Includes "Smart Inverters" with autonomous functions to increase grid resilience and safety as more Distributed Energy Resources (DERs) come online.
The island grid project moved forward. With the updated solver, the storage controller settings optimized more aggressively without destabilizing the system. The simulated generator’s reactive capability—once a stubborn bottleneck—now cooperated smoothly with inverter controls. The final protection coordination diagram showed clear margins where before they had been hairline. The client’s operations manager read the report and asked, almost disbelievingly, whether the dramatic improvements came from hardware changes. Mara answered: mostly from math and careful modeling—and an update that made the math behave.

ETAP 21.0.2 is not compatible with Windows 7 or 8.1. It also does not run natively on macOS or Linux without a virtual machine (VM).
Bridges the gap between steady-state load flow and dynamic simulations, useful for varying load profiles over time.
The first sandbox run was annoyingly ordinary. Most calculations finished, relay curves aligned, bus voltages behaved as expected. Then she pushed further: a dynamic sequence where a cloud field transiently reduced PV output by seventy percent while batteries attempted to ride through. The previous version had hiccupped here—oscillations, nonphysical spikes, an odd negative damping that made her worry about the model’s numerical core. This time, the solver held. It was subtle at first: no more spurious overshoot, smoother governor response, sensible harmonics. She repeated the test with different initial conditions, and each run agreed. That quiet consistency was what she’d been waiting for.
