摘要
为了节能减排和碳捕集电厂不足情况下碳减排指标的完成,在碳减排日指标约束下,提出一种碳捕集调度策略以实现厂内减排和厂网协调减排。厂内减排引入碳捕集装置的启停次数,以煤耗最小为目标实现机组的组合。厂网协调减排时,通过多代理解决各时段的机组优化问题和机组爬坡问题,在综合考虑煤耗及网损的基础上,使碳捕集电厂多发电并进行碳捕集以实现CO2减排的目的。仿真结果表明,在不同指标的约束下,厂内减排和厂网协调减排能有效地实现碳减排任务。
To develop energy-saving and emission- reducing and achieve the carbon emission reduction target in the case of insufficient carbon capture plants, a dispatch strategy for carbon capture was proposed to realize carbon emission reduction of power plants and plant-grid coordination under carbon emission reduction day index constraints. In carbon emission reduction of power plants, the start-stop frequency of carbon capture device was considered and plant units were optimized to minimize coal consumption. In carbon emission reduction of plant-grid coordination, unit optimization of each period and creep speed of units was solved by multi-agent system. Based on an overall consideration of coal consumption and network loss, units bearing carbon-capture device was made to output more active power and their carbon was captured so as to achieve the objective of C02 capturing. The simulation results show that carbon emission reduction of power plants and plant-grid coordination can effectively realize the task of carbon emission reduction.
