摘要
在售电侧改革背景下,以区域内余剩电力的共享、融通为基本立足点,建立基于分布式能源产消者、售电商和一般用户的区域电力市场概念模型,并提出其基本决策流程。以利益相关者总体共赢为导向,耦合应用数学规划方法,分别构建产消者、售电商和一般用户的优化决策模型。针对以冷/热/电三联供系统为技术架构的典型案例进行数值分析,结果表明,售电商的购电价格在整体决策流程中占据先导地位,其不但直接影响产消者决策,亦间接影响售电商和一般用户收益。仅当购电价格处于某特定范围时,前述三利益相关者才能获得经济共赢。同时,对于售电商而言,存在使其收益最大化的最优购电价格。另一方面,区域电力融通在获得经济共赢的同时,亦可产生可观的节能效果。理论和数值分析均表明,产消者一次能源节约量与电力融通量成近似正比例关系,这主要得益于余电所附余热在产消者内部的充分利用。
