Operation Evaluation Procedures for Combined Wind, Solar and Energy Storage Power Stations

1 Scope

GB/T 47032-2026 is the Chinese national standard covering judging a hybrid wind-solar-storage plant as one station - the output it actually delivers against forecast, the curtailment avoided by the storage, the round-trip losses, the availability of each part and the indicators that make two such plants comparable. First edition, in force since 1 May 2026. It was issued on 28 January 2026 and has been in force since 1 May 2026, as a first edition. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the overall requirements, evaluation procedures, evaluation data, evaluation indicators and calculation methods for the operation evaluation of combined wind, solar and energy storage power stations. Analysis, evaluation, and traceability methods. This document applies to the operational evaluation of wind-storage, solar-storage, and combined wind-solar-storage power plants.
