Study on Wind Power Consumption in an Electric-gas Integrated Energy System Considering P2G Technology

伴随着风电的大规模开发,无法消纳全部的风电产生了弃风现象,为提高风电利用率,提出一种利用考虑电转气技术的电-气综合能源系统对风电进行消纳。首先对电-气综合能源系统进行建模,建立其中主要设备的数学模型,利用粒子群算法对是否考虑电转气技术,是否考虑碳交易机制两种情况下综合能源系统中各主要设备的运行状况进行优化调度,并对系统中各个成本进行计算。研究表明,电转气技术的加入有效提高了电-气综合能源系统消纳风电的能力,并且同时考虑碳交易机制可以降低系统总体成本,有利于电转气技术的推广。

With the large-scale development of wind power,the phenomenon of abandoning wind power has occurred in the wind power which cannot absorb all the wind power.In order to improve the utilization rate of wind power,an electric-gas integrated energy system considering the electric-gas technology is proposed to consume wind power.First comprehensive energy to electricity,gas system modeling,to establish the mathematical model of the main equipment,using particle swarm optimization(pso)algorithm to consider DianZhuan gas technology,whether the carbon trading mechanisms in both cases the integrated energy system operational status of each main equipment in the optimal operation,and the various cost calculation in the system.The research shows that the addition of electricity to gas technology can effectively improve the capacity of electricity to gas integrated energy system to absorb wind power,and considering the carbon trading mechanism can reduce the overall cost of the system,which is conducive to the promotion of electricity to gas technology.
