Fluid Queue Models of Renewable Energy Storage

Gareth Jones, Peter Harrison, Uli Harder, Anthony Field
2012 Proceedings of the 6th International Conference on Performance Evaluation Methodologies and Tools  
In this extended abstract we introduce an approximation algorithm for the evaluation of networks of fluid queues. Such models can be used to describe the generation and storage of renewable energy.  ...  We discuss how our algorithm would be applied to an example where the approximation performs very well, and note a modification to the model which would result in a poorer result.  ...  Recently the authors of this paper argued that fluid queue networks can describe the problem energy producers face in routing and allocating storing energy produced from renewable sources [8] .  ...
