6 FAQs about [Three-phase three-wire photovoltaic inverter control]

What is a control strategy for a three-phase PV inverter?

Control strategy A control strategy is proposed for a three-phase PV inverter capable of injecting partially unbalanced currents into the electrical grid. This strategy aims to mitigate preexisting current imbalances in this grid while forwarding the active power from photovoltaic panels.

Are three-phase smart inverters suitable for grid-connected photovoltaic system?

The main purpose of this paper is to conduct design and implementation on three-phase smart inverters of the grid-connected photovoltaic system, which contains maximum power point tracking (MPPT) and smart inverter with real power and reactive power regulation for the photovoltaic module arrays (PVMA).

What is a photovoltaic inverter control strategy?

The main objective of the inverter control strategy remains to inject the energy from the photovoltaic panels into the electrical grid. However, it is designed to inject this power through unbalanced currents so that the local unbalance introduced by the inverter contributes to the overall rebalancing of the grid’s total currents.

Can a three-phase photovoltaic inverter compensate for a low voltage network?

Thus, this work proposes to use positively the idle capacity of three-phase photovoltaic inverters to partially compensate for the current imbalances in the low voltage network but in a decentralized way.

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.

How do PV inverters control a low-voltage network?

Thus, a control method for PV inverters is presented, so that they inject unbalanced currents into the electrical grid with the aim of partially compensating any current imbalances in the low-voltage network where inverters are connected, but in a decentralized way.
