There may be benefits to enabling this capability in inverters, such as less expensive zero or slightly negative active power voltage support (compared with synchronous machines) and more dispersed resources supporting automatic voltage control.
At nominal voltage, the inverter-based resource can supply 1.0 pu apparent power continuously to the grid.38 Each inverter has a capability curve similar to a synchronous machine, which is affected by terminal voltage of the inverter. At higher and lower voltage, the reactive capability is restricted at leading and lagging output, respectively.
The specifications are designed to be independent of specific technology and relate to all types of inverter-based resources, such as wind, solar PV, and battery energy storage systems (BESSs). This guideline uses examples of each interchangeably.
Inverter ac breakers require at least three to four cycles to operate (and often much longer for the types of breakers used at the inverter terminals), and therefore are not effective protection mechanisms for mitigating sub-cycle transient overvoltages.
Inverter protection should be coordinated with the use of surge arresters with inverter protective tripping functions to securely protect against transient, sub-cycle overvoltages. Surge arrestors applied to the inverters can clamp transient overvoltages to acceptable levels while still ensuring continuous operation of the inverter.
