摘要
随着能源互联网这一概念的提出,多能协调互补成为大家关注的焦点。文章主要研究基于电热耦合约束下的微网优化运行问题。在传统模型的基础上,文章考虑更详细的电网约束和热网约束,建立基于CCHP系统的微网新型电热耦合模型。然后,文章以日运行成本为目标进行系统运行优化,通过与传统建模方法的对比,验证利用基于电热耦合约束下的模型进行运行优化,可以使得运行方案更为精确并显著降低运行成本。
With the introduction of the concept of energy internet,multi-energy coordination and complementarity has become the focus of attention.This paper mainly studies the optimal operation of microgrid based on electrothermal coupling constraints.On the basis of the traditional model,this paper considers more detailed grid constraints and heat network constraints,and establishes a new electrothermal coupling model of microgrid based on CCHP system.Then,this paper aims at the daily operating cost to optimize the operation of the system.By comparing with the traditional modeling methods,it is verified that the model based on electrothermal coupling constraints is used for operation optimization,which is expected to make the operation scheme more accurate and significantly reduce the operation cost.
