T/CABEE 055-2023 Evaluation Standards for Building Photovoltaic-Electricity Storage-Direct Current Conversion Systems
T/CABEE 055-2023
Basic Information
Scope
Scope: This standard applies to the performance index testing and grade evaluation of photovoltaic, energy storage, DC distribution, and flexible performance in civil buildings, but it does not apply to the safety evaluation of the system. Main technical content: The standard specifies the evaluation objects, processes, basis, and design and operation two-stage grade evaluation methods of building photovoltaic, energy storage, DC distribution, and flexible performance in photovoltaic, energy storage, and DC distribution systems. It formulates evaluation indicators covering four aspects of building photovoltaic, energy storage, DC distribution, and flexible performance in photovoltaic, energy storage, and DC distribution systems, and proposes testing methods for power quality, flexible effect, and process performance indicators of building photovoltaic, energy storage, and DC distribution systems. For the first time, the standard proposes flexible performance evaluation indicators of photovoltaic, energy storage, and DC distribution systems from the perspectives of effect and process. Based on actual engineering research and testing and related studies, it establishes a comprehensive rating index system for flexible performance.
