T/CPSS 1003-2025 Roof-top photovoltaic power grid access power quality prediction and evaluation technical specification

Scope

Main technical content: This document specifies the general requirements, evaluation process, data collection, evaluation methods, and evaluation reports for the prediction and evaluation of power quality of rooftop photovoltaic systems connected to the public power grid. This document is applicable to 10 kV and lower public power grids, with a capacity of less than 6 MVA, for simplified calculations of power quality prediction and evaluation before the connection of three-phase rooftop photovoltaic systems to the public power grid. It is used to evaluate the impact of distributed photovoltaic systems on the power quality of the PCC after connection to the public power grid. Fishery-compatible and agricultural-compatible photovoltaic projects connected to the public power grid can refer to this document for implementation.
