Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.
4.The maximum current of the PV panel is higher than the Max. input current of the inverter, which causes the inverter to operate with a DC current limit, which causes the operating power to be lower than the reasonable power of the photovoltaic system.
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.
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.
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.
Usually in a photovoltaic power generation system, PV system capacity ratio R s is the ratio of the rated power of the PV array to the PV inverter, which can be expressed as (3) R s = P pv, rated P inv, rated Fig. 6. PV system capacity ratio and power limit. When the PV system capacity ratio is greater than 1, there will be excess power supply.
