摘要
分布式冷热电联供是一种多能源综合互补、高效利用的有效方式。本文以广州某2000 m^(2)公寓楼为例构建集“源、储、荷”三位一体的分布式微能源网系统,建立了固体氧化物燃料电池、太阳能集热器等系统关键设备数学模型,基于理想点法优化了系统的集热场面积、热水罐体积、基岩储热容量等关键设计参数,使系统具有最佳的综合性能。结果表明,在集热场面积872m^(2)、热水罐容积240 m^(3)、基岩储热容量73 MWh时,系统年综合性能最佳:系统的年总成本可降至234.6万元,能量利用率从43.8%显著增加至70.5%。
Distributed combined cooling,heating and power supply is an effective way of multienergy comprehensive complementary and efficient utilization.This paper takes a 2000 m^(2) apartment building in Guangzhou as an example to construct a distributed micro-energy grid system integrating“source,storage and load”,establishes a mathematical model of key equipment of the system,studies the annual comprehensive performance of the system,and optimizes it based on the ideal point method.The key design parameters of the system,such as the area of the heat collection field,the volume of the hot water tank,and the heat storage capacity of the bedrock,are analyzed.The results show that when the area of the heat collection field is 872 m^(2),the volume of the hot water tank is 240 m^(3),and the heat storage capacity of the bedrock is 73 MWh,the system can obtain the best comprehensive performance:the annual cost of the system can be reduced to 2.346 million yuan,and the energy utilization rate is significantly from 43.8%Increase to 70.5%.
