To solve the problem of missing values in dispatching data in power system, so as to improve the security and stability of power system. This article proposes a missing sequence interpolation algorithm for power grid dispatch data based on multi-source data fusion. Firstly, preprocess the multi-source power grid dispatch data, including data normalization, data serialization, etc. Then, construct an LSTM long-term and short-term memory network model, and train the model using existing data to learn the features and patterns in the original data. Next, tensor PARAFAC decomposition is implemented through first-order partial derivatives to interpolate sequence data containing missing values. Finally, the effectiveness of the evaluation algorithm is verified through experiments. The experimental results show that the algorithm proposed in this paper has high interpolation accuracy and real-time performance, and can effectively interpolate missing values in power grid dispatch data.
With the development and progress of electric power communication technology in China, it gradually covers and improves the diversified and personalized needs of users. Different from the traditional network construction, the construction of a soft switch network is more systematic and advanced to better serve the development of network telecommunications and communication systems. This paper is based on the SIP protocol control technology as the core of the soft exchange. Let the network business media flow direct bear on the IP network through the soft exchange system and control and transfer in a business organization structure, which is to make the application layer control mainly in the business running on the server, the data, voice, video, news and other business processes. Through the experiment, the maximum number of registered users and the call processing ability of users in the domain of the design scheme are tested and verified, which proves that the scheme in this paper is superior to the traditional voice bearer method of the power grid to meet business needs. It can provide technical support for power grid production and lay a solid foundation for the sustainable and healthy development of the power grid in the future.
