Regional integrated energy system evaluation method based on energy Internet layered architecture

Abstract

The invention discloses a regional integrated energy system evaluation method based on an energy Internet layered architecture, and the method comprises the steps: taking the geographic position of equipment in an energy station system as an Internet system node, and marking a connection port address of the corresponding equipment at the Internet system node; using a power transmission line connected with equipment in an energy station system as an Internet system link, marking the power transmission line on the Internet system link as information, and it can be understood that a string of nodes and links between a signal sending node and a signal receiving node establish a power grid topological structure for a path of an Internet system; power analysis of power grid equipment is facilitated, the power analysis and application requirements of an energy station system are met, and online fault diagnosis and early warning of a power system are achieved.

Description

technical field [0001] The invention relates to the technical field of energy stations, 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 characteristics of energy sources, and promotin...

Problems solved by technology

In the existing research, the first one is to evaluate the benefits of CCHP system and gas turbine system, and select system investment cost, primary energy consumption, NOx, etc. as the evaluation indicators of 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 efficiency evaluation index system from the energy, device, distribution network, and user links, and integrate indicators reflecting economic, social, and environmental benefits into each link, taking into account the internal energy coupling relationship of the regional integrated 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
