摘 要:綜合能源系統由于其能源的梯級利用可以促進可再生能源的消納,而電轉氣(P2G)設備的出現可以很大程度上促進風電消納,在能源中心概念的基礎上建立了包含電轉氣(P2G)設備的綜合能源系統模型,以系統運行成本最低作為目標進行調度研究,在約束條件中考慮了系統內部的功率約束、能源轉換設備以及儲能設備的運行約束,通過算例在MATLAB平臺進行仿真驗證,構建了兩個不同的場景,分別考慮在加入電轉氣(P2G)設備和不加入情況下系統的風電消納能力,結果表明電轉氣(P2G)設備的加入促進了系統對風電的消納。
關鍵詞:綜合能源系統;電轉氣;能源中心;經濟調度

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
