摘要 针对含储能的综合能源系统优化调度问题,从电/热储能互补协调的角度提出电-热综合能源系统优化调度方法。首先考虑热网储热特性及供能网络电压、温度等节点状态约束,建立综合能源系统模型;然后分析新能源所接的电储能、热电联产所接的热储能、电制热设备所接的热储能三类储能在消纳新能源弃电和电负荷削峰场景下的互补协调关系;在此基础上,建立综合能源系统优化调度模型,通过简化热网模型、引入0-1变量、大M法等方法处理模型中的非线性项,并利用GAMS进行建模求解;最后以IEEE 33节点配电网与45节点热网耦合系统为例进行分析。结果表明,电储能和热储能协调运行能有效地消纳新能源弃电量和削减电负荷高峰,实现了多能存储上的优势互补。

Abstract:Aiming at the optimal scheduling problem of integrated energy system with energy storage, the optimal scheduling method of integrated energy system is proposed from the perspective of complementary coordination of electricity and heat energy storage. Considering the heat storage characteristics of the heat network and the node state constraints such as the voltage and temperature of the energy supply network, a integrated energy system model is established; the complementary coordination relationship of three types of energy storage, i.e. the electric energy storage connected to the new energy, the thermal energy storage connected to the cogeneration, and the thermal energy storage connected to the electric heating equipment, is analyzed under the scenarios of new energy consumption and peak load reduction; and on this basis, a optimal scheduling model is established. The optimal scheduling model of the system, through simplifying the heat network model, introducing 0-1 variable, big M method and other methods to deal with the nonlinear terms in the model, and using GAMS to model and solve. Finally, taking IEEE 33 node distribution network and 45 node heat network coupling system as an example to analyze. The results show that the coordinated operation of electric energy storage and thermal energy storage can effectively absorb the waste power of new energy and reduce the peak load of electric power, and realize the complementary advantages of multi energy storage.
