Obtaining of an Equivalent Circuit of a Redox Flow Battery

https://doi.org/10.58571/CNCA.AMCA.2023.077

Resumen: This paper focuses on obtaining an equivalent electrical circuit (EEC) type model for a flow battery, with parameter identification from data generated by simulating an electrochemical model of the system. The model with the EEC structure is more versatile to be used, for example, in design and testing of control and energy management strategies in hybrid systems, since it can be simulated in conjunction with other electrical circuit models of power electronics devices. The EEC model is obtained from the data resulting from the simulation of the electrochemical plant before an input signal rich in frequencies, estimating the model parameters by nonlinear least squares fitting, implemented in an algorithm available in the Matlab – Simulink platform.
