A hybrid simulation model for large-scaled electricity generation systems

Due to the transition towards a sustainable energy supply, many electricity generation systems are faced with great challenges worldwide. Highly volatile renewable energy sources play an important role in the future electricity generation mix and should help compensate the phase-out of nuclear power in countries such as Germany. Simulation-based energy system analyses can support the conversion into a sustainable future energy system and are intended to find risks and miscalculations. In this paper we present models for the main components of the electricity generation system. We use a hybrid simulation approach with system dynamics and discrete event modules. This modular design allows quick model adoptions for different scenarios. Simulation results show the development of the future annual electricity balance, CO₂ emission balance, electricity imports and exports, and the wholesale price of electricity.
