摘要

综合能源系统（integrated energy system，IES）以多能互补和能量阶梯利用为核心，将大大提高系统的能量利用率，实现多种能流互补优化。通过建立冷-热-电综合能源系统，以系统总运行成本最低为目标函数，考虑设备模型约束和功率平衡约束，采用日前负荷模拟综合能源系统经济优化运行；同时考虑到系统在冬、夏季运行工况差异较大，采用分季调节运行模式，利用分支界定（branch and bound，B-a-B）算法求解优化模型。仿真结果表明，系统能量供给平衡，"源-荷-储"互补搭配性强，系统运行灵活、经济高效，同时，系统污染气体排放量少，有利于环境保护。

Abstract

The integrated energy system (IES) is based on multi-energy complementarity and energy ladder utilization

which will greatly improve the energy utilization of the system and achieve multiple energy flow complementary optimization. A cold-thermal-electric IES was established. The objective function is the lowest total operating cost of the system. Considering the constraints of equipment model and power balance

the daily load is used to simulate the economic optimal operation of the comprehensive energy system. Considering that the operating conditions of the system vary greatly in winter and summer

the operation mode is adjusted by the seasons

and the branch and bound (B-a-B) was used to solve the optimization model. The simulation results show that the system energy supply balance

"source-load-storage" complementary collocation

the system is flexible

economical and efficient

and at the same time

the system emits less pollutant gas

which is conducive to environmental protection.
