考虑碳捕集电厂削峰填谷特性的低碳经济调度

Low-Carbon Economic Dispatch Considering Peak Shaving and Valley Filling Characteristics of Carbon Capture Power Plants

针对传统固定式的高捕集能耗和风光反调峰问题,储液式碳捕集电厂制定新的调度策略来提高系统低碳经济特性。首先,对比固定式和储液式的运行机理,针对负荷峰谷时段各调度资源特性挖掘储液式存在的削峰填谷特性;然后,构建以兼顾运行成本、弃风量和碳排放的系统综合成本最低为目标的含溶液存储模型与碳交易机制的低碳经济调度模型,采用改进的粒子群优化算法对模型求解;最后,通过仿真算例对比,含储液式碳捕集电厂的系统碳排放量降低了3.8%,综合成本降低了5.9%,同时弃风成本降低了65.4%,验证了所提调度策略的优越性。

In the context of the current large-scale thermal power generation,carbon capture power plants have become one of the best choices to quickly achieve the"dual carbon"goal.Due to the high energy consumption of traditional fixed type capture and the problem of wind solar anti-peak shaving,the introduction of liquid storage carbon capture power plants is considered to develop a new dispatch strategy to improve the low-carbon economic characteristics of the system.First,the operation mechanism of the fixed type and the liquid storage type are compared,and the peak shaving and valley filling characteristics of the liquid storage type are explored according to the characteristics of each dispatching resource during the load peak and valley period;then,a comprehensive system that takes into account operating costs,abandoned air volume and carbon emissions is constructed.Finally,through the simulation example comparison,the system carbon emissions of the reservoir containing carbon capture power plant are reduced by 3.8%,the comprehensive cost is reduced by 5.9%,and the curtailment cost is reduced by 65.4%,which verifies the superiority of the proposed scheduling strategy.
