Summary

Several large-scale solar plants have experienced significant commissioning delays due to a mismatch between the software model and on-site hardware response, sometimes even leading to project failures and bankruptcy. Typical response mismatch scenarios arise from inappropriate software modelling, incorrect responses from power quality meters, discretisation and sampling issues, communication delays, interoperability issues between multiple original equipment manufacturer (OEM) devices, etc. This paper discusses the journey of commissioning a large-scale solar plant using a pre-commissioning platform developed at the

University of Queensland, Australia. The layout of the overall plant, the schematic of the platform and the benchmarking tests on the platform are discussed in this paper. The role of the

OEM in integrating various hardware devices to form the overall platform will be elucidated.

Furthermore, the pre-commissioning tests conducted for the plant, including the real power step test, reactive power step test, frequency step test, communication failure test, and grid frequency playback test, are presented. Finally, the example scenarios of the hardware-software response mismatch identified with the help of the platform, along with the corresponding solutions, is discussed to highlight the value proposition of the platform.
