Problems solved by technology

[0003] Judging from the current research status, the main consideration of the natural gas combined cooling, heating and power system is to consider the economical factor, and few scholars can comprehensively consider the evaluation index system in many aspects.
In addition, in terms of the weight of different indicators in the evaluation index system and the determination method of the evaluation matrix, empirical formulas or expert voting scoring methods are generally used at present, which have the defects of strong subjectivity and poor objectivity, and lack of scientific rationality

Embodiment

[0043] Such as figure 1 As shown, a comprehensive evaluation method for natural gas combined cooling, heating and power system is used to comprehensively evaluate multiple natural gas combined cooling, heating and power systems and determine the optimal solution. The method includes the following steps:

[0044] Step 1: Establish a hierarchical evaluation model, including an overall target layer, an index layer and a second index layer. The overall target layer is the overall target of the system solution to be evaluated, and the first index layer is the There are multiple first-level indicators corresponding to the target, and each first-level indicator corresponds to a set of second-level indicators, and all second-level indicators form a second-level indicator layer;

[0045]This embodiment comprehensively considers six aspects of economy, environmental protection, energy saving, technological advancement, reliability and safety as the first-level index of the overall evalu...

Abstract

The invention relates to a comprehensive evaluation method for a natural gas combined cooling, heating and power system, which is used for comprehensive evaluation of multiple natural gas combined cooling, heating and power system schemes. The method includes the following steps: establishing a layered evaluation model, including The target layer, the first index layer and the second layer index layer; determine the weight matrix of the first layer index and the weight matrix of the second layer index of each group of second layer index; obtain the index value of each second layer index in the system plan to be evaluated, according to the fuzzy method Determine the second-level indicator evaluation matrix corresponding to each group of second-level indicators; obtain the first-level fuzzy comprehensive evaluation set according to the weight matrix of each second-level indicator weight matrix and the corresponding second-level indicator evaluation matrix, and then obtain the first-level index evaluation matrix; The second-level fuzzy comprehensive evaluation set is calculated by the layer index weight matrix and the first-layer index evaluation matrix, and the second-level fuzzy comprehensive evaluation set is the comprehensive evaluation value of each system program to be evaluated. Compared with the prior art, the evaluation result of the present invention is objective and reliable.

Description

technical field [0001] The invention relates to a comprehensive evaluation method, in particular to a comprehensive evaluation method for a natural gas combined cooling, heating and power supply system. Background technique [0002] As people's awareness of environmental protection increases, natural gas resources, as a clean energy source, are increasingly favored by the energy industry. Natural gas Combined Cooling Heating and Power (CCHP) is a new energy utilization model that uses gas turbine equipment to provide energy supply to users that has emerged in China in recent years. Compared with the traditional power generation system and energy supply system, the natural gas combined cooling, heating and power system is closer to the user end, and does not need to build a large power grid for long-distance high-voltage or ultra-high-voltage transmission, which can greatly reduce line losses and save investment in power transmission and distribution construction cost.
