Abstract
This paper evaluates the performance of coordinated control across advanced distribution management systems (ADMS), distributed energy resources (DERs), and distributed energy resource management systems (DERMS) using an advanced hardware-in-the-loop (HIL) platform. This platform provides a realistic laboratory testing environment, including accurate dynamic modeling of a real-world distribution system from a utility partner, real controllers (ADMS and DERMS), physical power hardware (DERs), and standard communications protocols. One grid service—voltage regulation—is evaluated to show the performance of the coordinated grid automation system. The testing results demonstrate that the coordinated DERMS and ADMS system can effectively regulate system voltages within target operation limits using DERs. The realistic laboratory HIL testing results give utilities confidence in adopting the grid automation systems to manage DERs to achieve system-level control and operation objectives (e.g., voltage regulation). This helps utilities mitigate potential risks (e.g., instability) prior to field deployment.

This paper presented the performance evaluation of coordinated voltage regulation across advanced distribution management systems (ADMS), distributed energy resource management systems (DERMS), and distributed energy resources (DERs) using an advanced HIL platform
We presented the implementation details of this example HIL platform, including co-simulation of the utility distribution feeder in real-time, the communications and gateway in the ADMS, the communications and control algorithms in the DERMS hardware controllers (Heila coordinator and Heila local controllers), and the closed-loop PHIL testing of six hardware
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Transformative changes, notably at the distribution level, are taking place where increasing numbers of distributed energy resources (DERs)—such as renewable generation devices, energy storage devices, and flexible loads—are becoming prominent considerations. This requires the grid planners and operators to modernize electric grids as uncontrolled/uncoordinated DERs may cause issues to the electricity grids, such as overvoltage problems. The utility industry is exploring ways to leverage DERs to enhance system operations, paving the way for distribution-level markets, and offer new services to customers [2]
