Photovoltaic panel generator test process

Can a stand-alone photovoltaic system be tested?

Abstract: Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load. The methodology includes testing the system outdoors in prevailing conditions and indoors under simulated conditions.

Why should PV generators be integrated into the grid?

With the increased integration of PV generators into the grid, the system operators start to require PV generators have capabilities to stay online during the fault, and provide the active power and the reactive power supports when being required to do so.

Why is modeling a solar photovoltaic generator important?

Modeling, simulation and analysis of solar photovoltaic (PV) generator is a vital phase prior to mount PV system at any location, which helps to understand the behavior and characteristics in real climatic conditions of that location.

Does dynamic modeling work on a PV generator?

Although much dynamic modeling work on the PV generator has been reported in the literature, research on how to revise the generic model including to tune the parameters to match the input–output characteristics between the model and the real device is far less satisfactory. Specifically, the following studies need further attention:

How does a photovoltaic system work?

The heart of a photovoltaic system is the solar module. Many photovoltaic cells are wired together by the manufacturer to produce a solar module. When installed at a site, solar modules are wired together in series to form strings. Strings of modules are connected in parallel to form an array.

How does a PV power station support grid voltage recovery?

According to the grid regulations, the PV power station is required to support the grid voltage recovery by injecting the reactive current. In addition, after the fault is cleared, the active power of the PV station should recover to the pre-fault value with a change rate of at least 0.3 pu/s.
