Adaptable equivalent circuit model for electrochemical storage elements as a part of energy system modeling for ZEB
Résumé
In the context of global energy transition, reduction of building energy consumption takes an important role. In order to achieve buildings with yearly net zero energy, integrating energy production such as Building-Integrated Photovoltaic (BIPV) can be a low cost solution. However storage elements become necessary to optimize their functioning in terms of energies exchanges. This paper is focused on electrochemical storage elements; their modeling in order to choose the best one in term of efficiency and lifetime. To simulate their behavior in the context of BIPV, a simple model must be designed to take into account the complexity of the system. A modeling technique for electrochemical storage elements with few parameters is presented in this paper for easy integration in building-scale simulations, which aims to be easily adaptable to new technologies and future evolutions of energy storage elements. The ADREAM building of LAAS-CNRS, a ZEB research platform and demonstrator, provides the necessary experimental data for this work.
