However,the ionic liq-uids with surface activity are rarely reported. In this work,a series of novel ionic liquids was synthe-sized by using N-methyl-2-pyrrolidone and alkyl bromide. The physical properties of this family of ionic liquids have been characterized,which shows that these compounds have ionic liquids characteristics,surface activity and biocompatibility.展开更多
文摘兼顾电源侧多能互补与负荷侧需求响应(demand response,DR)是提升源荷侧协调发电能力的重要手段,可以促进电力削峰填谷,提高经济效益。针对冷、热、电负荷需求的随机性和不匹配性,考虑到人体对温度有一定的适应能力,文章将风、光发电机组与燃气轮机冷热电联产(combined cooling,heating and power,CCHP)系统结合,提出了一种基于综合需求响应的源荷协调CCHP微网,同时采用典型场景集考虑新能源出力的不确定性,建立优化调度模型。该模型以最小化系统经济成本为目标,利用免疫遗传算法求解,探讨了系统经济调度成本与不同需求响应模式以及温度偏差的关系,并对系统是否引入电加热设备进行讨论。算例分析表明,基于需求响应和多能互补的CCHP微网优化调度方法,能有效降低综合运行成本,具有显著的经济及社会价值。
