Table 6 Quantitative assessment of transient performance under step change of active power
Mode of operation | Parameter | Value | |
|---|---|---|---|
Fixed weight factors | Variable weight factors | ||
Step change in active power (Pref: 0 → 10 kW) (Qref is zero VAR) | Settling time [ms] | 1.77 | 1.82 |
Max.│Cross coupling on Q│ [kVAR] | ≅ 1.60 | ≅ 0.18 | |
Peak overshoot of P | nil | nil | |
Weight factor wp | 1 | 0.1 | |
Weight factor wq | 1 | 1 | |
Steady state PF* | ≅ 0.999 | ≅ 0.999 | |
Worst PF during cross coupling | ≅ 0.982 | ≅ 0.990 | |
THD of current* [%] | ≅ 3.350 | ≅ 3.350 | |
