Abstract
The work presented in this report documents the development of a Li-Ion battery energy storage system (BESS) multi-physics model based on the limited data available to potential investors in such systems. BESS are essential for the development of a stable and sustainable power grid. Simultaneously they are an asset whose value must be assessed beforehand by a party interested in investing in them. Due to the complex behaviour in both operation and degradation processes of batteries, they are inherently difficult to assess in terms of long-term performance.
For that reason there are many existing models that try to approximate the behaviour of batteries. None of the models investigated displayed sufficient accuracy or flexibility necessary for a reliable simulation of BESS behaviour. Therefore, through a series of short- and long-term testing, extensive literature review and derivation of manufacturer-provided values of the system a new model is generated. This data-restricted multi-physics simulation (DREMUS) is then turned into a tool for industrial application.
The tool developed is capable of modelling through best possible approximation the electrical, thermal behaviour of a battery storage system based only on the data available before making an investment decision. It further was designed easily modifiable so additional data can be added. The tool was used for a case study to assess its long term viability. It was found that under the investigated value streams and current market conditions the system was not viable.
The model and tool can be widespread applied to all carbon-based Li storage applications and allows thus more efficient implementation of BESS throughout the UK power system.
