Short-term modeling of hybrid geothermal systems for Model Predictive Control

Iago Cupeiro Figueroa, +2 more
- 15 May 2020 - 
TL;DR: In this paper, the authors evaluate the added value of including a short-term dynamic borefield model to the controller and show that using a constant COP results in a bang-bang behavior of the heat pump, while with an accurate prediction of the COP the operation is smoother, saving 0.46, 1.86% and 2.71% for low, average and high electricity-to-gas price ratios respectively.

A Methodology for Long-Term Model Predictive Control of Hybrid Geothermal Systems: The Shadow-Cost Formulation

Iago Cupeiro Figueroa, +2 more
- 25 Nov 2020 - 
TL;DR: This paper proposes a methodology that includes a shadow-cost in the objective function to take into account the long-term effects that appear in the borefield, and shows that the formulation with the shadow cost is able to optimally use the active regeneration, reducing the overall operational costs at the expenses of an increased computational time.

Convex Optimization

Stephen Boyd, +1 more
TL;DR: In this article, the focus is on recognizing convex optimization problems and then finding the most appropriate technique for solving them, and a comprehensive introduction to the subject is given. But the focus of this book is not on the optimization problem itself, but on the problem of finding the appropriate technique to solve it.
