含电动汽车的区域综合能源系统日前调度优化

Day － ahead Scheduling Optimization of Ｒegional Integrated Energy System Including Electric Vehicles

摘要:

区域综合能源系统是实现能源转型和解决环境问题的基础。随着中国电动汽车的大力发展，电动汽车作为 园区内灵活可调度资源，具备调峰和促进清洁能源消纳等作用。由此，建立一种包含电动汽车和分布式电源的区域 综合能源系统日前调度模型。首先，分析了区域综合能源系统中多种能量流动关系; 其次，对不同能源转换设备和电 动汽车独立建模的基础上，抽象出以园区日前综合经济效益最大化为目标函数的数学模型; 最后，在算例系统中分析 了含电动汽车参与区域综合能源系统日前调度的经济效益。

Abstract:

Ｒegional integrated energy system is the base of energy transformation and solving environmental problem． With the rapid development of electric vehicles in China，electric vehicles，as flexible and dispatchable resources in parks，play a role in peak regulation and promoting clean energy consumption． Therefore，a day － ahead scheduling model of regional integrated energy system including electric vehicles and distributed power supply is established． Firstly，the relationship of energy flow in regional comprehensive energy system is analyzed． Secondly，on the basis of independent modeling of different energy conversion equipment and electric vehicles，the mathematical model is abstracted taking the day － ahead comprehensive economic benefits maximization as objective function． Finally，the economic benefits of electric vehicles participating in day － ahead dispatching of regional integrated energy system are analyzed in the example system．
