6 FAQs about [EU grid connection requirements for photovoltaic inverters]

When designing a PV plant a suitable sizing of inverters?

When designing a PV plant, a suitable sizing of the PV inverters shall be of special interest in order to comply with the national requirements on reactive power capability at maximum (RfG, Article 21 (3) (b)) and below maximum capacity (RfG, Article 21 (3) (c)).

Should grid-forming inverters be mandatory?

However, there seems to be a general consensus among grid code experts from TSOs and academia that requirements for grid-forming inverters in grid codes are needed sooner than later. There is still some debate on whether the functionality should be mandatory for the above-mentioned reasons.

Can a British system operate at 100% inverter penetration?

Studies published by the University of Strathclyde together with British TSO National Grid ESO have shown that stable operation of the British system at 100% inverter penetration would be possible with only 10% of units equipped with grid-forming functionality.

Can Island power systems run on grid-forming inverters?

A number of small, megawatt-scale island power systems run on grid-forming inverters as of 2021, such as Graciosa in Azores, Portugal; Saint Eustatius in the Caribbean; and Tetiaroa in French Polynesia (Schömann et al., 2019), and the technology has long been established in kilowatt-sized off-grid systems.

What is a non-mandatory specification for grid-forming inverters?

When integrated into the grid code, this will be a non-mandatory specification that outlines technical requirements for potentially installed grid-forming inverters, but does not generally require the functionality itself (National Grid ESO, n.d.).

What are European grid codes?

For example, the European (European Union [EU] level) grid codes include network connection codes, operating codes and market codes. Because grid codes are the result of the stakeholders’ landscape and the power system organisation structure that is in place, each jurisdiction can have a different grid code structure.
