The article presents an improved method for determining the permissible power generated by photovoltaic power plants, taking into account the influence of load and power converter parameters. The proposed approach is based on the construction of diagrams in active and reactive power coordinates (P-Q) with the allocation of areas of permissible and prohibited operating modes according to the criterion of total harmonic distortion of voltage.
