可再生能源冷热电分布式供能系统智慧高效运行

Research on Intelligent and Efficient Operation of Distributed Energy Supply System With Cold Thermoelectric and Renewable Energy

当今世界能源短缺与环境污染问题日益严重,为促进人与环境的和谐发展,满足现代化城市的快速发展,须大力发展新型的能源供给系统。围绕综合能源系统,深入探究其运行特性,进而提出针对性的优化设计方法,满足负荷需求的同时实现了供能系统的节能减排。首先,建立系统能量流模型;其次,建立考虑经济、环境等因素的多目标模型;最后,以某办公建筑负荷为例,利用遗传算法优化求解该建筑在3个典型季节典型日的最优逐时工作计划,并以该系统在传统“以电定热”运行模式下的各项指标为参照,验证了本文优化调度方法的可行性。

Nowadays,the problem of energy shortage and environmental pollution is becoming more and more serious in the world.In order to promote the harmonious development of human and environment and meet the rapid development of modern cities,it is necessary to vigorously develop a new energy supply system.Based on the in⁃depth study of the operation characteristics of the integrated energy system,an optimization design method was proposed to meet the load demand and realize the energy conservation and emission reduction of the energy supply system.Firstly,the system energy flow model was established.Then,a multi⁃objective model considering economic and environmental factors was established.Finally,taking the load of an office building as an example,the genetic algorithm was used to optimize the optimal hourly work plan of the building in three typical seasons and typical days.The feasibility of the optimal scheduling method proposed was verified by referring to the indicators of the system in the traditional"Determine Heat by Electricity"operation mode.
