Selective PQD Power Control Strategy for Single-Phase Grid-Following Inverters [PDF]

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2023
This paper proposes the selective PQD power control strategy based on proportional-integral controllers devised in stationary abc-reference frame for single-phase grid-following inverters. Its physical behavior and mathematical model are presented in detail and the system output impedance is derived.

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 ...

Wideband Dissipativity Enhancement for Multi-Sampling Controlled Grid-Following VSCs

2022 IEEE Energy Conversion Congress and Exposition (ECCE), 2022
With the gradually decreasing cost of high-performance digital processors, multi-sampling current control is a promising method to reduce the control delay and improve the high-frequency dissipativity in grid-connected converters. Specifically, with the capacitor voltage feedforward and the inverter-side current feedback, the dissipation of the multi ...
