Research On Capacity Optimization Configuration Of Expressway Exchange Power Station Under Low Carbon Background

With the shortage of global energy,climate warming and the deterioration of ecological environment,the impact of the deterioration of the ecological environment on human beings is becoming more and more prominent.Electric vehicle has great advantages in energy saving and emission reduction.The development of electric vehicle is an important way to alleviate environmental pressure and ensure energy security.Therefore,a lot of research has been done on electric vehicle technology.Highway is an important transportation channel for the development of national economy,and the application of electric vehicle to expressway is a trend in the future,but the highway has a long distance.Once on the highway,electric vehicles may not have enough electricity to reach their destination,so that their operation in the highway is greatly restricted.Therefore,the construction of energy capture facilities on the highway is a necessar y condition for the development of electric vehicles.For electric vehicles,the capacity configuration of power station is the basic problem of the construction of power station.In this paper,the optimal configuration of the capacity of the switching po wer station and the participation of the switching power station in the overall optimal operation of the power network are studied.In view of the above problems,this paper studies the capacity optimization of the switching power station based on the expressway exchange power station.At the same time,the flexible carbon capture unit and wind power are added to the model to study the influence of the model on the capacity of the switching power station.The main research contents are as follows:Firstly,the characteristics of expressway exchange power station,carbon capture power plant and wind power are analyzed.In a low-carbon context,carbon capture plants can reduce carbon emissions,rapid peak shaving and wind power volatility by using the charge-discharge controllable characteristics of the switching power station.It is possible to study the optimal configuration of the capacity of the expressway exchange power station by organic combination of the three.Secondly,the optimization model of capacity allocation of expressway changing power station is established.The models of switching power station,carbon capture power plant and wind power are studied.The objective functions are the fuel cost,carbon emission cost,wind power acceptance cost and battery loss cost of thermal power units.The optimal configuration model of power station capacity is constructed,and the model is modeled and solved by lingo.Finally,the optimal configuration of the capacity of the expressway power station under various scenarios is simulated and analyzed.The scenarios include the case of switching power station and conventional thermal power plant,the combination of switching power station and flexible carbon capture power plant,the combination of exchange power station and wind power,and the case of changing power station,flexible carbon capture power plant and wind power plant.The optimal configuration of power station capacity under different scenarios is determined,and the influence of different factors on the capacity of the power station under different scenarios is studied.
