摘要
作为能源互联网的基础,综合能源系统将是未来能源发展的重要方式,实现区域内综合能源系统的协调运行会变得至关重要。在考虑到需求侧天然气与电能同样具有商品属性,类比电负荷的峰谷分时电价策略,首先搭建天然气和电能峰谷分时价格及热能负荷响应数学模型。其次建立了以运行成本最低为目标函数,对供需平衡和供储能设备等设立约束的电热气联合供应的区域综合能源系统模型。算例分析表明,考虑到电热气需求侧响应将会优于不考虑或者只考虑单一和两者响应,可达到运行成本更低、削峰填谷、减少弃风弃光和提高能源利用率等优势。
As the foundation of the energy internet, integrated energy system will be an important way for future energy development, and the coordinated operation of integrated energy system in the region will become crucial. Considering that the demand side natural-gas and electric energy have the same commodity properties, this paper analogizes the peak-to-valley time-of-use price strategy of electricity load. First, it sets up the mathematical model of natural-gas and electric energy peak-to-valley time-of-use price and thermal load response;second, it establishes a regional integrated energy system model with the combined electricity, heat and natural-gas supply, which takes the minimum operating system operating cost as the objective function and supply-demand balance and energy supply-storage equipment as the constraints. The example analysis shows that considering the demand side response of the electricity, heat and natural-gas is superior to not considering or considering only the single and the two responses. This can achieve lower operating costs and peak-load shifting, reduce abandoned new energy power, and improve energy utilization.
