“…This testbed contains a Danfoss VLT-302 inverter with LCL filters, a sensor box, and other components. The testbed and the most commonly used control blocks are described in more detail in [18,21,22]. The inverter was synchronized and coupled to the grid at the Point of Common Coupling (PCC) at the beginning of the experiment (before the active power step).…”

“…The RVSG control method allows the emulation of the same behavior of the virtual inertia in a VSC, improving the VSG method presented by Driesen and Visscher [17]. This control scheme is similar to the VSG method, which is located in the active power control loop [18]. The proposed control approach allows for fulfilling the premise of decoupling active and reactive power, achieving better performance.…”

Virtual synchronous generator (VSG) control is based on the fact that the line impedance in a microgrid is highly inductive. This assumption was made due to the emulation of the stator winding of an electrical machine. This concept can affect the controllability of a microgrid with complex line impedance, generating deviations in the chosen operation point. To overcome this issue, additional techniques must be implemented. This paper describes a novel mathematical approach that uses the power line characteristics in a microgrid to rotate the power control reference frame and proposes a new control method called a “Rotated Virtual Synchronous Generator” (RVSG). This RVSG control approach integrates the effect of complex impedance on the microgrid’s operation and adjusts the reference frame accordingly to improve the system’s stability and performance. The use of this proposed mathematical approach in microgrids allows the further emulation of virtual inertia in microgrids that lack inertia. Finally, a comparison between RVSG control and the classical virtual synchronous generator method is carried out to show that it allows the improvement of the transient power response, power quality, stability, and performance, mainly in microgrids with complex line impedance.
