    This study aims to build a method for validating a power system model in the PLEXOS software. Special emphasis is put on the carbon dioxide emissions modelling. A case study of Germany and Poland is formulated in order to apply the created procedure to a European power model. The verification of emissions being one of the outputs, is divided into two phases. The first one focuses on the historical results from 2016-2017, which are compared with the chosen reference statistics and the emissions results obtained in another optimization tool. The second phase looks into the trends of emissions in the near future, i.e. time period between 2019-2025. OSeMOSYS as the second piece of software is used for benchmarking the results obtained by the PLEXOS model.

    Energy security is one of the critical priorities of energy policy in the European Union and particularly in the Baltic region that is currently transforming itself from an isolated energy island to a highly interconnected area. In this paper, a comprehensive analysis of energy security in Estonia, Finland, Latvia, and Lithuania in the context of the energy transition is presented. The paper explores regional implications of two paths of carbon price (gradual and delayed carbon price increase). The analysis is performed by linking an energy system optimisation model with a probabilistic model of energy security. This modelling suite is used to assess the resilience of the planned energy system to possible disruptions. The results demonstrate that carbon price paths have a modest impact on energy security in Baltic countries if energy security measures are implemented in an optimal way. The research is based on the case study conducted in the framework of the European Union's Horizon 2020 project REEEM.
