6 FAQs about [Optimal power generation voltage for photovoltaic inverters]

What happens if a photovoltaic inverter exceeds a voltage limit?

When the grid-connected point voltage exceeds the limit, the photovoltaic inverter outputs the corresponding reactive power. If the reactive power capacity of the inverter is insufficient, part of the photovoltaic active power is reduced to meet the reactive power demand of the system .

How reliable is a photovoltaic inverter?

IGBT reliability is the key factor affecting the reliability of photovoltaic power supplies, and the failure of photovoltaic power supplies caused by IGBT accounts for more than 30% . At present, the reliability analysis of the PV inverter focuses on inverter power devices [, ].

How do PV inverters control stability?

The control performance and stability of inverters severely affect the PV system, and lots of works have explored how to analyze and improve PV inverters’ control stability . In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. .

Why do PV inverters increase voltage?

Moreover, PV inverters are injecting a finite amount of reactive power to the system even at 100% of active power rating, thereby, increasing the voltage. Integration of additional MGs into the radial network further aggravates the system voltage as the MGs are in dispatch mode for most of the time.

What is constant power control in a PV inverter?

In general, PV inverters’ control can be typically divided into constant power control, constant voltage and frequency control, droop control, etc. . Of these, constant power control is primarily utilized in grid-connected inverters to control the active and reactive power generated by the PV system .

What is the control performance of PV inverters?
