Expanding the capacity of grid-connected inverters
With the penetration of distributed energy resources (DERs), new network challenges arise that limit the hosting capacity of the network, which consequently makes the current expansion-planning models inadequate. Smart inverters as a promising tool can be utilized to enhance the. . Researchers recommended that transmission system operators consider adopting grid-forming battery energy storage systems system-wide to improve grid stability and to maximize system hosting capacity for solar and wind generation. The Energy Systems Integration Group has published a study on the. . Managing the stability of today's electric power systems is based on decades of experience with the physical properties and control responses of large synchronous generators, usually with the size of hundreds to even thousands of megawatts. Today's electric power systems are rapidly transitioning. . In contrast, grid-forming (GFM) control is an alternative method that still has to synchronize with the existing grid but maintains constant internal voltage to inject power in a steady state. . This column was launched in the last issue of the IEEE Power Electronics Magazine to look holistically at the ongoing energy transition, driven by “exponential-technologies. ” These are the areas where price declines and performance improvements, both enabled by rapid and global technology advances. .
