Cost-effective Planning of Decarbonized Power-Gas Infrastructure to Meet the Challenges of Heating Electrification

no code implementations31 Aug 2023 Rahman Khorramfar, Morgan Santoni-Colvin, Saurabh Amin, Leslie K. Norford, Audun Botterud, Dharik Mallapragada

Applying the framework to study the U. S. New England region in 2050 across 20 weather scenarios, we find high electrification of the residential sector can increase sectoral peak and total electricity demands by up to 56-158% and 41-59% respectively relative to business-as-usual projections.

Learning Spatio-Temporal Aggregations for Large-Scale Capacity Expansion Problems

1 code implementation16 Mar 2023 Aron Brenner, Rahman Khorramfar, Saurabh Amin

We evaluate aggregation outcomes over a range of hyperparameters governing the loss function and compare resulting upper bounds on the original problem with those obtained using benchmark methods.

Electric-Gas Infrastructure Planning for Deep Decarbonization of Energy Systems

no code implementations28 Dec 2022 Rahman Khorramfar, Dharik Mallapragada, Saurabh Amin

The transition to a deeply decarbonized energy system requires coordinated planning of infrastructure investments and operations serving multiple end-uses while considering technology and policy-enabled interactions across sectors.

Graph Representation Learning for Energy Demand Data: Application to Joint Energy System Planning under Emissions Constraints

no code implementations24 Sep 2022 Aron Brenner, Rahman Khorramfar, Dharik Mallapragada, Saurabh Amin

Specifically, we focus on efficiently extracting a set of representative days from power and NG data in respective networks and using this set to reduce the computational burden required to solve the GTEP.
