6 FAQs about [Photovoltaic inverter control flow chart]

How a PV inverter control the voltage of a PCC?

In this control strategy, the voltage of PCC is tracked by PV system in real time. When the voltage of PCC is normal, inverter will output in the way of maximum power point tracking (MPPT).When the voltage of PCC exceeds the upper limit, the inverter will regulate the voltage using the remaining capacity preferentially.

How to regulate a photovoltaic smart inverter?

However, should regulation be conducted with the voltage-power control technique of the photovoltaic smart inverter mentioned, the mains voltage Vgrid would increase to the root-mean-square value of 220 V (1 p.u.), which would maintain the mains voltage at a stable value.

What is a smart solar PV inverter system?

It also describes the operating principles and models of different subsystems in the power circuit and control circuit of a smart PV inverter system. The smart solar PV system is constituted by three subsystems: power circuit, voltage source converter control circuit, and smart inverter controllers. Each of these constituents is also described.

How does a photovoltaic inverter work?

Usually, when no abnormal fluctuation occurs at the voltage of a PV grid-connected system, the photovoltaic inverter generally controls both the output voltage and current under sine wave and the same phase, so the output PF becomes 1.0.

What is the output voltage of a photovoltaic smart inverter?

Regarding research and development (R&D) of the photovoltaic smart inverter, the inverter researched and manufactured as per this paper was specified with input DC voltage at 400 V, output AC voltage at the root-mean-square value of 220 V, and sine wave at a frequency of 60 Hz. 3.1.

How does a grid-connected photovoltaic inverter work?

Then, the voltage-power control technology was added to the grid-connected photovoltaic inverter. When the grid voltage p.u. value is between 1.0 and 1.03, the smart inverter starts voltage-power regulation, reducing the real power output to 1440 W, and absorbing the system’s reactive power to 774 VAr.
