针对风电-P2G与燃气采暖多能耦合系统(WP-P2G&GHMECS)的规划问题,提出一种在全寿命周期内的多能耦合系统规划分析方法。首先,阐述以P2G为媒介的多能耦合系统集成方案;其次,以多能耦合系统全寿命周期净利润为目标,以风电最大限度消纳与WP-P2G&GHMECS稳定运行为约束条件,建立系统设备选型模型与全寿命周期经济规划模型,以多能耦合系统的资金回收期和全寿命周期净利润为指标对系统进行经济性评估;最后,以某风电场与P2G厂站为背景对文中所建立的经济规划模型进行仿真计算,并分析其在不同风电并网比例和非电能形态消纳比例下系统经济性的变化规律。

Aiming at the planning problem about wind power-P2G and gas heating multi-energy coupling system(WPP2G&GHMECS),this paper put forward a method about a multi-energy coupling system planning analysis method in the full life cycle.Firstly,state the integration scheme of multi-energy coupling system based on P2G.Secondly,the net profit of the multi-energy coupling system is taken as the goal,the system equipment selection model and the life cycle economic planning model are established based on the maximum consumption of wind power and the stable operation of WP-P2G&GHMECS.Taking the multi-energy coupling system’s capital recovery period and full life cycle net profit as indicators,economic evaluation of the system.Finally,the economic planning model established in this paper is simulated with a wind farm and P2G station as the background.Finally,the economic planning model established in this paper is simulated with a wind farm and P2G station as the background.The changing rule of system economics under the condition of different wind power grid-connected ratios and non-electrical energy consumption ratios are further analyzed.
