Learn how you can design, implement, and test the controller code for a 3-phase grid-tied solar inverter using Simulink. The goal is to develop a controller that can adhere to grid codes and maintain inverter grid connection during upset conditions.
We begin by modeling the photovoltaic (PV) system, solar inverter, and grid load with Simulink and Simscape Electrical. This model is used to design and tune closed-loop and supervisory control algorithms for maximum power point tracking (MPPT), grid synchronization, and low voltage ride through (LVRT). With Embedded Coder, the control algorithms are used to generate and deploy optimized C code to a Texas Instruments C2000 Piccolo™ MCU. Finally, the implemented code is tested for a variety of emulated grid fault scenarios using a hardware-in-the-loop (HIL) simulation of the PV system, inverter, and grid load running on a Speedgoat real-time target machine using Simulink Real-Time.
