Integrated energy micro⁃grid optimization operation with environmental cost and multiple kinds of energy storage

为考虑冷热电联供型综合能源微网运行时产生的环境成本和分析储能装置容量对系统运行成本的影响,建立了包含环境成本和储能装置的冷热电联供型综合能源微网优化运行模型。以系统总成本最小为目标,采用混合整数规划方法在Cplex中求解,并与相对应传统分供系统运行成本对比,验证了模型的有效性。分析了冷热电联供型综合能源系统在不同类型电价模式下的运行成本以及储能装置不同容量对系统运行成本的影响,得出了系统在实时电价模式下运行成本最小和系统运行成本随储能装置容量的增大先增加后降低的结论。

In order to consider the environmental cost generat-ed by the operation of the combined cooling,heating and power inte-grated energy micro-grid and analyze the impact of the capacity ofthe energy storage device on the operating cost of the system,an opti-mized operation model of the combined cooling,heating and powerintegrated energy micro-grid including environmental costs and ener-gy storage devices is established.With the minimum total systemcost as the goal,the mixed integer programming method is used tosolve the problem in Cplex,and the operating cost of the correspond-ing traditional distribution system is compared to verify the validityof the model.The operating costs of the combined cooling,heatingand power system under different electricity price modes and the im-pact of different capacities of energy storage devices on the operatingcosts of the system are analyzed.It's concluded that the operatingcost of system is the smallest under the real-time electricity pricemode,and the operating cost of the system increases frist and then de-creases with the increase of the capacity of the energy storage device.
