摘要

随着节能减排观念日益深入

利用太阳能等可再生能源成为解决目前严重的化石能源危机和环境污染问题的有效途径

而冷热电联供(CCHP)系统以其能效高、污染少、可以实现能源的梯级利用等特点

成为未来分布式供能系统的发展趋势。在此背景下

将太阳能与CCHP系统相结合

设计了一种能够实现太阳能光伏光热综合利用且同时满足冷热电负荷需要的联供系统。分别建立了能源、环境、经济评价3个方面的评估指标

并利用判断矩阵法将上述3个指标形成了一个综合评估指标

同时设定了系统以热定电和以电定热2种运行方式

并分别设计了3种不同控制策略。通过算例分析了系统的电制冷机最优制冷比、太阳能光伏发电最优容量和运行控制策略的评估

验证了所提模型和控制策略的有效性和可行性

为太阳能综合应用于CCHP系统提供了参考。

Abstract

With the ever-penetrating idea of energy saving and emission reduction

the use of solar energy and other forms of renewable energy has become an effective channel to solve the serious fossil energy crisis and environmental pollution. The combined cooling heating and power (CCHP) system is the development trend of the distributed energy system in the future owing to its advantages of high efficiency

less pollution and capability of realizing cascade utilization of energy. By combining solar energy with CCHP system

a system is designed which is able to realize comprehensive utilization of photovoltaic/thermal solar energy while meeting the system need of cooling

heating and electricity load. The indices of energy

environment and economic evaluation are established

and formed as a comprehensive evaluation index using the judgment matrix method. At the same time two kinds of operation modes: ordering power by heating and ordering heating by power are set. And three different control strategies are designed. With a case in point as an example

the optimal refrigerating capacity ratio of electric refrigerator

the optimal capacity of solar generator and the evaluation of operation control strategy are analyzed. Simulation results have verified the correctness and validity of the proposed model and control strategies

providing reference for integrated application of solar energy in the CCHP system. This work is supported by National High Technology Research and Development Program of China (863 Program) (No. 2011AA05A107) and National Natural Science Foundation of China (No. 51177036).
