Tight MILP Formulation for Pipeline Gas Flow with Linepack
T. Klatzer, S. Wogrin, D. A. Tejada-Arango +1
In integrated power and gas energy system optimization models (ESOMs), pipeline gas transmission with linepack is a particularly complex problem due to its non-linear and non-conve…
Enhancing Time Series Aggregation For Power System Optimization Models: Incorporating Network and Ramping Constraints
David Cardona-Vasquez, Thomas Klatzer, Sonja Wogrin
Power system optimization models are large mathematical models used by researchers and policymakers that pose tractability issues when representing real-world systems. Several aggr…
Time series aggregation for optimization: One-size-fits-all?
Sonja Wogrin
One of the fundamental problems of using optimization models that use different time series as data input, is the trade-off between model accuracy and computational tractability. T…
Power-Based Generation Expansion Planning for Flexibility Requirements
Diego A. Tejada-Arango, Germán Morales-España, Sonja Wogrin +1
Flexibility requirements are becoming more relevant in power system planning due to the integration of variable Renewable Energy Sources (vRES). In order to consider these requirem…
Enhanced Representative Days and System States Modeling for Energy Storage Investment Analysis
Diego A. Tejada-Arango, Maya Domeshek, Sonja Wogrin +1
This paper analyzes different models for evaluating investments in Energy Storage Systems (ESS) in power systems with high penetration of Renewable Energy Sources (RES). First of a…
