Universal Dual-Port Grid-Forming Control: Bridging the Gap Between Grid-Forming and Grid-Following Control [PDF]

IEEE Transactions on Power Systems, 2023
We analyze a dual-port grid-forming (GFM) control for power systems containing ac and dc transmission, converter-interfaced generation and energy storage, and legacy generation. To operate such a system and provide standard services, state-of-the-art control architectures i) require assigning grid-following (GFL) and GFM controls to different ...

A Comparative Study of Grid-Following and Grid-Forming Control Schemes in Power Electronic-Based Power Systems

Power Electronics and Drives, 2023
Along with de-carbonisation, the penetration of power electronic converters has increased, and the power system has become a power electronic-based power system. In such a situation, the stability of the power system faces great challenges.

A Unified Grid-Forming and Grid-Following Primary Control Design With Optimized Enforcement of Grid Operational Constraints

IEEE Access, 2023
A novel, unified control design is proposed for software-defined inverters (SDIs) to operate in either grid-forming (GFM) or grid-following (GFL) mode in AC grids/microgrids and to switch between the two modes seamlessly.

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 ...

Enhanced Frequency Control for Power-Synchronized PLL-Less Grid-Following Inverters

IEEE Open Journal of the Industrial Electronics Society, 2023
This article presents an enhanced power-synchronized grid-following inverter (ePSGFLI) for reliable and stable integration of renewable energy resources into the grid. By eliminating the use of a phase-locked loop (PLL) in the control loop, the ePSGFLI resolves instability issues commonly associated with conventional PLL-based grid-following inverters (

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

IEEE Journal of Emerging and Selected Topics in Power Electronics
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.
