虚拟惯性对含恒功率负载直流电网稳定性的影响

Virtual inertia is an effective control approach to attenuate sudden voltage changes during transient events in low-inertia dc grids. While methods have been proposed to implement virtual inertia, its impact on dc grid stability in the presence of constant power loads (CPLs) remains unclear. In this letter, we perform a rigorous stability analysis for dc grids with CPLs powered by virtual-inertia-...
