System setting and control parameters.
| Description | Value |
|---|---|
| Bus voltage | DC: 1000 V; AC: 380 V (Vrms, phase-phase), (f = 50 Hz) |
| AC-side filter | L = 0.9 mH, C = 250 μF; |
| Default loads | Local loads: PDGi = 10 kW; |
| Common loads: PC = 40 kW | |
| Droop control | mPi = 3/70000, nQi = 4/11000; |
| Pri = Qri = 0 | |
| Primary control PI parameters | Outer voltage loop: kp = 8, ki = 12 |
| Inner current loop: kp = 0.24, ki = 0.01 | |
| Secondary control PI parameters | kpω = 0.5, kiω = 1.2; kpE = 0.5, kiE = 1.6 |
