Solar photovoltaic power generation system grid-connected cabinet

What is a photovoltaic grid-connected cabinet?

Photovoltaic grid-connected cabinet is a distribution equipment connecting photovoltaic power station and power grid, and is the total outgoing of photovoltaic power station in the photovoltaic power generation system, and its main role is to act as the dividing point between the photovoltaic power generation system and the power grid.

What is grid-connected photovoltaic system?

Starting with an introduction in 1 Introduction, 2 Grid-connected photovoltaic system covers the basic architecture of grid-connected solar PV system, solar cell, PV array, MPPT, and filters. The DC-DC converters such as buck, boost, buck-boost, and cuk used for the grid-connected solar PV applications have been demonstrated under the Section 3.

How to control a grid-connected photovoltaic system?

The control of a grid-connected photovoltaic system can be divided into two important parts: (1) MPPT controller to extract the maximum power from the PV modules, and (2) Inverter controller, which ensures the control of active and reactive powers injected into the utility grid and the control of DC-link voltage.

What are grid-interactive solar PV inverters?

Grid-interactive solar PV inverters must satisfy the technical requirements of PV energy penetration posed by various country's rules and guidelines. Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid.

What is grid interconnection of PV power generation system?

Grid interconnection of PV power generation system has the advantage of more effective utilization of generated power. However, the technical requirements from both the utility power system grid side and the PV system side need to be satisfied to ensure the safety of the PV installer and the reliability of the utility grid.

How many kWp is a grid-connected PV system?

Ref. presented operational results of a 11.07 kWp grid-connected PV system. The system was made up by eight groups with different relationships between the inverter's rated power and the PV generator's maximum power (P Inv 0 / P PV 0).
