Operation Evaluation Code for Wind-Photovoltaic-Energy Storage Power Stations

This document, GB/T 47032-2026, is a Chinese national standard issued on January 28, 2026, and implemented on May 1, 2026. It specifies the code of operation evaluation for wind-photovoltaic-energy storage power stations, covering general requirements, evaluation procedures, evaluation data, evaluation indicators and calculation methods, analysis and evaluation, and traceability methods. The standard applies to wind-storage, photovoltaic-storage, and wind-photovoltaic-storage combined power stations. It includes terms and definitions, symbols, and normative references to related standards such as GB/T 36549, GB/T 51311, and DL/T 7936. Key evaluation indicators include joint operation hours, joint operation factor, energy utilization rates for photovoltaic and wind subsystems, and reliability indicators. The document provides detailed calculation methods for these indicators and includes informative and normative annexes for operation evaluation data and calculation methods for wind power, photovoltaic, and energy storage subsystems. It was drafted by major Chinese electric power research institutes and companies, with main drafters including Qin Shiyao and others.
