Abstract
In the context of the world’s transition to more environmentally friendly activities, energy plays a big role. The replacement of fossil fuels for renewable energies will be pivotal in the following years but it will not be an easy process.
Redox flow batteries and, specifically, vanadium redox flow batteries can be a helping hand in that path. They are unique energy-storing technologies that could complement and solve some of the current drawbacks of renewable energies.
The aim of this project is to, first, understand the general principles behind the redox flow batteries. The second goal is to develop a working model of a vanadium redox flow battery based on existing mathematical equations that describe their behaviour. The third and final objective is to design a control system for the battery so that it could automatically and reliably deliver a desired voltage set arbitrarily (within its capabilities).
To achieve the goals of the project, a first analysis of redox flow batteries is conducted, including the search for the equations that will be able to govern the dynamic system. With these equations and to be able to linearize the system, equilibrium points will be found and analysed. With a linear system and while working close to its equilibrium points, it will be possible to design a controller that can ensure the functioning of the battery at a certain voltage. After this process, some simulations will be run to observe the behaviour of the system that has been built, placing emphasis on factors such as its reliability or its capacity to work under different conditions.
To finish off, conclusions will be drawn from all the previous work, research and results, bearing in mind that the field of redox flow batteries is still at its early stages.
