Abstract

Due to the growing trend of load and the high cost of electric energy production, and the limitation in the installation of new power plant units, planning and minimizing the cost of energy generation for active units in the power plants is necessary. The purpose of optimal power flow is to allocate the optimal contribution of the power plants, provide the required power of the network, and minimize the cost of power generation. In this article, the shuffled frog leaping algorithm (SFLA) is employed for the planning of the electrical energy by optimal power flow for minimizing costs and the emission pollution in the power plants. A quadratic objective function is expressed in terms of the generation of units in which constraints are modeled as linear equal and unequal equations. The proposed method is applied to a system of IEEE -30 bus test system. The obtained results show the ability of the proposed algorithm in the optimization of objective functions. Also, the results obtained from this algorithm have been compared with the results from other evolutionary algorithm methods.

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
