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，建立了热力柔性负荷模型。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 and curtailable loads

with the minimum total cost including investment

operation and compensation cost as the objective function

an optimal configuration model of power/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 power/thermal flexible load is not considered， simulation results indicate that the participation of the power/thermal flexible load can optimize the power/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 the optimal economic operation of the system.
