Inverter-based generation is growing today in the residential, commercial, and utility segments. This article will explore how modern inverter controls can have a positive effect on today's evolving electrical grids in the utility sector. I will examine the inverter protection mechanisms used to keep dc-side and ac-side faults from causing damage to the inverter. Inverter grid supporting functions, along with voltage and frequency ride-through, provide keyhttp://www.SHUTTERSTOCK.COM/SERGIOSH http://www.SHUTTERSTOCK.COM/SURASAK_PHOTO
