Validation of advanced grid functions of battery storage systems through a controller hardware-in-the-loop setup

摘要

In order to evaluate and validate new distributed energy resources (DER) by means of controller hardware-in-the-loop (c-HIL) methods, the power electronics part is modelled within a real-time system and is connected to the control panel via a customized interface. Such a setup allows advanced testing of the control system of a DER converter and its high-level grid functions (e.g. Q(U) or P(f) functions), without any safety concern, and with the possibility of testing against conditions that rarely happen in the field. This paper describes the validation of a battery storage system with advanced grid functions using a c-HIL approach. Therefore, a laboratory and field trial setup are used and validated against real measurement results, which is also presented in this paper.
