Optimal Security Constrained Economic Dispatch in Nuclear Integrated Energy Systems

As global energy systems evolve to address rising demand, emission reduction targets, and the integration of diverse energy sources, innovative approaches to system optimization become essential. This paper focuses on a novel nuclear integrated energy system configuration that combines small modular reactors, renewable energy sources, energy storage, and a thermal network coupled with the IEEE-30 Bus system for security constrained economic dispatch. By integrating nuclear baseload generation with intermittent RES, the approach enhances operational flexibility and efficiency in complex, multi-input, multi-output energy configurations. A non-linear programming model is developed to address the security constrained economic dispatch and the intricate interactions between electrical and thermal subsystems, while ensuring alignment with operational and transmission constraints. The findings of this study demonstrate that such hybrid systems can effectively meet diverse energy demands and support decarbonization goals through profitable energy dispatch strategies.
