| In view of the current problem of serious wind abandonment in wind farms and huge maintenance of wind turbines,this paper proposes to build a power supply mode of “abandoned air volume + energy storage compensation power = tower elevator power consumption”.An economic model for optimal power dispatching of tower elevators based on minimum abandoned air volume.Firstly,the difference between the historical theoretical output data and the historical actual power data is taken as the historical abandoned wind volume.Based on this,a short-term abandoned wind power forecasting model based on CS-BP is established.Secondly,the expert experience survey method is used to explore the relationship between the number of tower elevator operations and the maintenance and repair time,and determine the daily power consumption of the tower elevator.The adjustment and maintenance plan is aimed at economic optimization,so the construction includes energy storage costs.The objective function of related indicators such as wind power purchase cost,energy storage compensation for thermal power discharge and environmental treatment cost,and the improved particle swarm optimization algorithm are proposed to solve the problem of optimal optimization of tower elevator power supply.The feasibility of the optimal economic model of tower elevator power supply considering the minimum abandoned air volume is verified by a case study,which opens up a new way for abandoning wind consumption. |
