| 摘 要： | 分布式综合能源微网(DIEM)具有冷/热/电/气多能耦合的典型特征,如何进行包含冷热电联供(CCHP)和多种储能设备的运行优化,一直是现阶段研究工作的重点和难点之一。文中建立了储能设备和CCHP系统模型,基于电/冷/热和烟气余热,利用平衡等式约束、储能设备充放能约束以及系统各个设备上下限约束,并通过配置权重系数,以一个运行周期内运维总成本和CO 2总排放量为综合运行优化目标。构建了某大学城典型场景,以储能设备为例,配置储冷设备的容量分别为0 MW,2 MW,4 MW,分析了储能容量对DIEM运行优化的影响。配置合适的储能设备容量,一个周期内的综合运行优化目标越低,越能兼顾经济性和碳排放要求。

| Abstract: | Distributed integrated energy microgrid has the typical characteristics of cold/heat/electricity/gas multi energy coupling.How to optimize the operation of the combined cooling,heat and power supply and a variety of energy storage equipment has been one of the key and difficult research work at this stage.In this paper,the model of energy storage equipment and combined cooling heating and power(CCHP)system are established,which are based on the constraints of balance equation of electricity/cooling/heating and flue gas waste heat utilization,charge and discharge of energy storage equipment,upper and lower limits of each equipment in the system,the comprehensive operation optimization objective is operation economy and total CO 2 emission in one operation cycle by configuring weight coefficient.A typical scenario of a university town is constructed,taking the cold storage equipment as an example,the capacity of energy storage equipment are 0 MW,2 MW,4 MW,and the influence of energy storage capacity on the operation optimization of distributed energy microgrid is analyzed.With the appropriate capacity of energy storage equipment,the lower the comprehensive operation optimization goal in a cycle,the better the requirements of economy and environmental protection can be considered. |
