity allocation.
