T/CAQI 502-2026 The comprehensive evaluation of virtual carbon reduction in intelligent microgrids for architecture

Scope

This standard applies to the pre-evaluation during the design phase and comprehensive evaluation during the operation phase of virtual carbon emission reduction for intelligent microgrids in buildings. It provides specific evaluation criteria for the four dimensions of "source, storage, load, and grid". 1. Evaluation System and Grade Classification Indicator Classification: The comprehensive evaluation system consists of control items (evaluated as meeting or not meeting standards), scoring items (10 core indicators), and additional bonus and penalty points. Star Rating: The evaluation grades are divided into five levels: basic, one star, two stars, three stars, and four stars. When all control items are met, it is considered a basic level; scores of 60, 70, 80, and 90 points correspond to one to four stars, respectively. 2. Distributed Power Virtual Carbon Emission Reduction ("Source" Category Indicators) Core Indicators: Including virtual carbon emission reduction from renewable energy utilization, renewable energy utilization rate, adjustable distributed power installed capacity ratio, and self-balancing rate. Control Item Thresholds: Require renewable energy installed power to be no less than 50kW; renewable energy utilization rate to be no less than 30%; adjustable distributed power or storage installed capacity ratio to be no less than 10%; and self-balancing rate to be no less than 25%. 3. Energy Storage Virtual Carbon Emission Reduction ("Storage" Category Indicators) Energy Storage Forms: Building microgrids can use forms such as cold/heat storage, electrochemical storage, and electric vehicle V2G. Core Indicators: Including energy storage capacity virtual carbon emission reduction, self-consumption rate, V2G, and line power fluctuation rate. Control Item Thresholds: Storage capacity should not be less than 50kWh; self-consumption rate should not be less than 40%; charging stations should have V2G functionality with a power of no less
