Free QuoteThe "Power Sharing" tool will allow one to allocate a specified PNom, according to the effective nominal power of the connected modules. Physically, the sub-arrays concerning a given physical Inverter are interdependent: if you define Pnom (MPPT1) in one sub-array, the Pnom (MPPT2) should be Pnom (Inv) - Pnom (MPPT1).
Integrating Grid-Following Inverters (GFLs) into power systems presents significant stability challenges, particularly in systems with reduced strength and high renewable energy penetration.
The parallel-connected inverters were controlled by a DSP-based controller. All tests followed the simulation settings. The power transfer waveforms under the different cases are shown in Figure 14. FIGURE 13. Experimental platform.
A novel DC bus controller is proposed to enhance the inertia and stability of GFLs during grid disturbances by dynamically adjusting power references based on load demand. Through mathematical modelling, small signal analysis, and MATLAB simulations, the study evaluates the effects of inverter-based resources (IBRs) on power system stability.
Note that only sub-arrays with the same inverter model can perform the power sharing among each other. You can create new configurations by drag-and-dropping a sub-array on the corresponding inverter node on the left, or by pressing the plus button. The needle gauge button also allows to equalize Pnom ratios with more granularity.
FIGURE 10. Control block diagram of the proposed control method. The proposed power sharing method aims to keep the hybrid MG system working with the lowest power capacity and to ensure accurate power transfer.
