Thesis Evaluation of a Hydro Power System Production Planning Model

About the thesis 

Vattenfall R&D is responsible for conducting business driven technical development that creates value for the company and helps us realize Vattenfalls strategy. We develop cost effective safe and sustainable solutions to improve the infrastructure of Vattenfall assets including Hydro Wind Nuclear SKB Heat and Distribution

Production Planning Optimization Models for hydropower systems have a profound usage at Vattenfall in the operational planning of the assets and as a support tool in e.g. outage planning investment studies and environmental studies. For this both commercial tools and in-house developed tools are utilized. The in-house tools are under constant development based on needs in different studies and the inspiration for this development sometimes come from the research community.

This master thesis work will assess a published hydropower optimization model 1 and compare it with the in-house model at Vattenfall R&D. This will involve preparation of the required input data setting up a suitable set of test cases execute the cases and evaluate the result. Since part of the input consist of relations not presently available also estimation of these relations from different data sets will be part of the addition testing the sensitivity to different input parameters will be part of the scope.

An implementation of the published model is available online via GitHub and is written in the Julia language. The software developed for the assessment during the thesis work may also be written in Julia. However the in-house model is written in Matlab so another option is to implement the published model in this environment. The best alternative will be decided early in the project based on initial findings during the project start-up.

Diversity & inclusion - in everything we do 

At Vattenfall we build on the fact that diverse teams can outperform homogeneous teams. But we can only unleash and leverage the power of diversity if we make everybody feel included. Read more about our important work on diversity & inclusion Vattenfall 

We have been electrifying industries powering homes and transforming life through innovation and collaboration for more than 100 years. Empowered by our goal we are determined to enable fossil free living within one generation. To succeed we as one of Europes leading energy companies must be fossil-free ourselves. 

But thats not enough. Thats why we are looking beyond our own industry to see where we can really make a difference. 

Join us in our journey towards a fossil-free life within one generation.
