Abstract
Under regional coordinated development strategy, there is a pressing need to enhance existing time-of-use (TOU) tariffs formulation mechanism to address the issue of how to jointly optimize TOU tariffs for the provinces in a region. This paper proposes a TOU tariffs joint optimization mechanism. Firstly, a division method for regional agents is developed. In this method, all regional agents are divided into conventional agents (CAs) and region stability facilitation agents (RSFAs). When setting TOU tariffs, each CA focuses on the conditions of its province, while each RSFA will contemplate the conditions of both its province and region. Under a RSFAs selection strategy, all agent models will formulate TOU tariffs jointly, and constitute a joint optimization model. Secondly, the model will further constitute a non-cooperative game solved using diagonalization method and particle swarm optimization with linearly decreasing inertia weight (DM-IWPSO) algorithm. Moreover, multi-objective problems constituted by CA and RSFA models are transformed into single-objective problems by introducing two new cost indices. Finally, the proposed mechanism is tested in Beijing-Tianjin-Tangshan power grid. The results indicate that the proposed mechanism maybe more conducive to maintaining the stability of the regional power grid and more beneficial for the implementation of regional coordinated development strategy.

  • 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
