Dynamic Headroom - Tests dynamic adjustment of headroom based on battery SOC.
Analysis: What Does This Simulation Prove?
What this proves: The "headroom" is a safety buffer below your target limit - it gives your
ESS (Energy Storage System) time to react before you exceed the limit. With dynamic headroom, this buffer adjusts
based on battery SOC: when SOC is low (<20%), headroom is high (1.0 kW) because the battery can't help much.
When SOC is high (>80%), headroom is low (0.2 kW) because the battery can quickly discharge if needed. This
maximizes your usable power while maintaining safety. Watch the SOC chart and see how limits change as the
battery charges overnight and discharges during peak hours.

Monthly Cost Impact: Based on typical Swedish effekttariff rates (~50 SEK/kW/month),
this 1.5 kW reduction saves approximately
76 SEK/month on the power tariff portion of your grid fee.
Battery Contribution: The battery discharged during 42 peak hours
with an average discharge rate of 1.8 kW to shave consumption peaks.
