Abstract

The grid code compliance of a 50 MW battery energy storage system (BESS) with a power

plant controller (PPC) is validated through detailed analysis and testing. A real-time capable

test setup is developed, integrating the PPC via Control-Hardware-in-the-Loop (CHiL) as the

device under test (DuT). By connecting the controller to the simulated point of

connection (POC), the test environment replicates field conditions. Various test cases evaluate

PPC performance under critical grid code requirements, while additional tests, such as power

oscillation damping (POD), address additional specifications from the national grid operator

and the developer. To ensure reproducibility and user-friendliness, test execution is automated

via a Python API-based graphical user interface (GUI). The successful validation of both gridforming

and grid-following operation demonstrates how CHiL testing mitigates field

integration risks.
