摘要/Abstract

摘要： 基于碳捕集设备与综合能源系统的结合能够有效提高系统风电消纳能力。提出了一种含电转气、燃气轮机、碳捕集电厂、风电场联合运行的低碳经济调度模型,并引入碳交易机制,以系统综合经济成本最低为目标函数,以电转气功率、燃气轮机有功出力、机组有功出力、碳捕集率为决策变量,考虑电力网络与天然气网络相关约束、电气平衡及机组爬坡约束等。通过算例仿真,分析比较了系统CO₂排放量、系统综合经济成本以及弃风量,验证了所提模型能够有效提高风电消纳能力,具有降低CO₂排放量以及综合经济成本的作用。最后,分析了碳交易价格对系统CO₂排放和运行的影响。

Abstract: The combination of carbon capture equipment and comprehensive energy system can effectively improve the wind power consumption capacity of the system.A low-carbon economic dispatch model including electricity to gas,gas turbine,carbon capture power plant and wind farm combined operation was proposed,and the carbon trading mechanism was introduced.The objective function was the lowest comprehensive economic cost of the system.The decision variables are electricity to gas power,active power of gas turbine,active power of unit and carbon capture rate.The correlation constraint between power network and natural gas network is considered,including electric-gas balance and unit climbing constraints,etc.Through the example simulation,the carbon dioxide emission,comprehensive economic cost and abandoned air volume of the system were analyzed and compared to verify that the proposed model can effectively improve the capacity of wind power consumption and reduce the carbon dioxide emission and comprehensive economic cost.Finally,the impact of carbon trading price on carbon dioxide emission and operation of the system was analyzed.

Key words: carbon capture, integrated energy source system, electric conversion gas, low carbon economic dispatching, wind power absorption.
