    摘 要:综合能源系统由于其能源的梯级利用可以促进可再生能源的消纳,而电转气(P2G)设备的出现可以很大程度上促进风电消纳,在能源中心概念的基础上建立了包含电转气(P2G)设备的综合能源系统模型,以系统运行成本最低作为目标进行调度研究,在约束条件中考虑了系统内部的功率约束、能源转换设备以及储能设备的运行约束,通过算例在MATLAB平台进行仿真验证,构建了两个不同的场景,分别考虑在加入电转气(P2G)设备和不加入情况下系统的风电消纳能力,结果表明电转气(P2G)设备的加入促进了系统对风电的消纳。

    Abstract: Integrated energy systems can promote the consumption of renewable energy due to the cascade utilization of energy. The emergence of power to gas (P2G) equipment can greatly promote wind power consumption. Based on the concept of energy center, it has established electrical transmission. The integrated energy system model of power to gas (P2G) equipment is based on the lowest operating cost of the system as the target for scheduling research. In the constraints, the power constraints, energy conversion equipment, and energy storage equipment's operating constraints are considered. Through simulation examples on the MATLAB platform, two different scenarios are constructed, which are considered the wind power capacity of the system with and without P2G equipment. The results show that the addition of electricity to gas (P2G) equipment promotes the system's dissipation of wind power.
    Key words: integrated energy system; power to gas; energy hub; economic dispatch
