On Economic Dispatch With Wind Power Generation And BESS Considering Carbon Emission Cost

With the development of the global economy and society,the core position of the energy strategy has gradually become prominent,and clean energy has become the key for mankind to solve resource,energy and environmental problems.Wind power is the main manifestation of clean energy,and certain difficulties and challenges have also been encountered in the dispatch process of wind power being continuously connected to the grid.Therefore,it is of great significance to study the wind-storage joint economic dispatch considering the cost of carbon emissions.Distributed power generation represented by wind power plays an important role in solving energy problems.This thesis first sorts out the related research on the joint economic dispatch of wind turbines connected to the power grid and traditional units.The existing research on battery energy storage system and carbon tax is analyzed.Aiming at the deficiencies of existing research,this thesis studies the economic dispatching problems of wind power and battery energy storage systems.Then the output characteristics of the wind turbine and the factors affecting the output of the wind turbine,the classification and characteristics of the energy storage system,and the charging and discharging principle of the battery energy storage system are analyzed.From the perspective of the combined wind storage system,the influence of economic dispatch is explained.Based on the two methods of emission pricing,the characteristics of the two methods are explained,and a wind-storage joint economic dispatch model with the smallest total cost is established,and the carbon emission tax is taken into consideration in parameters optimization in the objective function.In the constraints,linear and nonlinear constraints are considered,and the constraints of wind power,systems,units,battery energy storage and other equipment are comprehensively analyzed.The particle swarm algorithm is used to obtain initial boundary conditions,and then the quantum algorithm is used to search for the global optimal solution.Finally,the IEEE30-node system is used to simulate and analyze the model and algorithm.Combined with different wind power and energy storage scenarios,the rationality of the wind-storage joint economic dispatch model established in this thesis is verified.
