“3060”双碳目标势必带来分布式发电(DG)在公共配电网中的大量接入,传统按接入电压等级平均分摊成本的配电网收费方式会引发连锁反应的“死亡螺旋”问题,因此,适应高渗透率DG并网的未来配电网收费方式将成为保障P2P等能源共享用户公平性和配电网高效可持续运行的重要基础。首先,该文根据世界各国对未来配电网收费方式的探索,分别从DG自发自用和余量上网两种模式下的配电网收费方式进行总结分析,同时,将配电网收费分为容量收费、电量收费和需求收费三个方面,比较其优劣和适用性;然后,对典型国家的配电网收费方式结合其电力市场运行特点进行对比分析;最后,结合中国的DG分布情况,从实际运行的角度提出对配电网收费方式的建议。
