Optimisation Under Uncertain Meteorology: Stochastic Modelling of Hydrogen Export Systems - Supplementary information
January 17, 2025 (v1)
Subject: Energy Systems
Keywords: Hydrogen, Non Deterministic Programming, Non-Convex Optimisation, Stochastic Modelling
This code is of a Non-Convex Mixed Integer Quadratic Programme of a hydrogen export facility. This programme is a multistage stochastic model, using inheritance based indexing in order to account for the influence of uncertainty in weather forecasting on the optimal scheduling of the export facility.

Modelling of agro-zootechnical anaerobic co-digestion for full-scale applications: Digital Supplementary material
April 22, 2026 (v5)
Subject: Uncategorized
Keywords: Anaerobic co-digestion, Dynamic Modelling, Parameter estimation
To match the growing demand for biomethane production, anaerobic digestors need an optimal and time-varying adaptation of the input diet. Dynamic co-digestion constitutes a hard challenge for the limited instrumentation and control equipment typically installed aboard full-scale plants. The development of prediction models is foreseen to support process (optimal) design and control. In this work, a rigorous framework is applied to take full-scale applicability into account while dealing with the design and training of both high-fidelity and control-oriented first-principle/grey-box models, intended to be exploited for real-time optimization and actual process control respectively.
