电力转天然气（PtG）技术是一种用于可变发电高度渗透的电力系统变化管理的能量存储选项。本文以丹麦为例，研究了PtG机组对电力系统经济调度的影响。提出了一种基于直流最优潮流框架的PtG多周期调度模型。该模型已被用来研究PtG在一个简化的丹麦电力传输系统中的操作，涉及PtG的大小和位置在一年的时间内的一些情况。结果表明，PtG的利用将减少4.1%的总系统运行成本，并导致减少风力发电削减高达2%，以及在传输网络拥塞的时间步长的数量减少。将PtG分布在所研究的系统中的三个位置上将进一步减少风电削减。
The power-to-gas (PtG) technology is an energy storage option for variation management in power systems with high penetration of variable electricity generation. This paper investigates the effects of PtG units on the economic dispatch of power systems for the case of Denmark. The paper proposes a multi-period scheduling model for PtG based on a dc optimal power flow framework. The model has been used to study the operation of PtG in a simplified Danish power transmission system for a number of scenarios involving the sizes and locations of PtG over a period of one year. The results indicate that the utilization of PtG will reduce the total system operation cost by 4.1% and lead to a reduction in wind power curtailment of up to 2%, as well as a reduction in number of time steps with transmission network congestion. Distributing PtG over three locations in the system investigated will decrease the wind power curtailment even further.
