Regional comprehensive energy system evaluation method based on energy internet hierarchical architecture

Abstract

The invention particularly relates to a regional comprehensive energy system evaluation method based on an energy internet hierarchical system architecture, and the proposed regional comprehensive energy system evaluation method covers each level of an energy internet physical layer, an information layer and a value layer, and comprehensively considers multiple aspects such as economy, efficiency,safety and environmental protection. Compared with an existing evaluation index, the method is more comprehensive and systematic, each index has a specific quantitative calculation method, a comprehensive evaluation result is obtained through dimensionality reduction by adopting a weighted summation method, and engineering implementation is easy. The evaluation index system provided by the invention can be used for quantitative analysis in the aspects of operation and design of the regional comprehensive energy system, guides related research and work of investment constructors, design planning units and system operators, and improves the construction and operation level of the regional comprehensive energy system.

Description

technical field [0001] The invention belongs to the technical field of comprehensive energy planning and operation analysis, in particular to a regional comprehensive energy system evaluation method based on the energy Internet layered architecture. Background technique [0002] Energy Internet has become an inevitable trend in the future development of the energy field, a hot topic in international research, and a major demand for my country's energy development. The Energy Internet aims to solve environmental problems, energy flow barriers and energy reform issues in the process of replacing traditional fossil energy with clean energy, and to develop a good development foundation for integrated energy systems and energy market services. The regional integrated energy system is an important physical carrier of the Energy Internet, and it is a frontier for exploring the internal operating mechanism of different energy sources, giving full play to the complementary characteri...

Problems solved by technology

In the existing studies, the first one is to evaluate the benefits of the CCHP system and the gas turbine system, and select the system investment cost, primary energy consumption, and NOx as evaluation indicators for evaluating the comprehensive energy system. The energy comprehensive benefit evaluation index system covers three aspects of economic, social and environmental benefits, but there are few secondary indicators

The second is to establish a regional comprehensive energy benefit evaluation index system from the links of energy, equipment, distribution network and users, and integrate indicators reflecting economic, social and environmental benefits into each link, taking into account the energy coupling relationship within the regional comprehensive energy system , and more comprehensively reflect the economic, environmental and social benefits of comprehensive energy, but the selection of indicators in this indicator system is relatively coarse, and the coverage of benefit indicators is insufficient

[0005] Judging from the existing results, research on the comprehensive energy system benefit evaluation index system has been carried out at home and abroad, but there is a lack of systematic indicators that can reflect the construction and operation level of each level of the Energy Internet architecture. In addition, the comprehensive energy efficiency that can be applied to actual project evaluation The evaluation index system and its evaluation criteria have not yet been fully established
