Grid Code Enablement and C-HIL Validation of Distributed Energy Resources with OpenFMB

Distributed Energy Resources (DERs) with grid support capabilities enabled by IEEE 1547-2018 must be designed and evaluated in a systematic and comprehensive way. These capabilities, which are often referred to as grid codes, surpass the base capabilities of a DER and provide opportunities to improve grid reliability through increased resiliency to disturbances, proper active-reactive response, and operational visibility. This paper introduces a methodology to add grid code functionality to legacy DERs with an OpenFMB communication framework with the ultimate objective of enabling grid support functions using Distributed Intelligence (DI). Additionally, the content below provides a framework for validating the impact of these devices using a state-of-the-art Controller Hardware in Loop (C-HIL) testbed.
