Grid-Forming Converter Design

---

Modern power systems face reduced inertia and limited short-circuit current due to increased use of converter-based resources and fewer synchronous machines. Grid-forming (GFM) converters address these issues by emulating synchronous machine dynamics, providing inertia, damping, and enhanced control of active and reactive power.

The GFM design solution shows you how to develop and test a grid-forming (GFM) converter control. The design solution allows you to: Design a generic GFM converter and analyze its transient response. Implement virtual synchronous and droop control methods to emulate inertia and enhance stability. Apply virtual impedance and current limiting fault-ride through methods. Adapt the design to a wide range of network strengths. Verify conformance to grid code GC0137.

LLC Resonant Converter Design

---

This design solution enables you to design and analyze a full-bridge LLC resonant converter. The workflow guides you through developing the converter to meet your specifications by plotting gain curves for various load conditions, quality factors, and inductor ratios.

The design solution enables you to: Develop an LLC converter that meets your specifications. Plot gain curves for different loads, quality factors, and inductor ratios. Optimize performance by adjusting quality factor and inductor ratio. Linearize the plant for control design using time-domain simulation. Design and tune the controller compensator to meet performance targets. Estimate component power loss and calculate overall efficiency with support functions.
