DC Microgrid with Droop Control of Two Parallel Converters

Approx. component budget: Rs. 8,000 - 14,000

Objective

Show how multiple sources share a load without a central controller.

What you will build

Two DC-DC converters feeding one DC bus that share load automatically using droop control, with a controllable load and monitoring.

Results you can expect

• Load sharing ratio vs droop gain
• Bus voltage regulation
• Response to a source failure
• And stability with a constant-power load

What you will learn

Decentralised control, droop characteristics and microgrid stability.

Tools and notes

Two buck converters, Arduino/STM32 each, current sensors, electronic load, scope. Keep voltages at 24 V or below and add fuses to each source.

Resume points from this project

• Built and tested DC Microgrid with Droop Control of Two Parallel Converters; objective: show how multiple sources share a load without a central controller.
• Measured and analysed load sharing ratio vs droop gain and bus voltage regulation; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
