Operation Strategy for Photovoltaic Inverters with Microgrid Support Commuting from Grid-Feeding to Grid-Forming

https://doi.org/10.58571/CNCA.AMCA.2022.048

Resumen: This work proposes an operation strategy for a single-phase photovoltaic inverter to have the capability to change its operation mode from a feeding to a forming converter within an electrical microgrid. In addition, the proposed system provides AC mains support functions through reactive power injection during fault conditions. The IEEE 1547-2018 standard is taken as a basis, which considers the need to provide support in the event of low/high voltage variations, outside the normal operating limits. To meet some of the control objectives, a passivity-based control (PBC) is used. In order to validate the operating conditions and AC mains support functions some simulations are carried out.
