Description
Various decomposition algorithms have been studied extensively in the field of OR for decades. For quite some time, researchers have applied them to energy system models (cf. references below). However, new researchers interested in the field still fight a similar uphill battle as years ago: Not many ready-to-use tools exist (especially considering the ever-growing landscape of “competing” energy system modeling frameworks), theoretical backgrounds can be hard to work through, and going from theory to practical implementations that “actually work” can be a struggle of figuring out why seemingly minor changes make or break the approach.This proposed do-a-thon aims at experimenting & discussing together with participants how Benders decomposition can be applied to (almost) any energy system model, what important topics to get familiar with, and where hidden pitfalls – that may not even discoverable in the literature – can arise.
While this topic naturally aligns well with some of the mentioned themes (like efficient - and reproducible (!) - code that lends itself well to parallelization), I wanted to point out that iterative algorithms like Benders decomposition present one of the lowest entry barriers to solve large energy system models on limited hardware (memory, “systems with blackouts”, …) due to their inherent possibility to checkpoint/resume calculations at almost any time.
