Flexible Optimal Scheduling of Transportation Energy Self-consumption System for Highway Service Area Based on Load Classification and Degradation Costs of Storage Batteries
For the optimal operation of the transportation energy self-consumption system in highway service areas,a transportation energy self-consumption system optimal scheduling model with careful consideration of load classi-fication and energy storage degradation cost is proposed.First,the system load is graded according to the load classi-fication principle;the influencing factors of the life degradation of storage batteries are analyzed,and the whole-life storage degradation costs are modeled;a comprehensive cost function including the system power purchase costs,photovoltaic operation,and maintenance costs,storage batteries operation costs,load scheduling compensation costs,carbon trading costs,and storage degradation costs is formed,and the minimum of which is used as the objec-tive function,and based on the controllable flexible characteristics of the classification loads to establish its flexiable optimal scheduling model with relevant constraints.Finally,a multi-scenario simulation is conducted to compare and analyze the traffic energy self-consideration system for the Xinjiang Kelameili highway service area,considering the storage degradation costs and the controllable load classification factors.The results show that the proposed optimization model can effectively alleviate the power consumption pressure of the microgrid system in the highway service area and improve the service life of the energy storage battery;the peak-to-valley load differ-ence of the system can be reduced by 17.11％through the flexible regulation of the controllable load classification,and the total cost of the system can be reduced by 7.67％compared with the total cost of the nominal system.
