电转气消纳新能源与碳捕集电厂碳利用的协调优化
|
摘要
电转气技术作为一种新型能源转换和储存方式为可再生能源消纳提供了新的途径,电转气技术生成甲烷所需的CO_2可高效经济地取自碳捕集机组的捕集碳量。提出将电转气-碳捕集电厂作为整体系统,建立电转气-碳捕集电厂协调优化模型,以碳成本、燃料成本、弃风成本、电转气成本为目标,以碳捕集率、碳捕集电厂有功出力、电转气功率为决策变量。仿真结果表明,电转气-碳捕集电厂提高了风电消纳能力,减少了碳排放,提升了碳利用水平,降低了电转气运行成本。
The power-to-gas technology,as a new type of energy conversion and storage,provides a new way for renewable energy accommodation,and its required CO_2 for generating methane can be efficiently and economically got from the carbon collection amount of carbon capture units. The power-to-gas-carbon capture power plant is taken as a whole system,and its coordinated optimization model is built,which takes the carbon cost,fuel cost,abandoned wind cost and power-to-gas cost as the objectives,and the carbon capture rate,active power output of carbon capture power plant and power-to-gas active power as the decision variables. Simulative results show that,the power-to-gascarbon capture power plant improves the wind power accommodation ability,reduces the carbon emission,improves the carbon utilization level,and reduces the power-to-gas operation cost.
