Simulink DC Microgrid Model
Budget: $30 – $250 USD
I need a complete Simulink-based representation of a low-voltage DC microgrid that demonstrates stable power-sharing through droop control. The model must combine two renewable sources—a solar panel array and a wind turbine—each tied to the DC bus through appropriate DC-DC converters. A battery pack, modelled with its bidirectional converter, will serve as the main energy-storage element. Please include a representative mix of static and time-varying loads plus a simple load-management block so I can toggle demand profiles during simulation.
Key points I expect you to cover
• Implement conventional voltage–current droop control (or another proven droop variant) so the sources share power proportionally under changing irradiance, wind speed, and load events.
• Keep each subsystem modular and clearly labelled for easy parameter tweaking.
• Scope blocks or dashboards that track bus voltage, individual source currents, State-of-Charge, and total load power.
• Fully comment the model so I can follow your control loops, converter settings, and assumptions.
Deliverables
1. A single .slx file that runs in the latest stable release of Simulink/Simscape Electrical without extra paid toolboxes.
2. A brief PDF or Markdown note (max 3 pages) outlining model structure, parameter values, and how droop gains were selected.
3. Screenshots or short animation showing a typical 10-second run where the battery, solar, and wind units share load smoothly while bus voltage stays within tolerance.
I will test by altering irradiance, wind speed, and turning loads on/off; the microgrid should remain within ±5 % of its nominal DC bus voltage and distribute current per the droop settings.
