An Alternative Control Structure for Grid-Following Converters of Inverter-Based Resources
IEEE Open Access Journal of Power and Energy, 2023 In this paper, an alternative control structure of grid-following control is proposed and applied in inverter-based resources (IBRs). An IBR’s grid-following control normally employs Power/Voltage (P/V) control strategy to control the output real ...

External Inertia Emulation Controller for Grid-Following Power Converter [PDF]
IEEE Transactions on Industry Applications, 2021 The advent of renewable energy has posed difficulties in the operation of power systems whose net inertia is becoming critically low. To face such challenges, grid-forming power has been one of the potential solutions pursued by the industry and research community. Although promising, grid-forming power converters are still immature for mass deployment

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 ...

Modelling of grid-following current-controlled VSC
Journal of Physics: Conference Series, 2023 Abstract The voltage sourced converter (VSC) is a basic element in the grid connected solar-PV system that used in converting the DC-generated power from the solar-PV to AC power compatible with the utility grid. In this paper, a grid connected, three phase, two level VSC model and its control technique are simulated.
