Abstract: Battery energy storage is becoming an important part of modern power systems. As such, its operation model needs to be integrated in the state-of-the-art market clearing, system operation, and investment models. However, models that commonly represent operation of a large-scale battery energy storage are inaccurate.
Battery Energy Storage is regularly deployed for applications such as frequency control, load shifting and renewable integration. In order to assess the relative benefits of both existing and new deployments of BESSs, modelling and simulation of these systems can provide a fast and reliable method of evaluation.
The intermittent nature of renewable sources points to a need for high capacity energy storage. Battery energy storage systems (BESS) are of a primary interest in terms of energy storage capabilities, but the potential of such systems can be expanded on the provision of ancillary services.
However, models that commonly represent operation of a large-scale battery energy storage are inaccurate. A major issue is that they ignore the dependence of the charging power on the battery state of energy.
Each battery cell is modeled using the Battery (Table-Based) Simscape Electrical block. In this example, the initial temperature and the state of charge are the same for all cells. There is no coolant flow modeled in this example. The battery module is shorted with a 0.1mOhm resistor.
Based on the current state of charge, the parameters of the equivalent circuit are evaluated, and by knowing the parameters of the circuit and the current, the actual voltage at the terminal of the battery is evaluated and used as a reference point of the DC voltage source.
