Table 1 idref and iqref under different operating conditions
Criterions | idref | iqref |
|---|---|---|
Vpcc > 0.9 | idref =  id0ref | iqref  =  0 |
0.2 < Vpcc < 0.9 and \(i_{qref} \le \sqrt {I_{\max }^{2} - i_{d0ref}^{2} }\) | idref  =  id0ref | iqref  =  α∙(m-Vpcc) |
0.2 < Vpcc < 0.9 and \(i_{qref} > \sqrt {I_{\max }^{2} - i_{d0ref}^{2} }\) | idref  =  \(\sqrt {I_{\max }^{2} - i_{qref \, }^{2} }\) | iqref  =  α∙(m-Vpcc) |
