“…This study centered around investigating a control strategy for an IES operating in energy arbitrage mode [29]. The IES, shown in block diagram form in Figure 55, contained a tightly integrated CTES system charged by a NuScale-style LWR, and generated excess electricity by incorporating produced steam into the main steam turbine train.…”

This publication details newly created energy storage and reactor models developed within the HYBRID modeling repository as part of the Department of Energy (DOE) Office of Nuclear Energy Integrated Energy Systems (IES) program, led by Idaho National Laboratory (INL).The model development included creating dynamic systems-level models of a pebble-bed high-temperature gas-cooled reactor (HTGR), a sodium fast reactor (SFR), compressed air energy storage (CAES), liquid air energy storage (LAES) and Modelica standard library (MSL)-based two-tank sensible heat storage (SHS) in the IES-based HYBRID repository. These models were developed using the latest publicly available data and incorporating the possibility of control strategy inclusion for use with the existing IES modeling, analysis, and optimization toolset. Simulations showcase the capability of each technology to flexibly operate in ways consistent with IES operation expectations.When these models are available, they can be utilized within different integrated energy park concepts to understand optimal system operation, control, and dispatching. Moreover, given the generic nature of the models, industrial partner technologies can be quickly added to the repository by using the existing models as a basis. Additional dynamic models for thermal energy storage (TES) concepts can be developed and added to the HYBRID repository as needed. Also detailed in this report are future development goals for the HYBRID repository, including adding suites of steady-state models, economic costing information, and reduced-order models (ROMs).

“…Recently, Mikkelson et al 9 concluded that a control system can be established allowing near-constant operation of a nuclear reactor core at full power while following variable electrical load using a concrete TES. Their model allowed for electrical energy outputs between 70-120% of nominal power.…”

The increasing installment of solar and wind renewable energy systems create a volatile energy demand to be met by electricity providers. A nuclear hybrid energy system is a nuclear reactor with energy storage that integrates into the grid with renewable energy sources. The Natrium design by TerraPower and GE Hitachi is a sodium fast reactor with molten salt energy storage. The Natrium design operates at steady state of 345 MW and can boost up to 500 MW for 5.5 hours. This study uses Dymola and the Modelica language to model the Natrium-based NHES. The dynamic system model is tested using hourly historical data form Texas (ERCOT) 2021 to show how renewables affect the electricity demand and how energy storage affects the Natrium system response to the demand. According to the results, while the available storage will allow the Natrium design to boost electricity production when the demand and electricity price is high making it more economically viable, the current molten salt storage is undersized for the ERCOT market.

The increasing installment of solar and wind renewable energy systems create a volatile energy demand to be met by electricity providers. A nuclear hybrid energy system is a nuclear reactor with energy storage that integrates into the grid with renewable energy sources. The Natrium design by TerraPower and GE Hitachi is a sodium fast reactor with molten salt energy storage.

This study uses Dymola and the Modelica language to model the Natrium‐based nuclear‐renewable hybrid energy system. The dynamic system model is tested using hourly historical data from the state of Texas 2021 to show how renewables affect the electricity demand and how energy storage affects the Natrium system response to the demand. According to the results, while the available storage will allow the Natrium design to boost electricity production when the demand and electricity price is high making it more economically viable, the current molten salt storage is slightly undersized for the ERCOT market.
