考虑多元负荷需求响应的综合智慧能源系统协同优化调度 [PDF]
全球能源互联网, 2022 考虑综合智慧能源系统管理中电负荷和热负荷的可调度价值，提出了一种考虑电热多元负荷需求响应的综合智慧能源系统协同优化调度模型及方法。首先，利用用户对供热舒适度感知的模糊性及热网在传输过程中的热惯性，将热负荷作为能源系统中的柔性负荷加入到综合智慧能源系统的优化调度中。同时，综合考虑了电负荷与热负荷的不同类型的需求响应，构建了电热多元负荷综合需求响应模型。其次，引入能质系数将能量的“质”和“量”相结合，以系统用能效率最优为目标函数，考虑正常运行条件下电气热系统运行约束，建立了综合智慧能源系统协同优化调度模型 ...
