【摘要】 为协调新能源与火电协调配合过程中的经济性和灵活性问题。提出一种电源经济灵活协同优化出力策略。为约束碳排放和碳交易成本，引入碳交易机制对系统中的碳排放配额及实际碳排放进行建模，将碳排放转化为有经济价值的调度资源。针对新能源高占比系统灵活性不足问题，进行系统灵活性供需能力分析并建立电源经济-灵活协同优化出力模型，然后用轮盘赌选择和跳跃基因改进NSGA-Ⅱ算法提高模型求解效率。最后以改进的IEEE30节点为算例进行仿真分析并设置对比，结果表明模型的有效性。更多还原

【Abstract】 With the increase in the proportion of new energy in the power system, the contradiction between the comprehensive economic benefits of the system and the lack of flexibility in output regulation caused by fluctuations in new energy has intensified. To this end, this paper proposes a power economy flexible synergistic optimization output strategy. In order to constrain carbon emissions and carbon trading costs, a carbon trading mechanism is introduced to model carbon emissions quotas and actual carbon emissions in the system, and convert carbon emissions into dispatch resources with economic value. Aiming at the lack of flexibility of the high proportion of new energy system, the system flexibility supply and demand capability is analyzed and a power economy flexible collaborative optimal scheduling model is established. Then, the NSGA Ⅱ algorithm is improved by roulette selection and jumping genes to improve the model solving efficiency. Finally, the improved IEEE30 node is taken as an example for simulation analysis and comparison. The results show that the model proposed in this paper is effective.更多还原
