基于能值分析和多目标决策法的CCHP-PV-Wind系统综合性能评估研究

为充分利用丰富的新能源,满足用户多样化能源的需求,可采用含新能源的系统实现冷热电联供.当新能源作为电源或辅助冷热源时,可减少环境压力,但多种能源形式会导致不确定性、能源利用率低且成本升高,需要新的方法对含新能源的冷热电联供(CCHP-PV-Wind)系统的优劣进行评估.提出采用基于模糊层次分析(Fuzzy-Analyt...

Comprehensive performance evaluation of a CCHP-PV-Wind system based on energy analysis and a multi-objective decision method

In order to make full use of abundant new energy resources and meet the demand for diversity of energy use,the system containing new energy resources can be used to realize the combination of heat and power supply.As a power source or auxiliary cold and heat supply,it can reduce environmental pressure.However,various energy forms will lead to uncertain,lower energy use and higher cost.New methods are needed to evaluate the advantages and disadvantages of a CCHP-PV-Wind system.A MODM based on Fuzzy-AHP and AEW is proposed to establish an index system and calculate weight.An energy index is introduced to describe the sustainability of the system,and Kendall’tin Copula theory is used to deal with the correlation between CCHP and CCHP-PV-Wind systems.Finally,energy theory is applied to evaluate and analyze both systems based on a selected building in the western part of China.The research results can provide some reference for the comprehensive use of new energy resources in China.
