90021 - Control Co-Design Optimization of Natural Gas Power Plants With Carbon Capture and Thermal Storage 

In this work, an optimization model was constructed to help address important design and operation questions for a novel system combining natural gas power plants with carbon capture and thermal storage, which is expected to play a significant role in future, close to carbon-neutral energy markets. A control co-design (CCD) approach is taken where key plant sizing decisions (including storage capacities and charging efficiency ratios) and operational control (e.g., when to store and use thermal energy and operate the plant) are considered in an integrated manner using a nested CCD strategy. The inner-loop, control-focused optimization problem is a large, sparse linear program that determines optimal operations for an entire year (either all-at-once or through a moving prediction horizons strategy) given fixed plant design variables. On the other hand, the outer-loop optimization problem is formulated as a constrained non-linear optimization program aimed at maximizing the system's net present value over its entire lifetime by determining the plant design variables' optimal value. The results generated using this model demonstrate both the need for optimal operation to enable a fair economic assessment of the proposed system as well as optimal sizing decisions due to sensitivity to a variety of scenarios, including different market conditions, site locations, and technology options.
