Research On Multi Energy Complementary Optimization Model And Benefit Evaluation For Adapting To Clean Energy Consumption

Energy shortage and environmental pollution have become key challenges faced by countries around the world.In order to alleviate environmental pollution and energy shortage issues,it is necessary to increase the development and utilization of clean energy,and vigorously develop clean energy represented by wind and solar energy has become a necessary path in China’s energy transformation process.It is of great significance for achieving China’s economic growth and sustainable development.However,due to the randomness of wind and solar power generation and the inverse spatiotemporal distribution of resources and demand,the phenomenon of energy abandonment in wind and solar clean energy generation is very severe,seriously restricting the sustainable development of clean energy.In this context,the National Development and Reform Commission,the Energy Administration,and the Ministry of Industry and Information Technology have issued the Guiding Opinions on Promoting the Development of "Internet Plus" Smart Energy,proposing to focus on promoting the construction of a multi energy complementary system that is conducive to the consumption of clean energy.Through the collaborative transformation of multiple energy sources such as electricity heat gas cooling in the multi energy complementary system,energy utilization efficiency can be improved,wind and light waste phenomena can be reduced,and the level and comprehensive benefits of clean energy consumption and utilization can be promoted.In the above context,this article conducts research on a multi energy complementary system that adapts to clean energy consumption,proposes a multi energy complementary optimization model and evaluation mechanism,which has important practical significance for building a clean,low-carbon,safe and efficient modern energy system.The research content of this article is as follows.Firstly,this article systematically reviews the domestic and international development and research status of the development,construction,operation optimization,and benefit evaluation of multi energy complementary systems;Sort out the relevant policies and integrated optimization projects of national support for multi energy complementarity,and propose a multi energy complementarity system structure that adapts to clean energy consumption,laying the foundation for the establishment and benefit evaluation of multi energy complementarity operation optimization models that adapt to clean energy consumption in the future.Secondly,a multi energy complementary system operation optimization model was established to adapt to clean energy consumption.The objective function is proposed to maximize the operating benefits of the system,minimize the energy rejection rate of clean energy and carbon dioxide emissions.Considering the system energy balance,energy transmission,unit output and other constraints,a multi energy complementary operation optimization model suitable for clean energy consumption is established.Based on the traditional particle swarm optimization algorithm,the particle swarm optimization algorithm is optimized by combining Latin hypercube sampling and fuzzy decision-making ideas,Propose an improved multi-objective optimization particle swarm optimization algorithm to lay the foundation for solving optimization examples of multi-energy complementary system operation in the following text.Then,a multi energy complementary benefit evaluation model adapted to clean energy consumption was constructed.In order to effectively evaluate the multi-dimensional comprehensive benefits of a multi energy complementary system adapted to clean energy consumption,a multi energy complementary evaluation index system adapted to clean energy consumption was constructed from four dimensions:economy,environment,technology,and society.Secondly,on the basis of indicator standardization and subjective and objective weighting,a multi energy complementary system benefit evaluation model based on multi-level fuzzy evaluation and cloud model evaluation methods was constructed,To provide decisionmaking support for the comprehensive benefit evaluation of a multi energy complementary system that adapts to the consumption of clean energy.Finally,an example analysis is conducted on a multi energy complementary system that adapts to clean energy consumption.On the basis of the multi energy complementary system built above to adapt to clean energy consumption,combined with the above operation optimization and benefit evaluation model,a multi energy complementary demonstration industrial base in Qinghai is selected as an example,and whether the electricity/gas conversion equipment and demand response mechanism participate in the coordinated operation of the multi energy complementary system is taken as the scenario setting variable for example analysis,At the same time,based on the data obtained from the optimized operation,the comprehensive benefits of the multi energy complementary system under different scenarios are further calculated and analyzed.The example verifies that the proposed multi energy complementary system adapted to clean energy consumption has a significant role in promoting clean energy consumption and utilization.It shows that the multi energy complementary system adapted to clean energy consumption has a significant role in promoting clean energy consumption and utilization,At the same time as reducing the waste rate of clean energy,it effectively improves the collaborative utilization efficiency of multiple energy complements in the park,reduces costs on the user side and system side,improves energy supply reliability and user satisfaction,and achieves multi-dimensional comprehensive benefits such as environmental,economic,and social benefits.
