Research On Optimal Model Of Generation Rights Trade Considering Carnon Trading And Loss Cost

While the scale of the power industry is expanding rapidly,the international community is increasingly calling for reducing greenhouse gas emissions to slow down global warming.As the country with the largest carbon emissions,it is necessary to contribute to reducing carbon emissions.At present,many scholars have been using the two mechanisms of electricity and carbon market to accelerate the development of the pow er industry towards cleaner,efficient and low-emissions.In order to further promote the implementation of green and low-carbon development policies in China's power industry,it is necesssary to conduct in-depth research on the two market mechanisms mentioned above.Combined with the current situation of China s thermal pow er installed capacity and power generation,this paper studies the generation rights trade which is explicitly included in the new electricity market reform,and its maximum social benefit model and network loss allocation.With the successfu l operation of the seven carbon trading pilots,the establishmen t of the national carbon market and the first inclusion in the power industry,the development of the carbon emission trading mechanism is of great significance for achieving the low carbon sustainable development of the power industry.Therefore,based on the connotation of the transaction and the commonly used carbon emission trading mechanism,the traditional generation rights traqde model is improved by introducing incremental network loss cost and carbon trading income in the objective function of the maximum social surplus.in order to achieve energy saving,emission reduction and to ensure the safe and economic operation of power system.Firstly,on the basis of high-low matching,two kinds of the maximization social surplus models have been compared,which take total quantity and unit quantity of electricity as decision variable separately.Then,based on the traditional generation rights trade model with maximum transaction power,this paper combines the CO2 emission reduction achieved after generation rights trade with the allocation of initial carbon emission quota,establishes a single-objective model of the optimal combination of generation rights trade and carbon trading benefit by introducing the carbon trading mechanism.And the actual generation rights trade data verify the feasibility of the proposed model.Secondly,since the generation rights trade will affect the system power flow distribution and active losses,this paper uses the marginal loss coefficient method to calculate and share the incremental network loss of the system before and after transaction to provide suggestions for compensating the loss of the grid company.And the rationality and effectiveness of the proposed algorithm are verified by using the IEEE 14-node system.Finally,a day-ahead model for generation rights trade considering carbon market revenue and incremental network loss cost has been established.The simulation of the IEEE 39-node system shows that the introduction of the carbon trading in generation rights trade model can effectively increase the transaction quantity,while reducing the incremental network losses caused by generation rights trade,further realizing energy saving and emission reduction of power system and promoting the consumption of clean energy.
