Communication is often an afterthought when designing or deploying new distributed energy resource (DER) projects. In practice, though, these communication issues can make or break integration projects when deployed to the energy grid. See how HIL Compatible devices together with model-based system engineering (MBSE) can be used to safely validate communication and control issues prior to system deployment with real hardware, and drastically simplify the integration and commissioning process of new renewables, microgrids, and virtual power plants (VPPs).
