Abstract
To secure the reliability of power systems with high penetration of distributed energy resources (DERs), requirements such as IEEE Std 1547–2018 with standardized functionality and interoperability, have been revised to strengthen the grid connection standards for DER. In addition, as the requirements for the test procedure were revised, it has become important to judge whether DERs can automatically operate in accordance with the revised requirements. This paper presents a functionality verification of interoperable DERs (IDERs) based on IEEE Std 1547.1–2020 test procedures. The IDER was designed to have the functionality that the functions satisfied the grid-connected standard and interoperability that its utility was connected to the DER interface via SunSpec Modbus. The type test for functionality verification was performed through the system validation platform (SVP) program, which allows all relevant hardware to be operated from the SVP for evaluation. The type test of IDER was conducted by that hardware consisting of a grid simulator, IDER inverter, battery simulator, and a power analyzer was built, and these were automatically operated by the SVP. The results of several type tests are verified in detail. From the results obtained, it can be confirmed that the IDER designed in this study successfully passed the type test for five functions.
