Multi energy complementary distributed energy system architecture and integrated energy system design

研究针对当前能源利用效率低下、环境效益差等问题,为促进能源清洁生产、就近消纳,提升区域能源系统对能源的利用效率,实现系统稳定性、节能性,提出了并设计了一种基于分布式能源的多能互补系统架构及综合能源系统设计方案。通过设计综合能源系统以及系统评价,比较了多能互补功能方案与保守功能方案的价值,得出本地可再生能源在系统输入能值的比例达到71%,而保守功能方案这一比例仅为11%。实践证明其与传统分供系统相比能源利用率更高,具有较高的经济效益,能够确保区域不同分布式能源系统互补、优化调度的顺利实现。

Aiming at the problems of low efficiency of energy utilization and poor environmental benefits,in order to promote clean energy production,nearby consumption,improve the efficiency of energy utilization of regional energy system,and realize system stability and energy saving,this paper proposes and designs a multi energy complementary system architecture and integrated energy system design scheme based on distributed energy.Through the design of comprehensive energy system and system evaluation,the value of multi energy complementary function scheme and conservative function scheme is compared.It is concluded that the proportion of local renewable energy in the system input energy value is 71%,while the proportion of conservative function scheme is only 11%.It has been proved that compared with the traditional distributed energy system,it has higher energy utilization rate and higher economic benefits,and can ensure the smooth implementation of complementary and optimal scheduling of different regional distributed energy systems.
