Solar farm cable layout optimization as a graph problem

Energy Informatics, 2022
We introduce the Solar Farm Cable Layout Problem (SoFaCLaP), a novel graph-theoretic optimization problem. SoFaCLaP formalizes the task of finding a cost-optimal cable layout in a solar farm where PV string positions are already determined but the ...

Process‐informed co‐optimization of liquid air energy storage and data centers under off‐design thermodynamic operation

AIChE Journal, EarlyView.
Abstract The rapid growth of AI data centers (AIDCs) is intensifying stress on power systems and exposing operators to volatile electricity markets. This work develops a process‐informed co‐optimization framework that integrates liquid air energy storage (LAES) with AIDC operation. Unlike black‐box storage models, the proposed formulation captures LAES

Locally Ideal Formulations for Piecewise Linear Functions with Indicator Variables [PDF]

, 2013
In this paper, we consider mixed integer linear programming (MIP) formulations for piecewise linear functions (PLFs) that are evaluated when an indicator variable is turned on.

Operations Research‐Based Formalisation and Design of Sustainable Reverse Logistics for E‐Waste Supply Chains

Business Strategy and the Environment, EarlyView.
ABSTRACT This study demonstrates how a profitable, lean, and environmentally responsible e‐waste reverse logistics system can be designed using integrated Operations Research (OR) techniques. Addressing the growing urgency of responsible consumption (UN SDG 12) and the projected rise of the e‐waste sector to USD 137.60 billion by 2029, the research ...

Optimization of the Water Distribution Networks with Differential Evolution (DE) and Mixed Integer Linear Programming (MILP)

Journal of Water Resource and Protection, 2015
Nowadays, due to increasing population and water shortage and competition for its consumption, especially in the agriculture, which is the largest consumer of water, proper and suitable utilization and optimal use of water resources is essential. One of the important parameters in agriculture field is water distribution network.

Bieten KI‐basierte Surrogatmodelle einen Mehrwert für die Prozessoptimierung? — Untersuchungen zu praktischen Anwendungsbeispielen im C4‐Verbund Can AI‐based surrogate models offer added value for process optimization? — Investigations into practical application examples in the C4‐Verbund

Chemie Ingenieur Technik, EarlyView.
KI‐basierte Surrogatmodelle ermöglichen die Echtzeitoptimierung chemischer Prozesse durch die präzise Abbildung komplexer Zusammenhänge bei reduzierter Rechenzeit. Anhand zweier industrieller Anwendungsfälle aus der C4‐Chemie wird das Potenzial modellbasierter Optimierung systematisch demonstriert.
