基于层次分析法与熵权法相结合的配电网节能改造技术经济评估
Inner Mongolia Electric Power（2021）
Abstract
综合考虑配电网节能指标及能耗影响因素,建立了配电网一次设备节能改造技术经济评估体系,涵盖了供电能力、技术装备、无功补偿措施以及新节能技术等评价指标.基于层次分析法和熵值法计算了指标体系各单项指标的权重,并结合单项指标状态值,得到配电网综合能效分值;基于全寿命周期成本,优化了配电线路、变压器,增设了无功补偿装置,并建立新型节能设备三方面的全寿命周期成本效益模型.结合成本收益分析的方法,对配电网节能改造方案进行经济性评价.最后,以某地区实际配电网为实例,验证了该指标体系和评估方法及经济性评价方法的有效性与实用性.

- 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
