摘要
为探讨分布式能源站(distributed energy station,DES),这一能源系统中的重要能源转换环节,研究其站内规划与多站之间的多能互补特性,并兼顾考虑能量的“数量”与“品质”双重价值属性,将量质协同约束纳入DES规划范畴,为此,该文提出一种多区域电-冷-热互联DES量质协同规划方法。首先,建立DES互联冷管道传输模型;其次,采用能源集线器建立考虑电-冷-热互联协同、新能源接入的DES综合模型;在此之后,基于混合整数线性规划,以互联系统总成本最低为优化目标,引入㶲效率约束,构建多区域电-冷-热互联DES量质协同规划模型;最后,通过算例验证了规划模型的合理性与可行性。
To explore the distributed energy station(DES),an important energy conversion link in the energy system,the characteristics of the station planning and multi-station multi-energy complementarity were studied,and the dual value attributes of"quantity"and"quality"of energy were taken into account,and the constraint of quantity and quality coordination was brought into the scope of DES planning.This paper proposes a multi-region electric-cold-thermal interconnection DES quantity and mass collaborative planning method.Firstly,the transmission model of the DES interconnected cold pipeline is established.Secondly,the DES integrated model,which considers electric-cold-thermal interconnection and new energy access,is established using an energy hub.After that,based on mixed integer linear programming,an exergy efficiency constraint was introduced to build a DES mass-quantity cooperative programming model for multi-region electric-cold-thermal interconnection with the lowest total cost as the optimization goal.Finally,an example is given to verify the rationality and feasibility of the programming model.
