A Romanian energy system model and a nuclear reduction strategy

This paper presents a model of the Romanian energy system with the purpose of providing a tool for the analysis of future sustainable energy strategies. The model represents the total national energy system and is detailed to the level of hourly demand and production in order to be able to analyse the consequences of adding fluctuating renewable energy sources to the system. The model has been implemented into the EnergyPLAN tool and has been validated in order to determine if it can be used as a reference model for other simulations. In EnergyPLAN, two different future strategy scenarios for the Romanian energy system are compared to the actual data of Romania of year 2008. First, a comparison is made between the 2008 model and the 2013 strategy scenario corresponding to the grid of the Romanian transmission system operator (TSO) Transelectrica. Then, a comparison is made to a second strategy scenario in which the installed nuclear capacity is reduced by 50%.

► This paper presents the model development of the Romanian energy system based on 2008 data.
► After testing and validation of the model, 2 future scenarios were simulated based on the obtained model.
► First simulation with the 2013 strategy scenario according to the Romanian TSO with increased renewable energy sources.
► Second simulation with a future strategy scenario in which the installed nuclear capacity is reduced by 50%.
