Large-scale photovoltaic (PV) penetration reduces system damping and causes stability problems on off-grid distribution systems. The single-machine equivalent method is typically used to simplify the full-order model by ignoring the differences in PVs. However, this results in substantial errors.
Until storage capabilities, demand-response and flexibility systems become more widespread, keeping up the momentum of PV installations in novel deployment forms can serve as a bridge to bolster investors' confidence and mitigate market risks.
Discussion This paper presents a proposed Cascaded H-bridge multilevel converter for PV systems connected to a medium-voltage grid. The proposed converter is mainly based on a high-frequency transformer topology. Instead of the PV supplying a single-phase power grid, it supplies a three-phase power grid.
Conclusion This study determined the stability of the system using the interval of the oscillation mode, according to the linear relationship between the oscillation mode and operating condition of the off-grid distribution system with PV penetration. The system is stable when the maximum operating condition does not exceed the imaginary axis.
