Abstract
Due to the diversity and complexity of distribution networks, the classical modular software development method may face the difficulty in modular division, data sharing and collaboration of different specialties. Inspired by the idea of separating the control plane from the data forwarding plane in software-defined networking (SDN), a method of power data virtual plane is proposed in this paper to improve software development efficiency. Layered processing of power data virtual plane is designed to meet the diversity characteristics of intelligent distribution network and the multi-source and heterogeneous characteristics of information. This paper introduces the design idea and implementation process of virtual plane in detail. The main component of the power data virtual plane, power data warehouse and application scheduling are presented. Finally, the performance of the proposed virtual plane method is verified by practical distribution network examples with different communication networks and information.
Highlights
In recent years, due to concentrated research in academia and extensive attention to field construction of the power industry, the intelligent level of the power system has been effectively promoted
A unified format of power data for advanced applications of the intelligent distribution network can be provided by the platform which realizing the sharing of data resources in the distribution network
For the the data underlying sincewithout the virtual plane layer is introduced, theapplication device only inneeds upperto layer of distribution network. This avoids the problem of manufacturers considering how import the data into the virtual plane layer without directly contacting the advanced toapplication connect with the advanced applications of large-scale distribution network, which reduces the in upper layer of distribution network
Summary
Due to concentrated research in academia and extensive attention to field construction of the power industry, the intelligent level of the power system has been effectively promoted. In the development of advanced application software for intelligent application networks, there are some practical problems, such as the underlying communication interface and how to effectively obtain data in power application layer. With the expansion of the intelligent distribution network application software, technical problems such as data interface diversification and power data resource sharing will become more prominent during the software development process [4]. The virtual plane layer uses data warehouse to cache power data, and provides a unified data format interface to power advanced application software by the elaborate application scheduling. In this way, the proper separation of power data and communication information is realized, which is convenient for software developers of different disciplines. A unified format of power data for advanced applications of the intelligent distribution network can be provided by the platform which realizing the sharing of data resources in the distribution network
