Research On The Multi Energy Coordination Evaluation Model Of Regional Energy Internet

As the basic industry of the national economy,the energy industry is not only a prerequisite for ensuring national strategic security,but also an important guarantee for the sustainable development of the economy.With the continuous promotion of the "Internet+",the energy Internet with the smart grid as the core has proposed a new path of development and a new concept for the traditional energy industry.Compared with the traditional grid,the energy Internet pays more attention to the comprehensive and complementary utilization of various energy resources,and coordinates and optimizes the operation,which is to promote the consumption of renewable energy,enhance the comprehensive energy efficiency of regional energy supply,reduce the emission of polluting gas and realize the regional energy supply System of "low-carbon,economical,safe,high-quality" an important way to run the target.In order to ensure the reliability,economy and cleanliness of regional energy Internet operation,a comprehensive assessment of the comprehensive energy and multi-energy coordination of regional energy and Internet resources with various energy sources needs to be carried out.This paper first introduces the common multi energy coordination technology under the regional energy Internet,analyzes the concrete connotation and the action mechanism of multi energy coordination,and studies the benefits generated after the coordination of regional energy Internet and multi energy coordination from the aspects of technology,economy and society.Secondly,on the basis of the above analysis,according to the principles of comprehensiveness,objectivity,practicality and typicality,this paper constructs a multi-energy coordinated evaluation index system for energy resources from four dimensions:coordination and optimization,security and stability,economic benefits and social benefits,and give the specific calculation method of the index.Then,based on the characteristics of the index system,this paper proposes an improved projection pursuit method based on the traditional projection pursuit method,which is based on the subjective weight constraints.The multi-energy coordination comprehensive evaluation model is constructed by this method.Finally,by using this model to evaluate the three demonstration projects,the effectiveness of the evaluation model is verified,and some suggestions are put forward for the future development of the demonstration project.
