Solar generation has increased rapidly worldwide in recent years and it is projected to continue to grow exponentially. A problem exists in that the increase in solar energy generation will increase the probability of grid disturbances.
Then there is a large disturbance or outage in the power grid, conventional inverters shut power off to energy sources and wait for the signal from the rest of the grid that it is safe to turn back on. This process is called “grid-following.” Grid-forming inverters allow solar and wind power to restart the grid independently.
A more effective IEEE approach described by IEEE Std 929-2000: 19 This is due to the forced restraint on current and voltage harmonics. In addition, this ensures that

The grid accepts AC (alternating current power) but many renewables make DC (direct current power). Inverters change DC to AC so that the grid can accept the power. Solar, wind, and batteries make DC power, and they all use inverters to put power on the grid. Solar, wind, and batteries are all Inverter Based Resources (IBRs).

this function can actually help the grid to self-heal from a disturbance. Even when the ride-through functions are activated, the inverter disconnects the solar system when more severe grid disturbances warrant doing so (Beach 2003; ACEG 2014; CPUC 2014). One way that inverters can help the grid regain stability

Impact of Grid Strength To understand the impact of grid strength on negative-sequence current of solar inverters during the restoration period, we considered a weak grid operating condition in solar PV test system II by increasing the impedance of the transmission line between POC and grid bus to three times larger than the original value.
Nevertheless, due to the high magnitude of the negative-sequence current injection from solar inverters during the grid restoration period, the negative-sequence current may be also larger than the 50Q pickup threshold, and the element may mistakenly operate during the grid restoration period, even after the grid disturbance is cleared.
It was found that solar inverters can act as negative-sequence sources to inject negative-sequence currents into the grid during the restoration period. The negative-sequence current can be affected by different operating conditions such as the number of inverters in service, grid strength, and grid fault types.
The future of intelligent, robust, and adaptive control methods for PV grid-connected inverters is marked by increased autonomy, enhanced grid support, advanced fault tolerance, energy storage integration, and a focus on sustainability and user empowerment.
Due to the advanced inverter control algorithms, the inverter-based resources present fault responses different from conventional generators, which can fundamentally affect the way that the power grid is protected.
The tripping event in Texas — which spanned 500 miles — and other, similar incidents have been tied to the inverters that convert electricity generated by solar, wind and battery storage systems to the power used on the grid.
