含光伏的冷热电联供(CCHP)园区微网中有储冷、储热和储电多种类型储能装置,其合理协调配置能够对日负荷曲线进行削峰填谷和平抑光伏出力的不确定波动,进而提高微网运行的安全性和经济性.该文采用盒式不确定集描述光伏出力和冷热电负荷的不确定波动特性建立含光伏的CCHP园区微网中储冷、储热和储电多类型储能的协调鲁棒优化配置模型.该双层优化模型以微网年等值投资和运行费用之和最小为目标函数,通过采用Benders分解法,将双层优化问题分解为寻找某个场景下的配置方案主问题和寻找微网典型日运行费用最大的极端场景子问题进行交替迭代求解,以得到对于光伏出力和冷热电负荷不确定波动具有鲁棒性的储冷、储热及储电装置的协调优化配置方案.最后,以某个CCHP园区微网为例,通过与确定性优化配置方案和只优化配置蓄电池储能方案的比较,表明鲁棒配置方案更有利于平抑光伏出力和负荷的不确定波动,有效提高微网运行的安全性,同时多类型储能协调配置比只配置蓄电池储能方案的经济效益更好.
