Demand response (DR) has proven to show capabilities of providing ancillary services (AS) to grid operators. Advances in high speed computing and the availability of widespread and efficient network infrastructure bring tools that were otherwise inaccessible—financially or technologically—within reach. Building upon these advances, economically sound solutions to the established need for simulation testbeds for integration of distributed energy resources (DERs) systems into the power grid become available. This work presents methods of advanced power system modeling, integrated hardware design, and software development tools to develop a DR simulation testbed for grid stabilization in a power grid with a high presence of intermittent renewable generation. The result is a comprehensive package for internet of things hardware-in-the-loop simulation (iHILS) that was tested using DR aggregate control to provide stability to a grid with high integration of DERs.
