On Grid-Interactive Smart Inverters: Features and Advancements

Blog Article

Traditionally, a grid-interactive inverter providing ancillary services is called a smart inverter.However, broader features will be required for the next generation of inverters that can be categorized as self-governing, self-adapting, self-security, and self-healing.For grid-interactive inverters, the self-governing feature can be identified as the capability of inverters to operate in grid-following and grid-forming control modes, where the self-adapting is referred to as more flexibility realized by adaptive controllers for stable dynamics of inverters under High Voltage Tripler various grid conditions.

Moreover, for supervisory control and economic dispatch in a grid with high-penetration of inverter-based power generators, a minimum communication might be necessary, but it can place grid-interactive inverters in danger of being hacked when self-security becomes essential to identify Vitamins A malicious setpoints.Furthermore, the self-healing is defined as fault-tolerance and stress reduction under abnormal conditions.It suggests that after realizing these features, an inverter is called a smart inverter.

In this paper, the advancements toward achieving these features for grid-interactive inverters are reviewed.
