Inertia reduction due to inverter-based resource (IBR) penetration deteriorates power system stability. which can be addressed using virtual inertia (VI) control. There are two types of implementation methods for VI control: grid-following (GFL) and grid-forming (GFM). There is an apparent difference among them for the voltage regulation capability. https://poolsproductscanadas.shop/product-category/above-ground-sanitation/
