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 generation.
When the optimal PV system capacity ratio and power limit value are taken, the annual damage of the IGBT in the photovoltaic inverter is 0.847% and the net increase of power generation is 8.31%, realizing the increase of photovoltaic power generation while the annual damage of IGBT and power generation loss due to power limit is relatively low.
The limitation is rather done at the inverter level, or more exactly at the PV array level. The only way of limiting the power is to not produce it, i.e. to displace the operating point on the array I/V curve, in order to draw just the necessary power. This is the job of the inverter.
However, during the peak period, the PV output power is large, thus causing damage to the photovoltaic inverter. In response to this problem, the literature proposed a novel control strategy to limit the power generation, thereby improving the PV inverter lifetime.
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:
PV system capacity ratio and power limit. When the PV system capacity ratio is greater than 1, there will be excess power supply. The output power should be maintained when the photovoltaic array power supply is lower than the power limit level.
