考虑柔性负荷的电-气综合能源系统低碳经济调度方法

Low Carbon Economic Dispatch Method of Electricity Gas Integrated Energy System Considering Flexible Load

传统的多能源系统只能对热电联供,以及冷热电联供系统进行单独分布式利用,无法形成能源耦合的有机整体,导致多能源系统运行成本较高,为解决上述问题,在考虑柔性负荷的基础上研究电-气综合能源系统低碳经济调度方法。分析电-气综合能源系统的工作流程,并通过计算柔性负荷预测误差值建立调度模型,进而在考虑弃风成本以及污染物排放成本的基础上求解目标函数最小值,实现低碳经济的有效调度。根据实验的对比结果可知,在安装P2G设备实现低碳的基础上,考虑柔性负荷的电-气综合能源系统低碳经济调度方法的综合成本相比最少,仅为2.241。

The traditional multi energy system can only make separate distributed use of cogeneration and CCHP,which can not form an organic whole of energy coupling,resulting in high operation cost of multi energy system.In order to solve the above problems,the low-carbon economic scheduling method of electricity gas integrated energy system is studied on the basis of considering flexible load.This paper analyzes the work flow of the power gas integrated energy system,and establishes the scheduling model by calculating the flexible load forecasting error value,and then solves the minimum value of the objective function on the basis of considering the wind abandonment cost and pollutant emission cost,so as to realize the effective scheduling of low-carbon economy.According to the experimental results,on the basis of installing P2 G equipment to achieve low-carbon,the comprehensive cost of low-carbon economic dispatch method considering flexible load is the least,which is only 2.241.
