Research On Operation Decision Of Thermal Power Units With Both Electricity Spot Trading And Carbon Emissions Trading

In the context of energy revolution and the gradual development of the goal of "carbon peak,carbon neutrality",the implementation of low-carbon economy as an internal requirement of sustainable development,is also one of the ways to achieve leapfrog development.Changing the way of energy use is the key to low-carbon development,that is,replacing traditional energy with new energy.However,coal has always been our main energy and basic industry,from a long time in the future,the energy development pattern of our country will still be mainly coal.Fire power industry is the main industry that uses coal,it is the main power source in our country,and also the main part of carbon dioxide emission in all walks of life.With the official launch and gradual development of the national carbon emission trading market,the power industry is the first to be included in it,and thermal power units are facing great pressure to reduce emissions.Therefore,it is of great significance to study the optimal decision-making and lowcarbon development path of thermal power units when they participate in power trading and carbon emission rights trading.This paper first introduces the research background and research significance of the paper,summarizes the research status at home and abroad,and points out the research content,research methods and innovation points of this paper.Then it systematically analyzes the status quo of thermal power industry under the energy revolution and electricity marketization reform,and introduces the power production,installed capacity and installed capacity structure of the five power generation groups in recent years.Then according to the facilities and equipment,human resources,operating costs,low carbon development management,carbon emission intensity,low carbon technology research and development of these six aspects of the thermal power unit status is analyzed.Then,the relevant theoretical basis of the national carbon emission rights trading market and carbon capture power plants is introduced,which lays a theoretical foundation for the following construction of several thermal power unit cost-benefit models,calculation example analysis and operational decision-making suggestions for thermal power units.Secondly,this paper first establishes the cost-benefit model of conventional thermal power units.Then combined with the current situation of electricity spot market,a cost-benefit model of thermal power units participating in electricity spot trading is established considering electricity spot trading.Then,considering the scenario of thermal power units participating in the carbon market for carbon emission rights trading,combined with the first two models established in this paper,a cost-benefit model of thermal power units is built that takes into account electricity spot trading and carbon emissions trading.In this model,post-combustion carbon capture equipment is added to reduce the carbon emissions of thermal power units.Finally,combined with the current actual situation,this paper takes the actual data of a northeast region as an example to conduct simulation analysis and comparison of the three models built in turn.Then,aiming at the scenario of carbon quota reduction of thermal power units leading to the increase of carbon emission right price in the carbon market,the cost and benefit model of thermal power units with additional carbon capture equipment,which takes into account both power trading and carbon trading,is simulated and analyzed with examples in order to put forward corresponding operational recommendations for thermal power units under different scenarios.
