A Novel Comprehensive Benefit Evaluation of IEGES Based on the TOPSIS Optimized by MEE Method

Abstract

The integrated electricity–gas energy system (IEGES) coordinates the power system and natural gas system through P2G equipment, gas turbines and other coupling components. The IEGES can realize wide-range and long-distance transmission of electricity, heat and natural gas, and truly realize large-scale cross-regional energy supply in space. At present, the theoretical system applicable to the comprehensive benefit evaluation of the IEGES has not been established, and the economic, environmental and social benefits of the system are still at a preliminary study stage. Therefore, the comprehensive benefit evaluation model of the IEGES is constructed, and the integrated benefit evaluation indicator system of the IEGES is designed along the investment and planning, energy supply, equipment operation, power distribution and terminal user. Through the combination of subjective and objective indicator weighting methods, the weights of each indicator are clarified and the matter-element extension theory (MEE) is used to improve the technique for order preference by similarity to ideal solution (TOPSIS), and the comprehensive benefit evaluation model of the IEGES is established. Finally, taking Beijing Yanqing IEGES, Tianjin Eco-city No. 2 Energy Station and Hebei IEGES III as an example, the practicability and effectiveness of the evaluation indicator system and model are verified.

Environmental Production Efficiency in the European Union Countries as a Tool for the Implementation of Goal 7 of the 2030 Agenda

“…The TOPSIS method was used to determine synthetic measures. A detailed description of this method and examples of its application can also be found in the papers [78][79][80][81][82][83][84][85][86]. This method is often used in the literature to study customer preferences [78][79][80][81][82].…”

“…It is also suitable for large systems with large samples and many indexes. Moreover, its mathematical calculation process is moderate, and it is widely used in many fields, such as urban resilience evaluation [ 29 , 30 ], policy benefit evaluation [ 31 , 32 ], public health decision making [ 33 ], and so on.…”

Comparative Analysis of Long-Distance Transportation with the Example of Sea and Rail Transport

“…For the analyzed issue in the thesis, the multi-criteria analysis method was chosen-the technique for order of preference by similarity to ideal solution (TOPSIS). TOPSIS is used in various fields such as IT, space, and transport [20][21][22][23][24][25][26][27]. Supporting the decision-making process in the TOPSIS method allows, among others:…”
