2025 绿电直供 / 直连技术交流课件，围绕绿电直连发展的背景、政策、技术、模式等展开，核心为破解国际绿色壁垒与新能源消纳难题，推动电力市场化改革。
背景上，欧盟 CBAM 等国际碳规则落地，我国企业面临碳税风险，且新能源装机激增致大电网消纳压力大，绿电直连因可物理溯源、就地消纳成为破局关键，兼具降碳成本、提升国际竞争力的战略意义。
政策方面，国家 650 号文首次制度性认可绿电直连，明确并网 / 离网分类、自发自用比例（≥60%）等要求，各地也出台试点政策，差异化明确投资主体、消纳距离、储能配置等，但存在余电上网定价不一、专线成本高等痛点。
技术上，绿电直连面临二次系统、储能推高成本，调度权责模糊等挑战，核心依托源网荷储一体化、微电网、虚拟电厂等技术，通过区块链实现绿电溯源，构网型储能保障系统稳定。
模式分为并网型和离网型，并网型依托大电网、储能配置低，适合负荷集中区域；离网型独立运行、储能成本高，适用于电网薄弱地区，并有中金乌兰察布算力基地等标杆项目落地。
