摘要

电转气技术(P2G)的出现让电力系统和天然气系统间的能量双向流动成为可能

促进了气-电网络的深度融合

也为解决间歇性可再生能源发电出力的波动性问题提供了新途径;P2G技术使天然气和电能间具有相互可替代性

使多能源市场的联系更加紧密

是未来多能源系统的重要支持技术。在此背景下

针对包括P2G的多能源系统的市场均衡问题

首先采用近年来发展起来的能源中心建模方法对集成了P2G设备、储气装置、燃气机组等多种能源转换装置的多能源系统进行建模。之后

在博弈论的框架下

研究了各个能源中心同时参与多个能源市场时的市场均衡问题

建立了确定市场均衡点的优化模型

并适于采用并行算法求解。最后

采用一个4节点能源中心测试系统和澳大利亚维多利亚州气电联合系统为例对所提出的模型与方法进行了仿真验证。

Abstract

The emergence and development of the power-to-gas (P2G) technique have made the bidirectional energy flow between power and natural gas systems possible. P2G represents a key technique in the emerging energy internet

and promotes the integration of multi-energy systems. By transforming electricity to gas

existing gas storage facilities can be used to mitigate the volatility of renewable energy generation. The modeling of future complex multi-energy systems with P2G functions is presented based on the “energy hub” framework

and a coordinated optimization model presented. A game-theory-based method is next proposed to attain market equilibrium in a multi-energy system. A 4-bus sample multi-energy system and a simplified Victoria gas-electricity combined network system in Australia are adopted for demonstrating the effectiveness of the presented optimization model and solving algorithm.
