Comparative Transient Stability Assessment of Droop and Dispatchable Virtual Oscillator Controlled Grid-Connected Inverters

Hui Yu et al.

Summary: This article introduces an emerging approach called dispatchable virtual oscillator control (dVOC) for implementing nonlinear control of grid-forming inverters, and proposes a simple and intuitive graphical method for assessing transient stability using vector field on the circle. Comparison of transient stability between dVOC and droop control shows that dVOC exhibits more prominent transient stability features during grid faults.

A Direct Mapped Method for Accurate Modeling and Real-Time Simulation of High Switching Frequency Resonant Converters

Hossein Chalangar et al.

Summary: This article introduces a direct mapped method (DMM) for real-time simulation of high switching frequency resonant converters, which links state variables to diode statuses and provides an exact and noniterative solution to network equations. The proposed method is implemented on FPGA to simulate an LLC converter with switching frequencies up to 500 kHz, achieving a 25-ns simulation time-step for a wide range of clock frequencies, ranging from 40 to 320 MHz.
