Unified Virtual Oscillator Control for Grid-Forming and Grid-Following Converters [PDF]

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021
A unified virtual oscillator controller (uVOC) is proposed, which enables a unified analysis, design, and implementation framework for both grid-forming (GFM) and grid-following (GFL) voltage source converters (VSCs). Oscillator based GFM controllers, such as dispatchable virtual oscillator control (dVOC), offer rigorous analytical framework with ...
