Operation and Control Technical Specifications for Combined Wind, Solar and Energy Storage Power Stations

1 Scope

GB/T 46812-2025 is the Chinese national standard covering controlling a hybrid plant as one machine - the dispatch of wind, solar and storage against a single set point, the smoothing and firming the storage provides, the state of charge management and the response to grid instructions. First edition, with the evaluation standard GB/T 47032-2026. It was issued on 31 December 2025 and has been in force since 1 April 2026, as a first edition. This page is published from the official record of the 2025 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 operation mode, power control, operational adaptability, power quality, relay protection and safety features of combined wind, solar and energy storage power stations. Technical requirements for actuators, automation and communication, network security, power metering, operation management, etc. This document applies to the operation and control of combined wind, solar and energy storage power stations connected to the grid at voltage levels of 35kV and above.
