Low Carbon Economic Dispatch Of Power System Based On Multi-round First-order Sealed Auction Carbon Trading Mechanism

The power industry has great potential in reducing CO2 emissions,and has a large space to be optimized.Carbon trading mechanism speeds up the pace of emission reduction in the power industry,and promotes the economic development of the power system in the direction of low carbon.In addition,wind power as a clean energy,reducing greenhouse gas emissions,to promote the development of low-carbon electricity industry.However,due to the randomness of wind power,and the wind power output is often associated with the actual wind power output error,therefore,the dynamic scheduling of the system has brought challenges.In this paper,the CETM(Carbon emissions trading mechanism),the low carbon economic dispatch problem of wind power system is studied.Firstly,several classical economic dispatch models of power system are introduced,and the uncertainty of wind power output is solved by stochastic programming.This paper analyzes the initial allocation scheme of three kinds of carbon emission rights in the carbon trading mechanism,and verifies the superiority of the proposed allocation scheme through simulation,and analyzes the three main carbon emission rights initial allocation methods.Secondly,a multi-objective scheduling model is proposed for the low carbon economic dispatch of wind power system based on multi-round first-order sealed auction.The auction mechanism of carbon emissions trading was improved and established a new target of low carbon scheduling auction under the carbon emissions trading mechanism,and flexible load cost in economic dispatch target,economic dispatch target is established and flexible load.By using the simulation of hybrid particle swarm optimization algorithm,the simulation results show the superiority of the proposed model.This paper studies the influence of the flexible load and the first order sealed auction on the optimal scheduling.The simulation results show that the new low-carbon economy model has the advantages of low carbon economy and low cost.Finally,put forward in two to promote low carbon economic dispatch model for interaction of emission reduction trading mode,in which the objective function contains isthe general operation of the unit with the lowest cost of economic dispatch in power,and to minimize the cost of carbon emissions trading rights and joint mechanism under low carbon scheduling objectives,studied the effect of the interaction the two way to reduce the carbon price output program for each unit.The algorithm is used to optimize the solution of the objective function.The simulation results show that the model can reduce the carbon emissions.
