Research On Low Carbon Power Dispatching Technology Of Regional Power Grid Considering Carbon Trading

In recent years,due to the dual pressure of environmental degradation and energy shortage,as a flexible market mechanism,carbon emissions trading mechanism plays an important role in reducing carbon dioxide emissions and reducing carbon dioxide emission reduction costs in the implementation of energy saving and emission reduction.Under the background of low carbon,the power industry,as the largest source of carbon emissions,is responsible for the energy saving and emission reduction.Therefore,this paper analyzes the optimal operation of regional power grid under the condition of carbon trading,in order to achieve the goal of energy saving and emission reduction.This paper first discusses the research status of the low carbon power dispatching,the carbon emission trading market and the electricity market,and discusses the relationship between the three aspects,and analyzes the carbon emissions trading.According to the calculation criteria of the baseline emission factor of china regional power grid,the annual carbon emission quota of regional power grid can be calculated.In this paper,the multi time scale coordinated operation of low carbon power dispatching in regional power grid considering carbon trading is studied,including the annual,monthly,daily and real-time low carbon power scheduling,decomposition and coordination correction.Considering the constraints of power balance constraints,power capacity constraints,carbon quota constraints,power flow constraints,and so on,coordination and optimization models of regional power grid low carbon scheduling are established.The effects of different factors such as carbon quota constraint and new energy generation on power grid operation are analyzed in comparison with the results of different scenarios.Then considering that in the carbon trading market,generation companies are faced with carbon quota constraints,and the volatility of carbon trading prices will bring risks to generation companies.By quantifying the carbon trading price fluctuation risk,considering the carbon quota restriction,power balance constraints,power capacity constraints,and other constraints,a bidding optimization model of generation companies considering carbon trading risk is established,and the impact of carbon trading on bidding strategies of generation companies is analyzed through examples,which provides references for generation companies to participate in carbon trading and avoid risks.Finally,in view of the above two aspects about low carbon power scheduling and bidding strategy research,the application research based on the data of Gongqingcheng power grid is carried out.
