考虑电热气耦合的综合能源系统规划方法

Planning Method for Integrated Energy System with the Consideration of Coupling among Power,Heat,and Gas

为了确定综合能源系统中能源设备类型和容量的最优配置,本文提出了一种考虑电、热、气耦合的综合能源系统(IES)设备选型及容量规划方法。首先从可选设备的类型和输入能源的形式出发,建立IES的基本架构。在此基础上,针对设备选型及容量规划问题,建立了以年综合费用最小为目标函数的优化模型,采用混合整数线性规划算法,对设备类型和容量同时进行优化。最后以某IES园区为实例,给出了不同场景下的规划方案,并验证了所提方法的有效性。

To determine the optimal configuration of types and capacities for energy equipment in an integrated energy system ( IES ), a method of equipment selection and capacity planning for the IES is presented with the consideration of the coupling among power , heat , and gas. First , starting from the types of optional equipment and the form of input en-ergy , the basic framework of the IES is established. On this basis , aiming at the problems in equipment selection and capacity planning , an optimization model is set up with the minimum annual comprehensive cost as the objective func-tion. The mixed integer linear programming ( MILP ) algorithm is adopted to optimize the types and capacities of the equipment simultaneously. Finally , an IES park is taken as an example , and the planning schemes under different sce-narios are given. Moreover , the effectiveness of the proposed method is verified.
