A Control Parameters Self-Adjusting Method for photovoltaic inverter considering the variation of inductance
The variation of inductance is the reason for the instability of photovoltaic (PV) inverter system. To this end, a control parameters self-adjusting method considering the variation of inductance is proposed to enhance the anti-interference ability. The basic control method is to use grid-connected...

| description | The variation of inductance is the reason for the instability of photovoltaic (PV) inverter system. To this end, a control parameters self-adjusting method considering the variation of inductance is proposed to enhance the anti-interference ability. The basic control method is to use grid-connected current control and capacitor-current-feedback method to suppress resonance. Based on the Routh Criterion (RC), a simple Routh Array enumeration rule is proposed. Discrete Routh Criterion (RC) is selected as the stability analysis method to obtain the stability range of the control parameters. The control parameters self-adjusting method can enhance the anti-interference ability of system under variations of inductance, which is proved by comparative experiments. |
