COMPARATIVE STUDY ON ENERGY UTILIZATION OF MULTI-ENERGY COMPLEMENTARY SYSTEMS WITH DIFFERENT ENERGY STRUCTURES

针对中小型多能互补发电系统,以粒子群算法为优化手段,以单位能量成本最低为目标,建立容量配置优化模型,对比探究3种不同能量结构系统的能量利用效果。以内蒙古希拉穆仁为例,搜集一年内的日均风能、光能数据进行离散化处理,模拟某社区一年的耗能数据作为负载,在此基础上求解系统的最优容量配比。以3种系统最优配比方案计算年运行数据,求解单位能量成本、能量成本组成、能量利用率和温室气体排放量。通过对数据的分析对比,探究系统能量组成结构对能量利用所产生的影响。

This paper makes a comparative study on the energy utilization effects of three different energy structure systems for small and medium-sized multi-energy complementary power generation systems.A capacity allocation optimization model is established for each system,with particle swarm optimization as the optimization method,and the lowest unit energy cost as the goal.Taking Xilamuren of Inner Mongolia as an example,the daily average wind energy and light energy data are collected for discretion within one year,and the energy consumption data of a community is simulated as a load.Based on this,the optimal capacity ratio of the system is obtained.Next,based on the optimal ratio scheme,the annual operating data,unit energy cost,energy cost composition,energy utilization rate and greenhouse gas emissions are sequentially solved.Through the analysis and comparison of the data,the impact of the energy composition structure of the system on the energy utilization is studied.
