能源互联网多能源系统最优功率流

Optimal Energy Flow of Multiple Energy Systems in Energy Internet

基于能量枢纽模型,提出能源互联网中以电力、天然气、热力三大供能网络为主的多能源系统协同运行优化方式,考虑各能源传输网络的特点,促进分布式可再生能源出力。将弃风电量作为优化指标之一,综合分析能源消耗及环境效益,并通过弃风供热进行风电消纳,有效减少弃风电量。与传统的以热定电运行模式相比,多能源协同运行优化方式具有较高的综合收益。

This paper suggested an integrated view of multiple energy systems with renewable in energy intemet. Multi-period optimal energy flow in electrical, nature gas and district heating system were studied with the comprehensive consideration of energy consumption, green gas emissions and renewable energy output based on the well-accepted energy hub model. Renewable energy was effectively promoted in the coordinated operated system. Compared to the traditional system operation method, wind power accommodation was realized by supporting part of the heat loads in energy internet. A better comprehensive benefit can be achieved.
