一种基于风能储能的分布式能源系统

摘要

In order to verify and study the output characteristics of distributed energy system based on the integration system of wind power generation and Advanced Adiabatic Compressed Air Energy Storage (AA-CAES),a distributed energy system with wind energy storage technology was established and parametric expressions about energy were deduced thermodynamically. The relationship between the output characteristics of distributed energy system and heat energy utilization was determined , and advantages of distributed energy system were analyzed with an example of one office building .Results show that power is decreasing with heating increasing , meanwhile cooling and the total energy output are increasing; compared with the model of power , the total energy output of distributed energy model are more on the premise of ensuring the demand of cooling and heat ,and distributed energy model is more energy-efficient when the total energy output are the same .%为了验证和分析风电与先进绝热压缩空气储能（ Advanced Adiabatic Compressed Air Energy Storage ，简称AA-CAES）集成系统用于分布式供能的能量输出特性，建立了以风能储能技术为基础的分布式能源系统模型，从热力学角度推导了与能量输出相关的参数表达式，得到了分布式能源系统冷热电输出特性与储热器中热量利用的关联性，并以某写字楼为例，分析了分布式能源系统的优势。结果表明：随系统供热量的增加，系统供电量减少，制冷量增加，且能量输出总量增加；在满足冷量和热量需求的前提下，相比供电模型，分布式供能模型有更多的供电量，而在能量输出相同的条件下，分布式能源系统模型更节能。
