摘要:
      柔性负荷调度是优化负荷曲线、减少设备容量、促进可再生能源消纳的重要手段。考虑热网的传输延时性以及用户对温度感知的模糊性,建立热力柔性负荷模型,同时考虑可平移负荷、可转移负荷、可削减负荷3类电力柔性负荷,以包含投资、运行、补偿成本的系统总成本最低为目标函数,建立区域综合能源系统储电、储热设备优化配置模型,并采用LINGO商业软件进行仿真分析,得到各个设备的最佳出力以及储能设备的最优容量。算例结果表明,相比于未考虑电/热柔性负荷的场景,电/热柔性负荷的参与能够优化电/热负荷曲线,减少储能设备的容量,增强区域综合能源系统的灵活调节能力,降低能耗以及储能设备的投资费用,使系统的经济性达到最优。
Abstract:
      Flexible load scheduling is an important means to optimize load curve, reduce equipment capacity, and promote renewable energy accommodation. Taking transmission delay of heating network and ambiguity about temperature perception into account, a thermal flexible load model is established. Considering three types of electric flexible load including shiftable, transferable, curtailable loads, with the minimum total cost including investment, operation and compensation cost as the objective function, an optimal configuration model of electric/thermal energy storage for regional integrated energy system (RIES) is established. Moreover, a simulation program using a commercial software called LINGO is developed to obtain the optimal output of each device and optimal capacity of energy storage. Compared with the scenario where the electric/thermal flexible load is not considered, simulation results indicate that, the participation of the electric/thermal flexible load could optimize the electric/ thermal load curve, reduce the capacity of the energy storage device, enhance the flexible adjustment capability of RIES, reduce the energy consumption and investment cost of energy storage and achieve optimal economic operation of the system.
