Dynamic Modeling and Simulation of Integrated Energy Systems with Nuclear, Renewable, and District HeatinG

There is a paradigm shift in the energy industry towards green technologies which have incentivized nuclear and renewable-based energy production. The thermal power from the nuclear process could be optimally utilized to generate various end products thereby increasing the efficiency of nuclear power plants. A power plant being used for both electricity and heat is called an integrated energy system. One such integrated energy system coupling nuclear and wind energy resources by supplying electricity to the power grid and heat energy to a district heating network, is modeled and simulated in this paper. The dynamic model of the integrated energy system is developed using the Modelica language. Coordinated control is designed to ensure that the actual generation follows the demand associated with different end products. The performance of the dynamic model is evaluated for steady state responses and load following capabilities.
