Approach for handling controller conflicts within multi-functional energy storage systems

Abstract

The integration of modern energy storage systems (ESS) into power grids allows the implementation of different use cases (UCs). However, the simultaneous activation of such UCs could lead to potential conflicting behaviour. Hence, this study assesses the causes of conflicts within multi-functional ESS. A methodology for the identification and handling of conflicts is suggested using a model-driven architecture approach together with the well-known smart grid architecture model (SGAM). The main goal of this study is to demonstrate the usability of SGAM for the identification of potential controller conflicts. As a main result of this investigation, the SGAM alone does not allow the identification of all possible types of conflicts; it needs to be complemented by other models.
