Nov 1, 2022 · For a specific photovoltaic inverter system, there should be an optimal PV system capacity ratio and power limit value, taking into account inverter damage and increasing power
The increase in bus voltage is used as the control signal of the PV output current to reduce the photovoltaic output current, such that the PV output power is reduced from 3000 W to the inverter power limit value of 1500 W, which meets the requirements of the inverter output power limit.
The PV works in power limit mode, and the output current of the PV is reduced by controlling the boost converter. According to the photovoltaic I–V characteristic curve, the output voltage of the PV increases as a result and moves further away from the maximum power point.
The voltage at the terminals of the power converter may limit the reactive power provision . Additional aspects, like the operation of the MPPT, of the voltage source converter (VSC) PWM or the ambient temperature can put additional limits to the capability chart .
To provide voltage support at the PCC, reactive power is injected into the grid under fault conditions as per the specified grid codes. As previously discussed, the simultaneous injection of peak active power from PVs and reactive power into the grid for voltage support can trigger the over current protection mechanism in PV inverter.
However there are limits in power, voltage and current. When attaining one of these limits, the inverter will clip the operating point on the intersection of the I/V curve and this limit. The power difference between the MPP of the arrays' I/V curve and the effective power of this operating point on the limit curves is accounted as inverter loss:
The deviation between the inverter’s power-limiting value and the photovoltaic output power under the action of the proportional–integral (PI) controller can change the duty cycle of the boost converter, which can reduce the photovoltaic output power within 1 s. The principle of this method is simple, but the response speed is relatively slow.
