PV Battery DC Microgrid with ANFIS MPPT in MATLAB

Bidirectional Converter Design

1. Battery Selection: The design starts with a 10V to 12V battery with a 40Ah capacity.

2. Converter Type: A bidirectional converter is chosen with an output voltage of 220V.

3. Component Selection: The design specifies values for inductors, capacitors, resistors, and switches based on calculations
   

Solar Power System Design

1. Solar Panels: The system uses four solar panels connected in series, each with a rating of 250W, 30.7V maximum voltage, and 8.15A maximum current.

2. Boost Converter: A boost converter is employed to increase the voltage from the solar panels to the desired output level.

3. MPPT Controller: An MPPT (Maximum Power Point Tracking) controller is likely used to optimize power generation from the solar panels (though not explicitly mentioned).

System Integration and Testing

• The system combines the bidirectional converter and the solar power system with battery backup.

• A load of 50% of the maximum capacity (around 240W) is simulated.

• The system is tested under varying irradiation conditions (simulated by adjusting a parameter).

Results

• The system successfully maintains a load voltage around 220V and a load current around 2.2A.

• The battery charges when solar power exceeds load demand and discharges to supplement the load when solar power is insufficient.
