Abstract
针对综合能源系统中多种能源耦合以及不同能源的异质性,首先,利用流量分段法构建了更为精确的近似供热管道模型,并结合建筑的储热特性,共同构建了考虑2类热惯性的热力系统模型;其次,研究热能在调度过程中的特点,对2类不确定量进行描述;然后,利用信息间隙决策理论(information?gap?decision theory,IGDT),建立了鲁棒优化模型和机会优化模型,并引入非支配遗传算法(NSGA-II)对多目标模型进行求解;最后用44节点供热网络系统进行仿真,结果表明:该方法可有效量化热媒流率和热损耗的不确定性对调度运行的影响,提升了系统运行的经济性.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
