Virtual inertia analysis of photovoltaic energy storage systems based on reduced-order model

Frontiers in Energy Research, 2023
The problem of non-ideal inertia of the photovoltaic energy storage system (PVESS) may occur due to unreasonable voltage control parameters. In response to this issue, this paper establishes an equivalent reduced-order model (EROM) for PVESS.
