An open-source virtual testbed for a real Net-Zero Energy Community

• An open-source virtual testbed in Modelica for studying Net-Zero Energy Communities. Physics-based and data-driven models are both considered to provide flexibilities. All the validated against real measurement. A software framework optimizing design operation with testbed. comprehensive evaluation on a demand-response control strategy this Communities (NZECs) critical assuring sustainability resilience of modernized power systems. System modeling helps overcome technical challenges designing operating NZECs. In paper, we present an NZEC based Florida, USA. This consists two sets models: (1) higher-fidelity physics-based that consider interaction between subsystems studied capture fast dynamics, (2) lower-fidelity require fewer resources establish and/or run. measurements from NZEC. addition, includes simulation streamlines processes thus allows use developed form To demonstrate usage testbed, case study is conducted where building-to-grid integration evaluated via simulation. The results suggest tested significantly smooths draw community does not sacrifice thermal comfort great extent.
