重磅突发！国家能源局重新修订红、黄、绿区标准！

Core Viewpoint - The National Energy Administration has released a draft guideline for evaluating the hosting capacity of distributed energy resources connected to the power system, aimed at enhancing the integration and management of distributed renewable energy sources [1][3]. Summary by Sections General Requirements - The guideline outlines the overall requirements for evaluating the hosting capacity of distributed energy resources, including system-level and equipment-level capacity calculations, result verification, and measures for capacity enhancement [10][15]. System-Level Capacity Calculation - System-level capacity calculations should be conducted annually or according to the design cycle of the power system, considering significant boundary condition changes [16]. - The capacity range for provincial administrative regions or independent control areas is determined through simulation calculations, factoring in new energy utilization rates and flexible adjustment capabilities [16][18]. Equipment-Level Capacity Calculation - Equipment-level capacity calculations should be performed quarterly, focusing on peak output times of distributed energy resources and predicting related parameters such as load and output [17][18]. Capacity Verification - Capacity verification should be conducted at the county level, ensuring that system-level and equipment-level calculations align [20][22]. Open Capacity Assessment and Classification - Open capacity assessments involve evaluating both county-level and transformer-level capacities, following a hierarchical approach [25][28]. - The classification of open capacity levels is based on the availability of space for new distributed energy resources, with specific thresholds for green, yellow, and red alerts [30][34]. Capacity Enhancement Measures - Measures to enhance the hosting capacity of distributed energy resources should ensure the safe and stable operation of the power system, including optimizing new energy utilization and upgrading existing infrastructure [36].
