What is photovoltaic (PV) power prediction?

Abstract: Photovoltaic (PV) power prediction is a key technology to improve the control and scheduling performance of PV power plant and ensure safe and stable grid operation with high-ratio PV power generation.

How is PV module insulation assessed?

The more sophisticated methods of assessing insulation through insulation coordination methods result in a more rigorous investigation of PV module insulation than previous approaches of assessing the insulation of a PV module, which had worked well for many years but had a different, broader, performance-based nature of assessment.

What is IEC 61730 & how does it affect a PV module?

However, the IEC 61730 places greater emphasis on safety aspects related to protection against electric shock, as well as fire hazards. It is important to note that PV module components can’t be assessed in isolation from the rest of a PV module.

Do PV modules need to be updated?

As the work of IEC TC 82 has progressed, a number of new standards for PV components and balance of system equipment have been introduced. Accordingly, the requirements for the safety of PV modules must also be updated to reference these new standards and to fully leverage the benefits that can be achieved by compliance with their requirements.

Why are international standards important in the photovoltaic industry?

ABSTRACT: International standards play an important role in the Photovoltaic industry. Since PV is such a global industry it is critical that PV products be measured and qualified the same way everywhere in the world. IEC TC82 has developed and published a number of module and component measurement and qualification standards.
