摘要:
      随着新能源装机比例的不断提升,燃气轮机平抑新能源波动性作用越发凸显,由此带来供电供气的一系列问题,越来越需要将电网和气网协同考虑。电转气技术将原来单向耦合的气-电混合系统转换为双向耦合。对涉及的天然气系统建模的普遍性、共通性问题进行了阐述,着重介绍了电力系统和天然气系统的协同优化研究,主要包括仅依靠燃气轮机作为能源接口的双网单向耦合系统研究进展和包含电转气的双网双向耦合优化研究情况。此外,对含电转气装置的电网和天然气网络耦合系统在国内外的实际工程应用情况进行概述,最后对今后双网耦合系统需要深入研究的问题进行了初步展望。
Abstract:
      With the continuous increase in the proportion of new energy installed capacity, the role of gas turbines to stabilize the volatility of new energy sources is becoming more and more prominent. Those bring some problems to the power and natural gas supply, and a growing need to consider the power and natural gas network collaboratively. Power-to-gas(P2G)technology converts the original unidirectional gas-electric hybrid system into two-way coupling. The universal problems involved in the modeling of natural gas system are illustrated. The collaborative optimization research between the power and natural gas system is introduced emphatically, which mainly includes one-way coupled system only relying on gas turbine as an energy interface and two-way coupled system after adding P2G devices. Besides, the practical engineering application at home and abroad of the power grid and natural gas coupled system including P2G devices is summarized. Finally the problems in the power and natural gas network coupled system that require further study are initially prospected.
